Product details
Overview
TSV855AIPT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier with integrated shutdown functionality, designed for automotive signal conditioning and battery-powered instrumentation. It delivers 1.3 MHz gain bandwidth, 0.8 mV max input offset voltage at 25 °C, 180 µA per channel supply current at 5 V, and operates across -40 °C to +125 °C in TSSOP16 package.
For engineers reviewing the TSV855AIPT datasheet, TSV855AIPT pinout, TSV855AIPT application, or TSV855AIPT equivalent, this page provides verified electrical specifications, validated shutdown timing (300 ns turn-on), rail-to-rail output behavior under 2 kΩ load, and automotive-grade thermal and ESD performance (4 kV HBM, 125 °C operation).
Technical Context
The TSV855AIPT integrates four independent op-amps with individual shutdown control pins (SHDN1/SHDN2/SHDN3/SHDN4), enabling selective channel power gating. Its input stage supports common-mode voltage down to VCC− − 0.2 V and up to VCC+ − 1 V, with no phase reversal - critical for single-supply sensor front-ends.
It features rail-to-rail output swing (≤100 mV from rails at 10 kΩ), 60° phase margin with 200 pF capacitive load, and 0.7 V/µs slew rate at 5 V. Shutdown mode reduces supply current to 50 nA per channel, with output placed in high-impedance state and leakage ≤1 nA over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.3 MHz - enables stable unity-gain buffer or 10× gain amplification up to 130 kHz without peaking. |
| Input Offset Voltage (max) | 0.8 mV at 25 °C - ensures ≤0.8 mV DC error in precision sensor signal chains without trimming. |
| Supply Current (per channel) | 180 µA at 5 V - supports >1-year battery life in 10 µA-systems with duty-cycled operation. |
| Shutdown Current (per channel) | 50 nA at 25 °C - reduces quiescent draw by 3600× versus active mode, critical for always-on monitoring nodes. |
| Rail-to-Rail Output Swing | ≤100 mV from VCC+/VCC− at 10 kΩ - preserves dynamic range in 3.3 V or 5 V single-supply data acquisition systems. |
| Operating Temperature Range | −40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor control feedback paths. |
| ESD Robustness (HBM) | 4 kV on all pins except SHDN; 3.5 kV on SHDN - withstands handling and board-level transients without protection diodes. |
Pinout & Package
TSSOP16 package: 4.4 mm × 5.0 mm × 1.2 mm body, 0.65 mm pitch, exposed pad optional (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | In+ (non-inverting input) | Accepts signals from 0.2 V below VCC− to 1 V below VCC+; no phase reversal across full range. |
| 2, 6, 10, 14 | In− (inverting input) | Differential pair input node; bias current ≤60 nA at 25 °C enables high-Z sensor interfacing. |
| 3, 7, 11, 15 | Out (output) | Rail-to-rail capable; sinks 43 mA / sources 70 mA at 5 V; high-Z in shutdown mode. |
| 4, 12 | VCC− (negative supply) | Ground reference for single-supply operation; supports 2.3 V to 5.5 V total supply range. |
| 8, 16 | VCC+ (positive supply) | Primary power rail; decoupling capacitor required within 2 mm for stability with 200 pF load. |
| 17, 18, 19, 20 | SHDN1/2/3/4 | Active-high logic control; <0.5 V disables channel, >VCC− + 0.5 V enables; 10 pA leakage at logic levels. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel with per-channel shutdown | Independent enable/disable of each op-amp reduces system-level power by >99% during idle phases. |
| Automotive qualification (AEC-Q100 Grade 1) | Validated for 125 °C ambient operation and 1000-cycle temperature cycling - suitable for engine control modules. |
| Low input offset drift | 1 µV/°C max over −40 °C to +125 °C - maintains <1.2 mV total offset shift across full automotive temperature range. |
| High ESD tolerance on SHDN pin | 3.5 kV HBM - allows direct connection to microcontroller GPIO without series resistance or clamping. |
| Stable with 200 pF capacitive load | 60° phase margin at 5 V - eliminates need for isolation resistors in driving ADC input filters or long PCB traces. |
Applications
| Automotive Cabin Pressure Sensing | Portable ECG Front-End |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp with shutdown applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV855IPT | No shutdown function; identical offset, GBW, and supply current; same TSSOP16 pinout except SHDN pins repurposed as NC. | Lacks per-channel power gating - unsuitable for ultra-low-power duty-cycled systems. | Select when shutdown is unnecessary and cost reduction is prioritized; pin-compatible drop-in replacement for non-shutdown designs. |
| LMV854MT/NOPB | Higher 5.5 MHz GBW but 2.5 mV offset; 250 µA/channel supply current; no automotive qualification; SO14 package only. | Supports higher-frequency active filters but requires calibration for DC accuracy; not rated for 125 °C operation. | Choose for bandwidth-critical audio or ultrasonic sensing where temperature range is limited to −40 °C to +85 °C. |
Compared with TSV855IPT, the TSV855AIPT adds essential shutdown control at minimal cost premium while retaining identical precision and thermal robustness; versus LMV854MT/NOPB, it trades bandwidth for guaranteed automotive reliability and lower quiescent power.

FAQ
What is the maximum capacitive load the TSV855AIPT can drive while maintaining stability?
The TSV855AIPT maintains ≥60° phase margin with up to 200 pF capacitive load at 5 V supply, as confirmed in Figure 11 of the datasheet. Driving >200 pF requires an external isolation resistor (≥100 Ω) between output and load to prevent peaking or oscillation, especially in unity-gain configurations.
Can the SHDN pins be tied together and controlled by a single microcontroller GPIO?
Yes - all four SHDN pins are electrically isolated and accept standard CMOS logic levels. They may be paralleled and driven by one GPIO, reducing MCU pin count. Each SHDN draws only 10 pA at logic high, so fan-out is not limiting even with multiple devices on the same line.
Does the TSV855AIPT support true single-supply operation with input voltages at ground?
Yes - its input common-mode range extends to VCC− − 0.2 V, allowing direct connection of sensors referenced to ground in 2.3–5.5 V single-supply systems. No level-shifting circuitry is needed for 0 V input signals, simplifying front-end design for bridge or thermistor interfaces.
How does the output behave during shutdown?
When any SHDN pin is pulled low, the corresponding amplifier's output enters high-impedance state with leakage ≤1 nA over −40 °C to +125 °C. The output does not clamp or short - it floats, preserving integrity of downstream circuits like multiplexers or ADC inputs without pull-up/down conflicts.
