Product details
Overview
TSV851ILT from STMicroelectronics is a single-channel, rail-to-rail output, low-power operational amplifier with shutdown functionality, designed for precision signal conditioning in space-constrained, 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 - enabling use in automotive sensor front-ends and portable medical monitors.
For engineers reviewing the TSV851ILT datasheet, TSV851ILT pinout, TSV851ILT application, or TSV851ILT equivalent, key selection considerations include its 50 nA shutdown current, SC70-5 package footprint, rail-to-rail output swing (≤180 mV from rails), and guaranteed performance over extended temperature and low-voltage (2.3–5.5 V) operation.
Technical Context
The TSV851ILT integrates a precision CMOS input stage with rail-to-rail output capability and an active shutdown control pin (SHDN), enabling fast turn-on (<300 ns) and turn-off (<20 ns) transitions while maintaining high common-mode rejection (72 dB min) and supply voltage rejection (72 dB min). Its architecture supports stable operation with capacitive loads up to 200 pF without external compensation.
It features an input common-mode range extending from VCC− −0.2 V to VCC+ −1 V (including ground), enabling direct interfacing with single-supply sensors and ADCs. The device's 1 μV/°C max input offset drift and 0.6–0.7 V/μs slew rate support accurate DC-coupled amplification and moderate-speed signal conditioning in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.3 V to 5.5 V - enables direct integration into Li-ion (3.0–4.2 V) and dual-cell alkaline (2.4–3.2 V) powered systems without LDO pre-regulation. |
| Gain Bandwidth Product | 1.3 MHz - supports closed-loop gains up to ~13 at 100 kHz, suitable for anti-aliasing filters and sensor gain stages. |
| Input Offset Voltage | 0.8 mV max at 25 °C - reduces DC error in precision transducer interfaces without factory trimming or software calibration. |
| Supply Current per Channel | 180 µA max at 5 V - extends battery life in always-on wearable sensors (e.g., >5-year runtime on CR2032). |
| Shutdown Current | 50 nA max at 25 °C - allows ultra-low-power duty-cycled operation in intermittent-sampling applications like environmental data loggers. |
| Rail-to-Rail Output Swing | ≤180 mV from rails (RL = 10 kΩ) - maximizes dynamic range when driving 12-bit SAR ADCs with 0–VCC input range. |
| Operating Temperature | -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood automotive signal conditioning. |
Pinout & Package
The TSV851ILT 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 PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | Accepts input signals down to VCC− −0.2 V; compatible with ground-referenced sensors and resistive bridges. |
| 2 (IN−) | Inverting input | Differential input node; supports unity-gain stable configurations including inverting amplifiers and active filters. |
| 3 (OUT) | Amplifier output | Rail-to-rail capable; drives 10 kΩ loads to within 180 mV of VCC+ or VCC−; high-Z in shutdown mode. |
| 4 (VCC−) | Negative supply | Ground reference for single-supply operation; must be connected directly to system GND plane. |
| 5 (SHDN) | Shutdown control | Active-low logic input; pulls to VCC− to disable amplifier and reduce ICC to ≤50 nA; must not float. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown mode | Reduces quiescent current to 50 nA max, enabling microamp-level system sleep states in battery-backed devices. |
| Extended temperature operation | Guaranteed performance from -40 °C to +125 °C supports placement near powertrain ECUs or industrial motor controllers. |
| Rail-to-rail output swing | Delivers full-scale output headroom with 2.3 V minimum supply, critical for low-voltage ADC interfacing in portable diagnostics. |
| Enhanced input offset accuracy | 0.8 mV max offset at 25 °C and 2 mV max over full temperature range improves measurement fidelity in strain gauge and thermistor circuits. |
| High ESD tolerance | 4 kV HBM (non-SHDN pins) and 1.3 kV CDM robustness simplify board-level ESD protection design in automotive assembly lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV851IDT | Same electrical specs but in SO8 package (4.9 × 6.0 mm); no shutdown pin; higher thermal resistance (125 °C/W vs. 205 °C/W). | Lacks shutdown function; suited for fixed-power, non-battery applications where board area is less constrained. | Select when shutdown is unnecessary and SO8 hand-solderability or legacy footprint compatibility is required. |
| LMV321IDBVR | Higher supply current (130 µA typ), wider offset voltage spec (3 mV max), lower GBP (1 MHz), no shutdown, rated only to 85 °C. | Not qualified for automotive or extended-temp industrial use; limited to consumer-grade portable electronics. | Choose only for cost-sensitive, non-automotive designs where 125 °C operation and sub-1 mV offset are not required. |
Compared with TSV851IDT, the TSV851ILT trades larger SO8 footprint for SC70-5 miniaturization and adds shutdown control; versus LMV321IDBVR, it delivers tighter offset, lower power, broader temperature range, and automotive qualification - making it the sole choice for AEC-Q100-compliant, space-limited, battery-aware systems.

FAQ
What is the maximum capacitive load the TSV851ILT can drive stably?
The TSV851ILT maintains stability with capacitive loads up to 200 pF when driving a 10 kΩ resistive load, as verified by phase margin ≥60° across -40 °C to +125 °C. For loads >200 pF, external isolation resistor (≥100 Ω) between output and capacitor is recommended to prevent peaking or oscillation.
Does the SHDN pin require a pull-up resistor?
No - the SHDN pin is CMOS-compatible and internally biased; it must be driven actively high (to VCC+) or low (to VCC−) and never left floating. A weak external pull-up is unnecessary and may increase leakage; direct connection to GPIO or logic net is preferred for reliable shutdown control.
Can the TSV851ILT operate from a 2.3 V supply while maintaining rail-to-rail output?
Yes - the datasheet guarantees rail-to-rail output swing (≤180 mV from rails) at 2.3 V supply with RL = 10 kΩ, confirmed across -40 °C to +125 °C. This enables direct interface with 2.5 V or 3.3 V ADCs in ultra-low-voltage systems without level-shifting circuitry.
Is the TSV851ILT pin-compatible with other SC70-5 op-amps like the TSZ121ILT?
No - the TSV851ILT uses a non-standard SC70-5 pinout: Pin 1 = IN+, Pin 2 = IN−, Pin 3 = OUT, Pin 4 = VCC−, Pin 5 = SHDN. TSZ121ILT (and most SC70-5 op-amps) follow standard pinout (Pin 1 = OUT, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = VCC−, Pin 5 = VCC+), making them electrically and physically incompatible without PCB redesign.
