Product details

Overview

TSV850ILT from STMicroelectronics is a single-channel, rail-to-rail output operational amplifier with shutdown control, designed for precision signal conditioning in low-voltage, power-constrained 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 from 2.3 V to 5.5 V across –40 °C to +125 °C - enabling use in automotive sensor front-ends and portable medical monitors.

For engineers reviewing the TSV850ILT datasheet, TSV850ILT pinout, TSV850ILT application, or TSV850ILT equivalent, key selection criteria include its 50 nA shutdown current, rail-to-rail output swing (≤180 mV from rails), enhanced input offset voltage vs. LMV321, automotive qualification (AEC-Q100), and SC70-5 package compatibility with space-limited PCB layouts.

Technical Context

The TSV850ILT implements a CMOS input stage with rail-to-rail output stage, supporting common-mode input range from V_CC– – 0.2 V to V_CC+ – 1 V and output swing within 100 mV of each rail under light load. Its shutdown pin (SHDN) controls enable/disable state with logic-compatible thresholds (V_IL ≤ 0.5 V, V_IH ≥ V_CC– – 0.5 V) and guarantees <50 nA quiescent current when asserted.

It features 1.3 MHz GBP, 0.6–0.7 V/µs slew rate, and 70–75 dB CMRR over temperature, optimized for unity-gain stable operation with capacitive loads up to 200 pF. Input offset drift is specified at 1 µV/°C, and ESD tolerance reaches 4 kV HBM (3.5 kV on SHDN), supporting robust deployment in automotive and industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.3 V to 5.5 V - supports direct connection to Li-ion battery (3.0–4.2 V) or 3.3 V/5 V rails without level-shifting.
Gain Bandwidth Product	1.3 MHz - enables stable closed-loop operation up to ~100 kHz in unity-gain buffer or active filter configurations.
Input Offset Voltage	0.8 mV max at 25 °C - reduces DC error in precision transducer amplification without trimming.
Supply Current per Channel	180 µA max at 5 V - extends battery life in always-on sensor nodes (e.g., >10-year runtime on CR2032).
Shutdown Current	50 nA max at 25 °C - cuts power during idle cycles in duty-cycled measurement systems.
Rail-to-Rail Output Swing	≤100 mV from V_CC+ and V_CC– at 10 kΩ load - maximizes dynamic range in low-voltage ADC driver stages.
Operating Temperature	–40 °C to +125 °C - validated for under-hood automotive and industrial motor control ambient conditions.

Pinout & Package

TSV850ILT is housed in a 5-pin SC70-5 (SOT323-5) package - a 2.0 mm × 1.25 mm surface-mount outline with 0.65 mm pitch, optimized for high-density PCBs in portable and automotive modules.

Pin	Circuit Role	Design Meaning
1	In+	Non-inverting input - accepts signals down to V_CC– – 0.2 V, enabling ground-referenced sensor interfacing.
2	In−	Inverting input - differential pair input node; matched to In+ for low input offset and bias current.
3	Out	Amplifier output - rail-to-rail capable, drives 10 kΩ loads to within 100 mV of supply rails.
4	V_CC–	Negative supply terminal - connects to ground or negative rail; reference for shutdown and input common-mode range.
5	SHDN	Active-low shutdown control - pulls low to disable amplifier and reduce supply current to ≤50 nA.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q100 Grade 1 - qualified for engine control units, body electronics, and ADAS sensor interfaces.
ESD robustness	4 kV HBM (3.5 kV on SHDN pin) - eliminates need for external protection in harsh assembly environments.
Input offset drift	1 µV/°C - ensures <1.2 mV total offset shift over –40 °C to +125 °C, critical for uncalibrated medical sensors.
Turn-on/off time	300 ns turn-on, 20 ns turn-off - enables microsecond-scale power gating in synchronized data acquisition systems.
Output leakage in shutdown	1 nA max at 125 °C - prevents signal corruption in high-impedance feedback networks during sleep mode.

Equivalent & Alternatives

The following parts are listed as comparable options for similar operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LMV321IDBVR	No shutdown function; higher V_os (2.5 mV max); lower GBP (1 MHz); wider supply range (2.7–5.5 V)	Lacks power-gating capability; less suitable for duty-cycled sensor nodes	Select when shutdown is unnecessary and cost sensitivity outweighs precision requirements
TSV851ILT	No shutdown pin; identical V_os, GBP, and supply specs; same SC70-5 package	Drop-in replacement where system-level shutdown is handled externally	Choose for simplified layout when board-level enable control already exists

Compared with LMV321IDBVR, TSV850ILT offers tighter offset, higher bandwidth, and integrated shutdown - critical for automotive and battery-powered precision apps; versus TSV851ILT, it adds SHDN functionality at no penalty to accuracy or speed, making it optimal when dynamic power control is required.

FAQ

What is the maximum capacitive load the TSV850ILT can drive stably?

The TSV850ILT maintains stability with capacitive loads up to 200 pF when configured as a unity-gain buffer, as verified by phase margin ≥60° and gain margin ≥10 dB per datasheet Figure 11. For loads exceeding 200 pF, an isolation resistor (≥100 Ω) between output and capacitance is recommended to preserve stability without degrading bandwidth significantly.

Does the SHDN pin require a pull-up resistor, and what value is recommended?

Yes - the SHDN pin must not float and requires a defined logic state. A 100 kΩ pull-up to V_CC+ is recommended for reliable enablement; this draws only 50 nA additional current while ensuring fast, noise-immune activation. Internal SHDN input current is ≤10 pA, so higher values (up to 1 MΩ) remain viable in low-noise designs.

Can the TSV850ILT operate with a single 2.3 V supply and still achieve rail-to-rail output?

Yes - the device is fully specified down to 2.3 V supply, and its rail-to-rail output stage delivers swing within 180 mV of both rails (V_CC+ and V_CC–) at 10 kΩ load, even at minimum supply. Output voltage compliance is maintained across the full –40 °C to +125 °C range, enabling use in ultra-low-voltage energy-harvesting systems.

How does the input common-mode range support ground-referenced sensor interfacing?

The input common-mode range extends to V_CC– – 0.2 V, allowing direct connection of grounded sensors (e.g., thermistors, bridge transducers) without level-shifting circuitry. This eliminates offset errors and component count in single-supply systems, while maintaining guaranteed performance - including no phase reversal - across the full specified input range.
