Product details
Overview
TSB582IYDT from STMicroelectronics is a dual, unity-gain-stable, high-voltage (4–36 V), high-output-current (200 mA per channel) operational amplifier in SO8 exposed-pad package, featuring rail-to-rail output, 3.1 MHz gain bandwidth, 2 V/µs slew rate, and integrated thermal shutdown and current limiting - designed for driving low-impedance inductive loads such as angle resolvers and servo motors in automotive power stages.
For engineers reviewing the TSB582IYDT datasheet, TSB582IYDT pinout, TSB582IYDT application, or TSB582IYDT equivalent, this part supports bridge-tied load configurations, parallel-channel current doubling, and operates across -40 °C to +125 °C with AEC-Q101 qualification - critical for industrial motor control, valve driver, and DC power supply designs requiring robust ESD (4 kV HBM) and RF noise immunity.
Technical Context
The TSB582IYDT implements a BiCMOS input stage with enhanced ESD protection circuitry and internal thermal sensing that triggers output disable above ~175 °C junction temperature, with automatic recovery below ~140 °C. Its differential input stage tolerates ±42 V differential voltage and accepts common-mode inputs down to VCC−, enabling direct interfacing with ground-referenced sensors in high-side sensing topologies.
Each amplifier channel delivers up to 200 mA sink/source into resistive or inductive loads while maintaining stability with capacitive loads up to 100 pF (or higher with 10–30 Ω series isolation resistor). The device achieves 45 nV/√Hz input noise at 1 kHz and <0.007% THD+N at 1 kHz, supporting precision analog signal conditioning in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4 V to 36 V - enables single-supply operation in 12 V/24 V automotive and industrial systems without level-shifting. |
| Output Current | 200 mA per channel - sufficient to directly drive 10 Ω inductive loads (e.g., solenoid valves, resolver primaries) without external buffers. |
| Gain Bandwidth | 3.1 MHz @ 36 V - supports closed-loop bandwidth >100 kHz in unity-gain configurations for fast transient response in servo loops. |
| Slew Rate | 2 V/µs - ensures <5 µs settling time for 10 V step outputs, critical for line drivers and motor phase control signals. |
| Input Offset Voltage | ±2.4 mV max @ 25 °C - enables accurate DC-coupled amplification of low-level sensor signals (e.g., current shunt, position feedback). |
| ESD Rating | 4 kV HBM - meets AEC-Q101-001, reducing need for external TVS diodes in harsh automotive ECU environments. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood and industrial control applications where ambient thermal stress exceeds commercial-grade limits. |
| Thermal Shutdown | Activates at ~175 °C junction - protects against sustained overload or poor PCB heatsinking without latch-up or permanent damage. |
Pinout & Package
TSB582IYDT is housed in an SO8 package with exposed pad (EP), optimized for thermal dissipation in high-power analog stages. The exposed pad must be soldered to a large copper pour for effective heat transfer (RthJA = 45 °C/W typical).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Out1) | Channel 1 output | Delivers up to 200 mA sink/source; supports bridge-tied or parallel configuration with Out2. |
| 2 (In1−) | Channel 1 inverting input | Differential input node with ±42 V absolute max rating; requires external current limiting if Vid > 1.3 V. |
| 3 (In1+) | Channel 1 non-inverting input | Accepts common-mode voltage from VCC− to VCC+ − 1.5 V; enables ground-referenced sensor interface. |
| 4 (VCC−) | Negative supply rail | Reference for both channels; exposed pad may be connected to this pin for lowest thermal resistance. |
| 5 (In2+) | Channel 2 non-inverting input | Independent input for second channel; allows dual-sensor conditioning or complementary drive signals. |
| 6 (In2−) | Channel 2 inverting input | Matches In1− specs; supports differential feedback networks for precision gain control. |
| 7 (Out2) | Channel 2 output | Electrically identical to Out1; enables current doubling when paralleled with Out1 (requires matched layout). |
| 8 (VCC+) | Positive supply rail | Supports up to 42 V absolute max; decoupling capacitor (≥22 nF) required between VCC+ and VCC− near the package. |
| EP | Exposed thermal pad | Not electrically active; must be soldered to PCB ground or VCC− plane to achieve rated RthJA and prevent thermal derating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full dynamic range utilization with 36 V supply - e.g., ±17.5 V swing into 100 Ω load without clipping. |
| Internal current limiting | Self-protecting 200 mA limit prevents destructive latch-up during short-circuit or inductive kickback events. |
| Enhanced RF noise immunity | EMIRR >60 dB from 10 MHz–1 GHz reduces offset drift induced by GSM/Bluetooth interference in vehicle ECUs. |
| Low input bias current | 2 nA typ. - minimizes voltage error across high-impedance sensor bridges (e.g., strain gauges, RTDs) without compensation. |
| Unity-gain stable | No external compensation required - simplifies design of transimpedance amps, active filters, and voltage followers. |
| Wettable flank compatibility | SO8 EP variant supports automated optical inspection (AOI) of solder joints - improves manufacturing yield in automotive production. |
Applications
| Servo Driver | Valve Driver |
|---|---|
Use Scenario: Closed-loop position control of brushed DC or stepper motor using encoder feedback and PWM-driven H-bridge. IC Role / Device Role / Timing Role: Dual op-amp configures as error amplifier and current sense amplifier - one channel conditions encoder signal, the other monitors motor phase current. Use Value: 200 mA output drives gate resistors of MOSFET half-bridges directly; rail-to-rail swing maximizes PWM duty cycle resolution at low supply voltages. |
Use Scenario: Proportional control of hydraulic/pneumatic solenoid valves in industrial automation or off-road vehicle hydraulics. IC Role / Device Role / Timing Role: High-current buffer between microcontroller DAC and inductive valve coil - provides fast turn-on/turn-off with controlled dI/dt. Use Value: 2 V/µs slew rate limits inductive voltage spikes (<100 V); thermal shutdown prevents coil burnout during stuck-valve fault conditions. |
| Angle Resolver Interface | Industrial DC Power Supply |
Use Scenario: Excitation and demodulation of resolver sine/cosine windings in electric power steering (EPS) or traction motor control. IC Role / Device Role / Timing Role: One channel generates 10 kHz excitation signal; second channel amplifies low-amplitude resolver feedback for ADC sampling. Use Value: 3.1 MHz GBP supports clean 10 kHz sine generation with <0.007% THD+N; low 45 nV/√Hz noise preserves SNR in 12-bit resolver-to-digital conversion. |
Use Scenario: Programmable bench power supply with remote sense, current limiting, and thermal foldback protection. IC Role / Device Role / Timing Role: Dual op-amp implements voltage and current error amplifiers in feedback loop - regulates output via pass transistor base/gate drive. Use Value: Internal current limiter and thermal shutdown replace discrete protection circuits; 4–36 V supply range supports 3.3 V logic interface and 30 V output capability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSC2010IDT | Single-channel, 150 mA output, 2.5 MHz GBP, no thermal shutdown | Lacks dual-channel integration and overtemperature protection - requires external thermal monitoring | Preferred only when board space is constrained and thermal management is handled externally |
| LM7332MME/NOPB | Dual-channel, 60 mA output, 20 MHz GBP, rail-to-rail I/O, no current limiting | Higher speed but insufficient output current for inductive loads - unsuitable for resolver/servo drive | Applicable only in low-power signal conditioning where 200 mA drive is not required |
Compared with TSC2010IDT and LM7332MME/NOPB, the TSB582IYDT uniquely combines dual-channel 200 mA drive, integrated thermal/current protection, and AEC-Q101 qualification - making it the only drop-in solution for automotive-grade servo, valve, and resolver interfaces requiring functional safety margins.

FAQ
What is the maximum continuous output current per channel for TSB582IYDT?
The TSB582IYDT delivers up to 200 mA per channel continuously under thermal-limited conditions (Ta ≤ 85 °C, RthJA = 45 °C/W, VCC = 36 V). At higher ambient temperatures or with inadequate PCB copper, output current must be derated per the SOA curves in DS13378 Rev 3, page 19. Peak currents exceeding 200 mA are permitted briefly but trigger internal current limiting.
Can TSB582IYDT drive capacitive loads without oscillation?
Yes - the TSB582IYDT is unity-gain stable and supports up to 100 pF capacitive load without external compensation. For loads >100 pF, adding a 10–30 Ω series resistor (RISO) at the output eliminates ringing while preserving DC accuracy. Figure 31 in DS13378 Rev 3 confirms stability with RISO = 30 Ω across all capacitive values.
Is the exposed pad of TSB582IYDT electrically connected?
No - the exposed pad is thermally conductive but electrically isolated. It must be soldered to a PCB copper area tied to VCC− (pin 4) or system ground to achieve the specified 45 °C/W thermal resistance. Leaving it floating increases junction temperature by >20 °C under full load and risks thermal shutdown.
Does TSB582IYDT support single-supply operation with input referenced to ground?
Yes - its input common-mode range extends to VCC− (ground in single-supply mode), allowing direct connection of ground-referenced sensors (e.g., shunt resistors, potentiometers). However, the minimum common-mode voltage is VCC−, not below it, so negative input signals require dual-supply configuration.
