Product details
Overview
TS982IYDWT from STMicroelectronics is a dual bipolar operational amplifier in SO-8 exposed-pad package, delivering 200 mA output current per channel at supply voltages from 2.5 V to 5.5 V, with rail-to-rail input/output and unity-gain stability-designed for high-current analog signal conditioning in automotive motor drivers and industrial servo amplifiers.
For engineers reviewing the TS982IYDWT datasheet, TS982IYDWT pinout, TS982IYDWT application, or TS982IYDWT equivalent, this page provides verified electrical parameters, thermal management guidance for the exposed-pad package, real-world use cases in Hall sensor compensation and motor drive stages, and validated alternative op-amps with documented output current and voltage range differences.
Technical Context
The TS982IYDWT integrates two independent high-output-current bipolar op-amps on a single die, each capable of sourcing/sinking 200 mA into low-impedance loads (e.g., 16 Ω) while maintaining rail-to-rail swing and stable operation at unity gain. Its SO-8 exposed-pad package enables direct thermal coupling to PCB copper, achieving Rthjc = 10 °C/W and Rthja = 45 °C/W under JEDEC JESD51-7 conditions.
It operates across -40 °C to +125 °C with input offset voltage ≤7 mV, input bias current ≤500 nA, and phase margin ≥56° at 16 Ω load with 400 pF capacitance-enabling robust performance in closed-loop current-sensing and precision actuator control without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct interface with 3.3 V and 5 V microcontrollers and logic systems. |
| Output Current per Channel | 200 mA - drives low-impedance loads such as motor windings, solenoids, or Hall sensor compensation coils without external buffers. |
| Input Offset Voltage | ≤7 mV - ensures <±0.3% error in 2.5 V–5.5 V full-scale sensing applications like current feedback loops. |
| Gain Bandwidth Product | 1.2–2.2 MHz - enables stable closed-loop bandwidth up to ~100 kHz for servo position control with 16 Ω load. |
| Phase Margin | ≥56° at unity gain - guarantees unconditional stability with capacitive loads up to 400 pF, critical for motor driver feedback paths. |
| Thermal Resistance (Junction-to-Case) | 10 °C/W - allows >2 W continuous dissipation when mounted on ≥6 cm² top-side copper, essential for automotive under-hood environments. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1, suitable for engine bay and industrial control cabinet deployment. |
Pinout & Package
The TS982IYDWT is housed in an SO-8 exposed-pad plastic micropackage (DW variant), where the underside thermal pad must be soldered to a PCB copper area connected to VCC− (pin 4) for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Non-inverting input (amp 1) | High-impedance differential input node for positive feedback or reference biasing. |
| 2 | Inverting input (amp 1) | Differential input node accepting feedback signals or sensor inputs with common-mode range GND to VCC. |
| 3 | Output (amp 1) | High-current output stage capable of sourcing/sinking 200 mA into 16 Ω loads with <1 V saturation voltage. |
| 4 | VCC− (ground) | Power return and substrate reference; exposed thermal pad must be electrically tied to this pin. |
| 5 | Output (amp 2) | Independent high-current output identical in capability to pin 3, enabling dual-channel drive or parallel configuration. |
| 6 | Inverting input (amp 2) | Second differential input with same CMR (75–80 dB) and bias current (≤500 nA) as channel 1. |
| 7 | Non-inverting input (amp 2) | Second high-impedance input for independent signal conditioning path. |
| 8 | VCC+ | Positive supply rail; accepts 2.5–5.5 V with 6 V absolute maximum rating. |
Key Features
| Feature | Design Value |

| Unity-gain stable | Eliminates need for external compensation components in voltage-follower or gain-of-1 current-sense amplifier configurations. |
| Exposed thermal pad | Reduces junction-to-ambient thermal resistance by >50% vs. standard SO-8, sustaining 200 mA output at +125 °C ambient. |
| AEC-Q100 qualified | Validated for automotive applications including engine control modules and EPS motor drivers requiring Grade 1 reliability. |

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 |
|---|---|---|---|
| TSC1021IYPT | Single-channel current sense amplifier with 2.7–5.5 V supply, 100 µV max offset, but only 20 mA output current. | Limited to low-power current monitoring; cannot drive coils or motors directly. | Select when precision <100 µV offset is required and load current <20 mA. |
| LM7332MME/NOPB | Dual rail-to-rail op-amp with 60 mA output current, 24 V max supply, but no AEC-Q100 qualification or exposed-pad thermal design. | Suitable for lab-grade instrumentation but not automotive under-hood or industrial high-temp deployments. | Select for wide-supply (±12 V) analog front-ends where thermal dissipation <1 W is sufficient. |
Compared with TS982IYDWT, TSC1021IYPT trades output current for ultra-low offset in sensing-only roles, while LM7332MME/NOPB offers wider supply range but lacks the thermal robustness and automotive qualification needed for sustained 200 mA operation at +125 °C.

FAQ
What is the maximum continuous output current per channel for TS982IYDWT?
The TS982IYDWT delivers 200 mA per channel continuously into 16 Ω loads at VCC = 5 V and Tamb = 25 °C, with derating to 100 mA at Tamb = 125 °C when mounted on a 2-layer PCB with 6 cm² top-side copper. This is confirmed in Table 3 of the datasheet under VOH/VOL test conditions with Iout = 200 mA.
How must the exposed thermal pad be connected on the PCB?
The exposed pad on the underside of the TS982IYDWT SO-8 package must be soldered to a PCB copper area electrically connected to pin 4 (VCC−). Per Section 3.2 of the datasheet, this connection provides both thermal conduction and substrate voltage reference, and floating or grounding the pad to a different potential risks instability or latch-up.
Is TS982IYDWT qualified for automotive applications?
Yes-TS982IYDWT is explicitly qualified per AEC-Q100 Grade 1 (-40 °C to +125 °C) and subjected to advanced screening per AEC-Q001/Q002, as stated in Table 7 of the datasheet. It is designated for automotive use in motor drivers, HVAC actuators, and electronic power steering subsystems.
Can both amplifiers be operated in parallel to increase output current?
Yes-the datasheet confirms parallel operation in Section 3.5, enabling 400 mA total output current when both channels are connected in-phase with matched feedback networks. Figure 43 shows the recommended layout, and thermal design must account for doubled power dissipation using ≥12 cm² of top-side copper.
