Product details
Overview
TSB582IDT from STMicroelectronics is a dual, unity-gain-stable, high-voltage (4–36 V), high-output-current (200 mA per channel) operational amplifier with rail-to-rail output and low-rail input capability. It integrates thermal shutdown, output current limiting, 4 kV HBM ESD tolerance, and enhanced RF noise immunity. Designed for driving inductive loads such as angle resolvers and piezo actuators in automotive-grade industrial systems.
For engineers reviewing the TSB582IDT datasheet, TSB582IDT pinout, TSB582IDT application, or TSB582IDT equivalent, key selection criteria include its 3.1 MHz gain bandwidth, 2 V/µs slew rate, ±42 V absolute maximum supply, -40 °C to +125 °C operating range, and dual-channel high-current drive capability in SO8 and DFN8 exposed-pad packages.
Technical Context
The TSB582IDT employs a BiCMOS process enabling simultaneous high voltage operation (up to 36 V), high output current (200 mA/channel), and precision DC performance (2.4 mV max offset at 25 °C). Its internal protection architecture includes thermal shutdown triggered at 168–180 °C and current limiting that sustains safe operation under overload or short-circuit conditions.
It supports bridge-tied load (BTL) configurations and parallel channel operation to double sink/source current. Input common-mode range extends from VCC− to VCC+ − 1.5 V, and it maintains stability with capacitive loads up to 100 pF - improved further with optional 10–30 Ω series output isolation resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4 V to 36 V - enables direct integration into 12 V/24 V automotive and industrial power rails without external regulators. |

| Gain Bandwidth Product | 3.1 MHz @ 36 V - supports closed-loop bandwidth >1 MHz in unity-gain configuration for fast servo control loops. |
| Slew Rate | 2 V/µs - ensures <1.3 µs overload recovery and accurate reproduction of fast transient signals in motor control feedback paths. |
| Input Offset Voltage | 2.4 mV max @ 25 °C - enables sub-0.1% accuracy in precision current sensing and analog signal conditioning over temperature. |
| ESD Rating | 4 kV HBM - meets AEC-Q101-001 requirements for robustness in harsh automotive environments. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and industrial control applications with full parameter guarantee across range. |

Pinout & Package
TSB582IDT is available in two automotive-qualified packages: SO8 with exposed pad (EP) and DFN8 (3 × 3 mm) with wettable flanks and exposed pad. Both support thermal enhancement via soldered EP connection to PCB ground or VCC−.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Out1) | Channel 1 output | High-current source/sink node capable of 200 mA; connects directly to inductive load or BTL stage. |
| 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 | High-impedance input (2 nA bias current) supporting wide common-mode range (VCC− to VCC+ − 1.5 V). |
| 4 (VCC−) | Negative supply rail | Reference for both channels; exposed pad may be connected here to improve thermal conduction and reduce junction temperature. |
| 5 (In2+) | Channel 2 non-inverting input | Independent high-Z input identical to In1+, enabling dual-sensor conditioning or differential drive configurations. |
| 6 (In2−) | Channel 2 inverting input | Matches In1− specs; supports independent feedback networks for each amplifier channel. |
| 7 (Out2) | Channel 2 output | Second 200 mA output; used in parallel mode (doubling current) or BTL with Out1 for higher-voltage swing. |
| 8 (VCC+) | Positive supply rail | Accepts up to 42 V absolute max; powers both amplifiers and internal protection circuitry. |
| ep (Exposed Pad) | Thermal & electrical ground | Not electrically required but thermally critical - must be soldered to PCB copper for specified RthJA (40/45 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output + low-rail input | Enables full dynamic range utilization in single-supply 12 V/24 V systems, e.g., valve driver feedback loops with 0–10 V output compliance. |
| Internal thermal shutdown | Auto-recovery at 130–146 °C reset threshold prevents latch-up during sustained overload - eliminates need for external thermal fuses in servo drivers. |
| 200 mA per channel with current limiting | Supports direct drive of 60 Ω loads at 12 V (200 mA × 60 Ω = 12 V drop), eliminating discrete output transistors in resolver excitation circuits. |
| Enhanced RF noise immunity | EMIRR >60 dB up to 1 GHz minimizes offset shift from GSM/ISM-band interference - critical for automotive body control modules near wireless transceivers. |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation in line driver and motor phase current sensing applications where capacitive cable loads exceed 50 pF. |
| Low 45 nV/√Hz input noise | Preserves SNR in precision analog front-ends for portable instrumentation and industrial process controllers measuring µV-level sensor outputs. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSC2010IDT | Single-channel, 150 mA output, 2.5 MHz GBW, no thermal shutdown | Lacks dual-channel capability and internal protection - requires external current limiting and thermal monitoring circuitry | Select only when single-channel operation suffices and board space allows added protection components. |
| LM7332MME/NOPB | Dual-channel, 60 mA output, 20 MHz GBW, rail-to-rail I/O, no current limiting | Higher speed but insufficient output current for resolver/valve loads; not AEC-Q101 qualified | Prefer for high-bandwidth signal conditioning only; unsuitable for direct inductive load driving. |
Compared with TSC2010IDT and LM7332MME/NOPB, the TSB582IDT uniquely combines dual 200 mA outputs, automotive qualification, integrated thermal/current protection, and 36 V operation - making it the only drop-in solution for safety-critical, high-power analog output stages in automotive and industrial motion control.

FAQ
What is the maximum continuous output current per channel for TSB582IDT?
The TSB582IDT delivers up to 200 mA per channel continuously under thermal limits. At 36 V supply and 25 °C ambient, this corresponds to ~1.5 W dissipation in SO8 (RthJA = 45 °C/W), requiring ≥4 cm² of 2-oz copper on the PCB. Derating applies above 85 °C ambient per Figure 29/30 SOA curves.
Can TSB582IDT drive capacitive loads greater than 100 pF?
Yes - with stability maintained up to 100 pF in unity-gain configuration. For larger loads, insert a 10–30 Ω series resistor (RISO) between output and load. At RISO = 30 Ω, stability is guaranteed regardless of capacitance, though output voltage drop must be accounted for in precision applications.
Is the exposed pad electrically connected internally?
No - the exposed pad is thermally conductive but electrically isolated. It may be left floating or connected to VCC− for optimal thermal performance. ST recommends soldering it to a large copper pour tied to VCC− to achieve the rated RthJA of 40 °C/W (DFN8) or 45 °C/W (SO8).
How does the internal thermal shutdown behave during overload?
When junction temperature exceeds 168–180 °C, the output stage disables automatically. Output resumes when die cools to 130–146 °C. This cycle prevents permanent damage but is not intended for continuous operation - system design must ensure average power stays within SOA limits using PCB copper area or heatsinking.
