Product details
Overview
TSV854IDT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier with shutdown capability, designed for precision signal conditioning in space-constrained, low-power systems. 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 - enabling use in automotive sensor front-ends and portable medical monitors.
For engineers reviewing the TSV854IDT datasheet, TSV854IDT pinout, TSV854IDT application, or TSV854IDT equivalent, key selection considerations include its dual-rail operation (2.3–5.5 V), 50 nA shutdown current, ±1 μV/°C offset drift, and SO14/TSSOP14 package compatibility with high-density PCB layouts.
Technical Context
The TSV854IDT integrates four independent op-amps with individual shutdown control (SHDN1–SHDN4), supporting selective channel power gating. Its input stage features extended common-mode range (VCC− − 0.2 V to VCC+ − 1 V) and rail-to-rail output swing (≤100 mV from rails at 10 kΩ load).
It employs a CMOS input architecture delivering 0.5–30 nA input offset current and 70–75 dB common-mode rejection over temperature, with stable unity-gain operation up to 1.3 MHz and 60° phase margin into 200 pF capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.3 V to 5.5 V - enables direct interface with Li-ion battery (3.0–4.2 V) and 3.3 V/5 V logic domains without level shifting. |
| Gain Bandwidth Product | 1.3 MHz - supports stable closed-loop amplification of DC–100 kHz signals (e.g., ECG, pressure transducer outputs) with ≤1% gain error. |
| Input Offset Voltage | 0.8 mV max at 25 °C - reduces initial calibration burden in 12-bit ADC front-ends (e.g., <0.2 LSB error at 3.3 V full scale). |
| Supply Current per Channel | 180 µA max at 5 V - allows four-channel operation at <720 µA total, critical for multi-sensor nodes in wireless IoT edge devices. |
| Shutdown Current | 50 nA max per channel - extends battery life by >100× vs active mode in intermittent-sampling applications (e.g., periodic temperature logging). |
| Operating Temperature | -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood automotive signal conditioning (e.g., throttle position sensing). |
| Output Drive Capability | ±35 mA sink/source at 5 V - drives 2 kΩ loads directly (e.g., driving ADC reference buffers or analog multiplexer inputs) without external gain stages. |
Pinout & Package
TSV854IDT is packaged in SO14 (small outline integrated circuit, 14-pin, 3.9 mm × 8.75 mm body, 1.27 mm pitch) with exposed pad not present - suitable for standard reflow assembly and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | In+ (non-inverting input) | High-impedance CMOS input accepting signals from resistive sensors or DAC outputs without loading. |
| 2, 6, 10, 13 | In− (inverting input) | Supports precision differential configurations (e.g., instrumentation amp feedback networks) with matched internal layout. |
| 3, 7, 11, 14 | Out (output) | Rail-to-rail output capable of sourcing/sinking ≥35 mA - eliminates need for external buffer in drive-heavy analog stages. |
| 4 | VCC− (negative supply) | Ground-referenced return path; accepts 0 V or negative bias (e.g., dual-supply ±2.5 V operation). |
| 8 | VCC+ (positive supply) | Accepts 2.3–5.5 V - powers all four channels and internal bias circuits; requires local 10 nF decoupling. |
| 15, 16 | SHDN1/2, SHDN3/4 | CMOS-compatible enable pins: pulled high → active; pulled to VCC− → 50 nA shutdown per pair - enables per-group power management. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel with independent shutdown | Two dedicated shutdown pins (SHDN1/2 and SHDN3/4) allow grouped channel disable - reducing system-level standby power without firmware overhead. |
| Rail-to-rail output swing | Output reaches within 100 mV of VCC+ and VCC− at 10 kΩ load - maximizes dynamic range when interfacing with 12-bit SAR ADCs operating on same supply. |
| Low input offset drift | 1 μV/°C max over −40 °C to +125 °C - ensures <1.2 mV total offset shift across automotive temperature range, eliminating recalibration in engine control units. |
| Automotive qualification | AEC-Q100 qualified with 4 kV HBM ESD rating - validated for harsh environments including engine compartments and ADAS sensor modules. |
| Extended common-mode range | Inputs operate down to VCC− − 0.2 V - supports single-supply sensing of ground-referenced signals (e.g., thermistor bridges) without level-shifting circuitry. |
Applications
| Automotive Sensor Signal Conditioning | Portable Medical Instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV854AIDT | Enhanced input offset voltage (0.8 mV max vs. 4 mV max for TSV854IDT) and lower offset drift (1 μV/°C vs. 2 μV/°C). | Better suited for high-precision DC-coupled applications like strain gauge bridges where initial offset dominates error budget. | Select TSV854AIDT when <1 mV total offset is required across temperature; otherwise TSV854IDT offers cost advantage with identical pinout and shutdown functionality. |
| LMV324DT | Higher supply current (250 µA/channel), no shutdown feature, wider offset range (7 mV max), and lower GBP (1 MHz). | Limited to non-battery-critical, cost-sensitive industrial controls where power gating and precision are secondary. | Choose LMV324DT only if legacy design reuse or BOM consolidation outweighs 30% higher quiescent power and missing shutdown capability. |
Compared with TSV854AIDT, the TSV854IDT trades 3.2 mV higher typical offset for broader availability and lower unit cost; versus LMV324DT, it adds shutdown control, 30% lower power, and 30% higher bandwidth - making it optimal for new energy-conscious designs requiring channel-level power management.

FAQ
What is the maximum capacitive load the TSV854IDT can drive stably?
The TSV854IDT maintains stability with up to 200 pF capacitive load while delivering 60° phase margin and 10 dB gain margin at 5 V supply. Driving larger loads (e.g., >500 pF) requires isolation resistance (≥100 Ω) between output and capacitance to prevent peaking or oscillation - verified in Figure 11 of the datasheet.
Can the SHDN pins be tied together and controlled by a single microcontroller GPIO?
Yes - SHDN1/2 and SHDN3/4 are electrically isolated but share identical logic thresholds (VIH = VCC− + 0.5 V, VIL = 0.5 V). Connecting both to one GPIO enables synchronized shutdown of all four channels, reducing MCU pin count; however, independent control requires two separate GPIOs.
Does the TSV854IDT support dual-supply operation?
Yes - the device operates with split supplies (e.g., ±2.5 V) as long as total VCC+ to VCC− difference remains within 2.3–5.5 V and absolute pin voltages stay within absolute maximum ratings (e.g., input pins between VCC− − 0.3 V and VCC+ + 0.3 V). Common-mode range extends to VCC− − 0.2 V.
How does the input offset voltage change over temperature for the TSV854IDT?
The TSV854IDT exhibits a maximum input offset voltage drift of 2 μV/°C across −40 °C to +125 °C (per Table 4), resulting in ≤340 μV additional offset shift over the full range. This is confirmed by measured ΔVio/ΔT values in the electrical characteristics section and supports drift-critical applications like precision thermocouple amplifiers.
