Product details

Overview

TSB952IYQ2T from STMicroelectronics is a dual high-speed rail-to-rail output operational amplifier with 52 MHz gain bandwidth product, 3.3 mA max supply current per channel at 36 V, and ±3 mV input offset voltage at 25 °C. It operates from 4.5 to 36 V over −40 to +125 °C and delivers 40 mA typical output drive-designed for precision signal conditioning in automotive powertrain sensor interfaces.

For engineers reviewing the TSB952IYQ2T datasheet, TSB952IYQ2T pinout, TSB952IYQ2T application, or TSB952IYQ2T equivalent, key selection criteria include its unity-gain stability, EMI-hardened architecture, extended temperature qualification, and DFN8 3×3 mm wettable flanks package for automated optical inspection in safety-critical PCB assemblies.

Technical Context

The TSB952IYQ2T integrates two independent high-speed amplifiers sharing a common 4.5–36 V supply, each featuring rail-to-rail output swing (within 5–25 mV of rails at 36 V), input common-mode range extending to VCC−, and no phase reversal across full AMR. Its 52 MHz GBP and 30 V/µs slew rate support fast closed-loop response in active filter and current-sense amplifier topologies.

It employs EMI-hardened input stage design with 4 kV HBM ESD rating and specified EMIRR performance from 400 MHz to 2.4 GHz. The device is unity-gain stable with ≥47° phase margin into 22 pF capacitive load and supports safe operation up to 125 °C ambient when mounted in DFN8 package with exposed thermal pad.

Key Specifications

Pinout & Package

TSB952IYQ2T is supplied in DFN8 3×3 mm wettable flanks package (pitch 0.5 mm), optimized for solder joint inspection and thermal performance (R_TH-JA = 40 °C/W). The exposed thermal pad must be soldered to PCB ground plane for reliable operation at 125 °C ambient and 36 V supply.

Pin/Terminal	Circuit Role	Design Meaning
1: OUT1	Channel 1 output	Delivers rail-to-rail voltage with 40 mA sink/source capability; requires local 100 nF decoupling to VCC−
2: IN1−	Channel 1 inverting input	High-impedance node (100 pA max bias current); differential voltage limited to ±1.4 V to avoid ESD diode conduction
3: IN1+	Channel 1 non-inverting input	Common-mode range includes VCC−; internal ESD diodes clamp to rails-series resistor required if VIN exceeds supply
4: VCC−	Negative supply rail	Ground reference for dual supply or system ground in single-supply configs; connects to thermal pad
5: VCC+	Positive supply rail	4.5–36 V input; bypass with 100 nF ceramic capacitor placed <2 mm from pin
6: OUT2	Channel 2 output	Independent output with identical specs to OUT1; unused channel must be configured as unity-gain follower
7: IN2−	Channel 2 inverting input	Electrically isolated from IN1−; same ESD protection and bias current specs apply
8: IN2+	Channel 2 non-inverting input	Supports ground-referenced sensing; input offset drift ≤5 µV/°C ensures <0.5 mV error over full temp range

Key Features

Feature	Design Value
Unity-gain stable architecture	Guarantees stability with 22 pF capacitive load and no external compensation-reduces BOM count in motor control feedback loops
Wettable flanks DFN8 package	Enables automated optical inspection (AOI) of solder joints on bottom-side terminations-critical for zero-defect automotive manufacturing
EMI-hardened input stage	Meets ISO 11452-2 radiated immunity requirements without added ferrites or shielding in 12 V battery monitoring circuits
Rail-to-rail output with 40 mA drive	Eliminates need for external push-pull buffer when driving analog inputs of microcontrollers with 3.3 V I/O domains
AEC-Q100 Grade 0 qualification	Validated for operation at 125 °C junction temperature-supports placement near power MOSFETs in DC-DC converter controllers

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual high-speed rail-to-rail output op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSB952IDT	Same silicon die, SO8 package (R_TH-JA = 125 °C/W) - lower thermal performance than DFN8	Suitable for lower-power 5 V/12 V designs where board space permits larger footprint and AOI is not required	Select when legacy SO8 layout reuse is prioritized over thermal density and automated inspection capability
TSB612IYQ2T	Lower quiescent current (1.2 mA/ch), reduced GBP (12 MHz), same DFN8 package and AEC-Q100 Grade 0 rating	Better suited for always-on battery monitoring where 52 MHz bandwidth is unnecessary and power budget is constrained	Choose when system-level power consumption dominates over signal fidelity and transient response requirements

Compared with TSB952IDT, the TSB952IYQ2T offers 3.1× lower thermal resistance enabling full 36 V/125 °C operation, while TSB612IYQ2T trades 4.3× lower bandwidth for 2.8× reduced supply current-making each optimal for distinct thermal, speed, and power trade-offs in automotive subsystems.

FAQ

What is the maximum safe supply voltage for continuous operation at 125 °C ambient?

The TSB952IYQ2T in DFN8 package supports continuous operation at 36 V supply and 125 °C ambient temperature, provided the thermal pad is fully soldered to a minimum 200 mm² copper pour on inner layer 2. Junction temperature remains below 150 °C due to R_TH-JA = 40 °C/W. Operation above 36 V violates absolute maximum rating and risks permanent damage.

How should the unused channel be configured to prevent oscillation and excess current draw?

The unused channel must be configured as a unity-gain voltage follower with IN+ tied to a stable DC bias within the common-mode range (e.g., VCC/2 via resistor divider). Direct shorting of IN+ to IN− or leaving inputs floating causes internal instability, increasing supply current by up to 2.5× and degrading noise performance of the active channel.

Does the device require external compensation for driving 100 pF capacitive loads?

Yes-capacitive loads >22 pF require series output isolation resistor R_ISO. For 100 pF, a 47 Ω resistor between OUT and load restores ≥47° phase margin and eliminates ringing. Without R_ISO, gain peaking occurs at ~2.5 MHz causing overshoot >20% in step response and potential instability in closed-loop configurations.

Can the TSB952IYQ2T be used as a comparator?

No-it is not designed or characterized for open-loop comparator operation. Input differential voltage must be limited to ±1.4 V to prevent ESD diode conduction and excessive current. When used in saturation (e.g., as comparator), recovery time exceeds 80 ns and input stage may experience phase reversal outside guaranteed common-mode range, risking latch-up.
