Product details
Overview
TSB624IYPT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier designed for precision signal conditioning in automotive and industrial power supply monitoring circuits. It delivers 1.7 MHz gain bandwidth, ≤1 mV input offset voltage at 25 °C, 375 μA per channel supply current at 36 V, and operates across –40 to +125 °C. Its TSSOP14 package supports space-constrained PCB layouts in engine control units and battery management systems.
For engineers reviewing the TSB624IYPT datasheet, TSB624IYPT pinout, TSB624IYPT application, or TSB624IYPT equivalent, key selection criteria include its 36 V wide supply range, rail-to-rail output swing, 4 kV HBM ESD rating, extended temperature qualification, and verified AEC-Q100 compliance for automotive use cases.
Technical Context
The TSB624IYPT implements a bipolar-input op-amp architecture optimized for DC precision and stability under high-voltage, high-temperature conditions. It features unity-gain stable compensation, input common-mode range extending to ground, and robust phase margin (≥45°) with 100 pF capacitive load.
Its design supports single-supply operation from 2.7 V to 36 V, with supply voltage rejection ratio of 124 dB (typ.) and common-mode rejection ratio up to 135 dB (typ.), enabling accurate sensing in noisy automotive power rails and industrial analog front-ends.

|---|---|
Use Scenario: Amplifying low-level signals from knock sensors, oxygen sensors, and throttle position sensors in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Quad op-amp provides simultaneous gain, filtering, and level-shifting for four independent analog sensor channels before ADC sampling. Use Value: 1.7 MHz GBW supports anti-aliasing filter cutoffs up to 100 kHz; rail-to-rail output maximizes ADC dynamic range utilization in 3.3 V systems. |
Use Scenario: Measuring individual Li-ion cell voltages (0–4.2 V) in 12S–96S battery packs with <1 mV accuracy. IC Role / Device Role / Timing Role: Configured as unity-gain buffers to isolate high-impedance cell taps and drive multiplexed ADC inputs without loading. Use Value: ≤1 mV offset ensures ≤0.025% measurement error at 4.2 V; 125 °C rating supports operation near hot battery cells. |
| Industrial Power Supply Feedback Loop | Automotive ADAS Camera Power Sequencing |
Use Scenario: Closed-loop voltage regulation in programmable lab PSUs and telecom rectifiers requiring precise reference scaling. IC Role / Device Role / Timing Role: Implements error amplification in isolated flyback/synchronous buck feedback paths with optocoupler interface. Use Value: 36 V supply rating matches primary-side auxiliary rails; 135 dB CMRR rejects switching noise coupling into feedback traces. |

IC Role / Device Role / Timing Role: Four independent comparators (via open-loop configuration) detect undervoltage/overvoltage thresholds on each rail. Use Value: 2 µs overload recovery enables fast fault response; AEC-Q100 qualification ensures reliability in vibration-prone mounting environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB622IYDT | Dual-channel SO8 variant; identical electrical specs but half the channel count and different pinout | Used where only two precision amplifiers are needed, reducing board area vs. quad solution | Select when BOM simplification or legacy dual-channel layout reuse outweighs need for four channels on one die |
| TSB712IYST | Rail-to-rail input/output, higher precision (0.3 mV VIO), lower GBW (1.2 MHz), MiniSO8 package | Suitable for ultra-low-offset applications like strain gauge bridges where speed is secondary | Choose when sub-millivolt offset dominates design requirements and 1.2 MHz bandwidth suffices |
Compared with TSB622IYDT, the TSB624IYPT saves interconnect routing and footprint by integrating four channels; versus TSB712IYST, it trades 0.7 mV offset reduction for 0.5 MHz bandwidth headroom and automotive-grade thermal robustness.

FAQ
Is the TSB624IYPT pin-compatible with other TSB62x variants?
No. The TSB624IYPT uses a 14-pin TSSOP layout specific to the quad configuration. TSB621 (SOT23-5) and TSB622 (SO8/MiniSO8/DFN8) have distinct pin counts and assignments. Channel count, supply pin placement, and output ordering differ fundamentally across the family.
Does the TSB624IYPT support true dual-supply operation with negative voltage on VCC–?
Yes. VCC– may be driven below ground (e.g., –5 V) as long as the absolute voltage difference between VCC+ and VCC– does not exceed 40 V and the input common-mode range (VCC– –0.1 V to VCC+ –1 V) is respected. This enables bipolar signal processing in industrial instrumentation.
What is the thermal resistance (RthJA) for the TSSOP14 package?
The TSSOP14 package has a typical junction-to-ambient thermal resistance of 100 °C/W under JEDEC-standard PCB conditions (2-layer board, 1 in² copper pad). This value assumes no thermal vias or heatsinking; actual dissipation must stay below 360 mW at 125 °C ambient to avoid exceeding 150 °C junction limit.
Can the TSB624IYPT drive capacitive loads directly?
It remains stable with ≤100 pF capacitive loads at unity gain, per datasheet phase margin testing. For larger loads (e.g., >200 pF cables or ADC input capacitance), a series isolation resistor (10–100 Ω) between output and load is required to maintain ≥45° phase margin and prevent ringing.
