Product details

Overview

TSV854AIPT from STMicroelectronics is a quad-channel, rail-to-rail output operational amplifier with shutdown functionality, designed for precision signal conditioning in automotive and battery-powered systems. It delivers 1.3 MHz gain bandwidth, 0.8 mV max input offset voltage at 25 °C, 180 µA max supply current per channel at 5 V, and operates across -40 °C to +125 °C. Its integrated shutdown pin reduces quiescent current to 50 nA, enabling use in always-on sensor interfaces.

For engineers reviewing the TSV854AIPT datasheet, TSV854AIPT pinout, TSV854AIPT application, or TSV854AIPT equivalent, key selection criteria include rail-to-rail output swing (±180 mV from rails), low-voltage operation (2.3–5.5 V), automotive-grade temperature range, shutdown timing (300 ns turn-on), and ESD robustness (4 kV HBM).

Technical Context

The TSV854AIPT integrates four independent amplifiers with individual shutdown control per pair (SHDN1/2 and SHDN3/4), supporting flexible power management in multi-sensor systems. Its input stage features ground-sensing capability (V_ICM = V_CC- − 0.2 V to V_CC+ − 1 V) and low input bias current (27–60 nA typ), enabling high-impedance source interfacing without phase reversal.

It employs a unity-gain-stable architecture with 60° phase margin and 10 dB gain margin at 200 pF load, ensuring stability in active filtering and transimpedance configurations. The device maintains 90–110 dB large-signal voltage gain over -40 °C to +125 °C and supports rail-to-rail output drive into 2 kΩ loads (±400 mV max saturation error).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.3 V to 5.5 V - Enables direct integration with Li-ion, 3.3 V, and 5 V logic rails without level-shifting.
Gain Bandwidth Product	1.3 MHz - Supports stable closed-loop operation up to ~100 kHz in unity-gain buffer or active filter designs.
Input Offset Voltage	0.8 mV max at 25 °C - Reduces DC error in precision instrumentation without factory calibration.
Supply Current per Channel	180 µA max at 5 V - Enables ultra-low-power operation in multi-amplifier sensor front-ends.
Shutdown Current	50 nA max per channel - Extends battery life in duty-cycled automotive subsystems (e.g., tire pressure sensors).
Rail-to-Rail Output Swing	±180 mV from rails (RL = 10 kΩ) - Maximizes dynamic range in single-supply data acquisition systems.
Operating Temperature	-40 °C to +125 °C - Qualified for under-hood automotive applications and industrial edge nodes.

Pinout & Package

TSV854AIPT is housed in a 14-lead TSSOP package (3.0 mm × 4.4 mm, 0.65 mm pitch) with exposed thermal pad connected to V_CC−. Pin functions are validated per STMicroelectronics DocID022468 Rev 4, Figure 1 (TSSOP14 top view).

Pin/Terminal	Circuit Role	Design Meaning
1, 5, 9, 13	In+ (non-inverting input)	High-impedance input accepting signals down to V_CC− − 0.2 V; enables ground-referenced sensor interfacing.
2, 6, 10, 14	In− (inverting input)	Differential input node; common-mode range extends to V_CC+ − 1 V without phase reversal.
3, 7, 11, 12	Out (output)	Rail-to-rail capable output driving ≥15 mA sink/source; settles within 300 ns after shutdown release.
4	V_CC−	Negative supply rail - reference for shutdown logic and internal biasing; must be tied to system ground in single-supply configs.
8	V_CC+	Positive supply rail - powers all four amplifiers; decoupling capacitor required within 2 mm per layout guidelines.
1&2 (SHDN1/2), 3&4 (SHDN3/4)	Shutdown enable	Active-high logic inputs controlling amplifier pairs; 0.5 V logic low threshold ensures compatibility with 1.8 V/3.3 V microcontrollers.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 1 certified - guaranteed performance in engine control units, ADAS sensors, and body electronics.
ESD robustness	4 kV HBM (all pins except SHDN), 3.5 kV HBM on SHDN - eliminates need for external protection in harsh environments.
Low input offset drift	1 µV/°C max over -40 °C to +125 °C - minimizes thermal-induced error in temperature-sensitive medical or industrial measurements.
Output leakage in shutdown	1 nA max at 125 °C - prevents unintended loading of downstream circuits during sleep mode.
Thermal resistance	R_thJA = 100 °C/W (TSSOP14) - enables reliable operation at full spec without forced airflow in compact enclosures.

Applications

Automotive Cabin Sensors

Battery Management Monitoring

Use Scenario: Signal conditioning for MEMS-based occupancy detection and air quality sensors in vehicle cabins.

IC Role / Device Role / Timing Role: Quad amplifier configures two differential sensor buffers and two active low-pass filters (cutoff ≤10 kHz) before ADC sampling.

Use Value: Rail-to-rail output preserves full 0–3.3 V ADC range; shutdown mode cuts total quiescent current to <200 nA when cabin is unoccupied.

Use Scenario: Precision voltage and current sensing across 12 V lead-acid and 48 V mild-hybrid battery stacks.

IC Role / Device Role / Timing Role: Configured as current-sense amplifiers (gain = 50 V/V) and cell voltage monitors with 0.8 mV offset limiting measurement error to <0.02% FS.

Use Value: Extended temperature range ensures accuracy during cold cranking (-40 °C) and under-hood thermal soak (+125 °C); 1.3 MHz GBP supports fast transient response to load dumps.

Portable Medical Pulse Oximeters

Industrial IoT Edge Nodes

Use Scenario: Analog front-end for red/infrared photodiode signals in wearable pulse oximetry modules.

IC Role / Device Role / Timing Role: Dual-channel transimpedance amplifier (TIA) with programmable gain and second-stage filtering; third/fourth channels condition reference photodiode outputs.

Use Value: Low 30 nV/√Hz input noise at 1 kHz enables SNR >70 dB for weak optical signals; shutdown reduces system standby power by 99.9% between measurements.

Use Scenario: Multi-sensor signal conditioning in wireless vibration and temperature monitoring nodes deployed on motors and pumps.

IC Role / Device Role / Timing Role: Simultaneous amplification of piezoelectric accelerometer outputs, RTD bridge signals, and thermistor voltages using all four channels.

Use Value: Single 3.3 V supply simplifies power architecture; 125 °C rating allows placement near hot motor housings; AEC-Q100 qualification ensures long-term reliability in continuous operation.

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
TSV854IPT	No shutdown pins; identical electrical specs except ICC = 180 µA (no 50 nA shutdown mode)	Lacks power-gating capability; unsuitable for duty-cycled sensor nodes requiring ultra-low sleep current	Select when shutdown is unnecessary and cost optimization is prioritized over power flexibility
LMV854QDGKR	Higher GBP (5.5 MHz), higher ICC (500 µA/ch), no AEC-Q100 qualification, SOIC-14 only	Better for wideband active filters but consumes 2.8× more active current and lacks automotive reliability validation	Choose for non-automotive test equipment needing higher speed, accepting larger board area and higher power budget

Compared with TSV854AIPT, TSV854IPT sacrifices power gating for lower unit cost, while LMV854QDGKR trades automotive qualification and ultra-low shutdown current for bandwidth-making TSV854AIPT optimal for safety-critical, battery-constrained automotive and industrial edge deployments.

FAQ

What is the maximum capacitive load the TSV854AIPT can drive stably?

The TSV854AIPT maintains 60° phase margin with up to 200 pF capacitive load when configured as a unity-gain buffer with 50 kΩ feedback resistor (per Figure 9). For loads exceeding 200 pF, external isolation resistors (≥100 Ω) are required in series with the output to preserve stability, as confirmed in Figures 10–11 of the datasheet.

Can the shutdown pins be left unconnected?

No. The SHDN1/2 and SHDN3/4 pins must never float: they must be actively pulled to V_CC+ (to enable) or V_CC− (to disable) using ≤10 kΩ resistors. Floating shutdown pins cause undefined amplifier state and potential output oscillation, as explicitly warned in Section 4.7 of the datasheet.

Does the TSV854AIPT support dual-supply operation?

Yes. While optimized for single-supply use (2.3–5.5 V), it operates with split supplies (e.g., ±2.5 V) as long as total V_CC+–V_CC− remains within 2.3–5.5 V and absolute pin voltages stay within absolute maximum ratings (Table 2). Input common-mode range extends to V_CC− − 0.2 V, enabling true bipolar signal handling.

How does the input offset voltage change over temperature?

The TSV854AIPT exhibits a maximum input offset voltage drift of 1 µV/°C over -40 °C to +125 °C (Table 4, ΔV_io/ΔT). At 125 °C, total offset remains ≤2 mV (max), making it suitable for applications where thermal drift must stay below 0.05% of full-scale output in 12-bit systems.
