Product details
Overview
TSB952IYDT from STMicroelectronics is a dual high-speed rail-to-rail output operational amplifier with 52 MHz gain bandwidth product, ±3 mV max input offset voltage at 25 °C, and 4.5–36 V wide supply range-designed for precision signal conditioning in automotive powertrain control units and industrial motor drive current sensing circuits.
For engineers reviewing the TSB952IYDT datasheet, TSB952IYDT pinout, TSB952IYDT application, or TSB952IYDT equivalent, key selection criteria include its unity-gain stability, 40 mA output drive capability at 36 V, -40 to +125 °C extended temperature qualification, EMI-hardened architecture, and DFN8 3×3 mm wettable flanks package for automated optical inspection (AOI) compatibility.
Technical Context
The TSB952 operates as a dual-channel voltage-feedback op amp with fully differential input stage and Class-AB rail-to-rail output stage. Its 52 MHz GBP at 36 V enables fast settling (345 ns to 0.01%) and 30 V/µs slew rate, while maintaining low quiescent current (3.3 mA per channel).
It features input common-mode range extending to VCC− (ground-referenced inputs), no phase reversal across full AMR, and internal ESD diodes rated to 4 kV HBM. The device is unity-gain stable with ≥47° phase margin into 22 pF capacitive load without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 52 MHz typ. @ 36 V - supports closed-loop bandwidth up to ~45 MHz in unity-gain configuration for high-fidelity signal amplification. |
| Input Offset Voltage | ±3 mV max @ 25 °C - enables accurate DC-coupled measurement in current-sense and sensor interface applications without trimming. |
| Supply Voltage Range | 4.5 to 36 V - compatible with 12 V and 24 V automotive battery rails and industrial 24/36 V power systems. |
| Output Drive Current | 40 mA typ. @ 36 V - drives low-impedance loads (e.g., 600 Ω cables or ADC input networks) without external buffers. |
| Common-Mode Input Range | VCC− to VCC+ − 1.5 V - accepts ground-referenced inputs while rejecting supply noise via 105 dB CMRR @ 12 V. |
| EMI Hardening | EMIRR > 70 dB @ 900 MHz - suppresses RF rectification-induced offset shifts in noisy engine bay or factory floor environments. |
| Temperature Range | −40 to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use and harsh industrial settings. |
Pinout & Package
TSB952IYDT is supplied in a DFN8 3×3 mm package with wettable flanks for reliable solder-joint inspection. Thermal resistance RTH-JA = 40 °C/W enables operation at full 36 V supply and 125 °C ambient when properly mounted on 2s2p PCB.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 rail-to-rail output capable of sourcing/sinking 40 mA; connects directly to ADC input or transimpedance node. |
| 2 | IN1− | Inverting input of Channel 1; internal ESD diodes clamp to VCC+/VCC−; requires series resistor if VICM exceeds rails. |
| 3 | IN1+ | Non-inverting input of Channel 1; supports ground-referenced signals; input bias current ≤100 pA @ 125 °C. |
| 4 | VCC− | Negative supply rail (GND for single-supply operation); shared return path for both channels and thermal pad. |
| 5 | VCC+ | Positive supply rail (up to 36 V); decoupling capacitor required within 2 mm for high-frequency stability. |
| 6 | OUT2 | Channel 2 rail-to-rail output; electrically isolated from OUT1 but shares thermal and supply paths. |
| 7 | IN2− | Inverting input of Channel 2; identical electrical behavior to IN1−; unused channel must be configured as unity-gain follower. |
| 8 | IN2+ | Non-inverting input of Channel 2; independent bias network; supports separate sensor or reference inputs per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Within 10 mV of rails @ no load and 50 mV @ 2 mA sink/source - preserves dynamic range in low-voltage ADC interfaces. |
| Unity-gain stability | Guaranteed ≥47° phase margin into 22 pF load - eliminates need for external compensation in most buffer/follower designs. |
| Low input offset drift | 0.8–1.0 µV/°C max - limits total error to <12 µV over −40 to +125 °C, critical for uncalibrated industrial sensors. |
| High ESD tolerance | 4 kV HBM - withstands handling and board-level ESD events without latch-up or parameter shift. |
| Wettable flank leads | DFN8 3×3 mm package geometry - enables automated X-ray and AOI verification of solder fillet integrity for automotive PPAP compliance. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB612IDT | Lower supply current (1.2 mA/ch @ 36 V), reduced GBP (12 MHz), same package and temp range. | Better suited for always-on battery-powered nodes where speed is secondary to power savings. | Select when 12 MHz bandwidth suffices and quiescent current reduction outweighs settling time penalty. |
| TSB712IYDT | Rail-to-rail inputs + outputs, higher precision (±150 µV VIO), lower GBP (22 MHz), same DFN8 package. | Preferred for DC-critical applications like precision thermocouple amplification requiring input common-mode to both rails. | Choose when input rail-to-rail operation and sub-mV offset dominate over bandwidth and slew rate. |
Compared with TSB612IDT and TSB712IYDT, the TSB952IYDT uniquely balances 52 MHz bandwidth, 40 mA drive, and automotive temperature range in a wettable-flank DFN8-making it optimal for high-dynamic-range signal chains where speed, robustness, and manufacturability are jointly prioritized.

FAQ
What is the maximum safe supply voltage for TSB952IYDT in continuous operation?
The absolute maximum supply voltage is 40 V, but continuous operation is limited to 36 V per datasheet specifications. Exceeding 36 V risks parametric degradation and violates AEC-Q100 stress conditions. At 36 V and 125 °C ambient, the DFN8 package remains within 150 °C junction limit only with proper PCB copper area and thermal vias-SO8 is not recommended at these extremes.
Can TSB952IYDT drive a 1000 pF capacitive load in unity-gain configuration?
Yes, but only with a 47 Ω series isolation resistor (RISO) placed between the output pin and the capacitive load. Without RISO, instability occurs beyond 22 pF due to phase margin erosion. The 47 Ω value maintains DC accuracy while ensuring ≥47° phase margin and eliminating ringing, as verified in Figure 52 of DS14576.
How should the unused channel be terminated to prevent oscillation?
The unused channel must be configured as a unity-gain voltage follower: connect IN+ to a stable DC bias within the common-mode range (e.g., VCC/2 via resistive divider), tie IN− to OUT, and leave OUT unconnected except for optional 100 pF bypass to GND. Floating inputs or open-loop configurations cause supply current increase and crosstalk into the active channel.
Is TSB952IYDT pin-compatible with other ST dual op amps in DFN8?
No-TSB952IYDT has a unique 8-pin DFN layout (OUT1, IN1−, IN1+, VCC−, VCC+, OUT2, IN2−, IN2+) optimized for dual-channel symmetry. TSB612IDT and TSB712IYDT use different pinouts; direct replacement requires PCB redesign. Always verify pin mapping against DS14576 Figure 2 before layout reuse.
