Product details
Overview
TSB582IYQ2T from STMicroelectronics is a dual, unity-gain stable, high-voltage (4–36 V), high-output-current (200 mA per channel) operational amplifier in automotive-qualified DFN8 3×3 mm package with exposed pad and wettable flanks. It features rail-to-rail output, low input offset (2.4 mV max at 25 °C), 3.1 MHz gain bandwidth, 2 V/µs slew rate, and integrated thermal shutdown and current limiting - designed for driving inductive loads such as angle resolvers and servo motors in harsh environments.
For engineers reviewing the TSB582IYQ2T datasheet, TSB582IYQ2T pinout, TSB582IYQ2T application, or TSB582IYQ2T equivalent, key selection criteria include its 200 mA output drive capability into low-impedance loads, extended -40 °C to +125 °C operation, enhanced RF noise immunity, 4 kV HBM ESD rating, and dual-channel bridge-tied or parallel configuration support.
Technical Context
The TSB582IYQ2T implements a BiCMOS process architecture enabling high output current while maintaining precision DC performance: input offset voltage drift ≤ ±4 µV/°C, CMRR ≥ 81 dB over full temperature range, and supply voltage rejection ratio ≥ 116 dB. Its internal protection circuitry includes thermal shutdown triggered at 168–180 °C and output current limiting active during overload conditions.
It supports rail-to-rail output swing with low saturation voltage (1.2–2.2 V drop at 150 mA), operates with common-mode input range extending to VCC− − 0.2 V, and maintains stability with capacitive loads up to 100 pF - enhanced further by optional series RISO (≤30 Ω) for >100 pF loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 36 V - enables direct use in 12 V and 24 V automotive and industrial power rails without external regulators. |
| Output Current (per channel) | 200 mA - sufficient to directly drive angle resolvers, piezo actuators, and 600 Ω line drivers without external buffers. |
| Gain Bandwidth Product | 3.1 MHz - supports closed-loop bandwidth >1 MHz at moderate gains for fast servo loop response and signal conditioning. |
| Slew Rate | 2 V/µs - ensures <1.3 µs overload recovery and preserves fidelity in pulse and transient-heavy motor control signals. |
| Input Offset Voltage | 2.4 mV max (25 °C), 3 mV max (−40 °C to +125 °C) - minimizes DC error in precision current sensing and feedback paths. |
| Input Noise Density | 45 nV/√Hz @ 1 kHz - suitable for low-noise analog front-ends in portable instrumentation and resolver excitation. |

Pinout & Package
TSB582IYQ2T is housed in a 3×3 mm DFN8 package with wettable flanks and exposed thermal pad (EP), optimized for automated optical inspection (AOI) and high thermal conductivity (RthJA = 40 °C/W). The EP may be left floating or connected to VCC− for improved heat dissipation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Out1 | Channel 1 output - capable of sourcing/sinking 200 mA; used in bridge-tied load configurations or parallel with Out2. |
| 2 | In1− | Inverting input for Channel 1 - internally protected against ±42 V differential input; requires external series resistor if Vid > ±1.3 V. |
| 3 | In1+ | Non-inverting input for Channel 1 - supports common-mode range down to VCC− − 0.2 V, enabling single-supply sensor interface. |
| 4 | VCC− | Negative supply rail - reference for both channels; EP connection point for thermal management. |
| 5 | In2+ | Non-inverting input for Channel 2 - electrically isolated from Channel 1; enables independent dual-loop control. |
| 6 | In2− | Inverting input for Channel 2 - matched bias and offset characteristics to In1− for consistent dual-channel performance. |
| 7 | Out2 | Channel 2 output - identical drive capability to Out1; supports parallel connection to double output current to 400 mA. |
| 8 | VCC+ | Positive supply rail - accepts up to 36 V; internal UVLO ensures safe startup above 4 V. |
| EP | Exposed Pad | Thermal and mechanical anchor - improves PCB heat transfer and solder joint reliability; not electrically connected by default. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output with low saturation | 1.2 V drop at 150 mA sink/source - enables full dynamic range utilization in 3.3 V–36 V systems without level-shifting. |
| Integrated thermal shutdown | Activates at 168–180 °C junction temperature - prevents permanent damage during sustained overload or poor heatsinking. |
| Dual-channel parallel operation | Enables 400 mA combined output current - eliminates need for discrete current-sharing circuits in high-power driver stages. |
| Enhanced RF noise immunity | EMIRR > 70 dB up to 1 GHz - suppresses rectified RF interference that would otherwise corrupt offset and gain in sensitive analog paths. |
| Automotive-grade qualification | AEC-Q101 qualified, -40 °C to +125 °C operation - certified for safety-critical subsystems including EPS, braking, and HVAC actuators. |
| Low input bias current | 2–5 nA over temperature - preserves accuracy in high-impedance sensor interfaces (e.g., thermistor, strain gauge bridges). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSC2017IDT | Single-channel, 150 mA output, 2.5 MHz GBW, no thermal shutdown - lower drive and protection integration. | Limited to lower-power valve drivers or single-axis feedback; unsuitable for resolver excitation or parallel operation. | Select when space constraints favor SO8 and thermal protection is managed externally. |
| LM7332MM/NOPB | Dual-channel, 60 mA output, 20 MHz GBW, rail-to-rail I/O - higher speed but insufficient current for inductive loads. | Better for high-frequency signal routing (e.g., audio, data acquisition); cannot drive resolvers or motors directly. | Choose only for bandwidth-critical, low-current applications where thermal robustness is secondary. |
Compared with TSC2017IDT and LM7332MM/NOPB, the TSB582IYQ2T uniquely combines 200 mA per channel, automotive temperature range, integrated thermal/current protection, and DFN8 space efficiency - making it the sole option for compact, ruggedized, high-current analog output stages.

FAQ
What is the maximum continuous output current per channel for TSB582IYQ2T?
The TSB582IYQ2T delivers up to 200 mA per channel continuously under specified thermal conditions (TA ≤ 85 °C, PCB copper area ≥ 200 mm², RthJA ≤ 40 °C/W). At 150 mA, output voltage drop remains ≤2.2 V from rails. Sustained 200 mA operation requires careful thermal design due to power dissipation limits.
Can TSB582IYQ2T drive capacitive loads greater than 100 pF?
Yes - with stability maintained using an output series resistor (RISO = 10–30 Ω). The datasheet confirms full stability with any capacitive load when RISO = 30 Ω is added. Without RISO, stability is guaranteed only up to 100 pF in unity-gain configuration.
Is the exposed pad of TSB582IYQ2T electrically connected?
No - the exposed pad is thermally conductive but electrically isolated. It may be left floating or soldered to VCC− for improved thermal performance. Connecting it to ground or other potentials is not recommended and voids thermal modeling assumptions in the datasheet.
Does TSB582IYQ2T support single-supply operation?
Yes - it operates with input common-mode range extending to VCC− − 0.2 V and rail-to-rail output swing, enabling true single-supply use from 4 V to 36 V. Input bias current remains low (≤5 nA), preserving accuracy in high-impedance single-ended sensor interfaces.
