Product details
Overview
TSV851ICT from STMicroelectronics is a single-channel, rail-to-rail output, low-power operational amplifier with shutdown capability, designed for precision signal conditioning in space-constrained and battery-sensitive 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 TSV851ICT datasheet, TSV851ICT pinout, TSV851ICT application, or TSV851ICT equivalent, this page provides verified electrical specifications, SC70-5 package layout, shutdown timing behavior, rail-to-rail output drive capability under 2 kΩ load, and validated alternatives for low-voltage, high-accuracy op-amp selection.
Technical Context
The TSV851ICT implements a CMOS input stage with rail-to-rail output swing, supporting input common-mode range from VCC– – 0.2 V to VCC+ – 1 V without phase reversal. Its shutdown pin (SHDN) controls power state with <50 nA quiescent current when pulled low, and turn-on/turn-off times are specified at 300 ns and 20 ns respectively under 2 kΩ load.
It achieves 75 dB typical common-mode rejection ratio (CMRR) and 79 dB supply voltage rejection ratio (SVR) at 25 °C, with input offset voltage drift limited to 1 µV/°C over –40 °C to +125 °C - confirming suitability for uncalibrated automotive temperature sensing and industrial analog front-ends where long-term DC stability is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.3 V to 5.5 V - enables direct operation from single Li-ion cell or 3.3 V/5 V rails without LDO. |
| Gain Bandwidth Product | 1.3 MHz - supports stable unity-gain buffer and active filter designs up to ~100 kHz. |
| Input Offset Voltage | 0.8 mV max at 25 °C - reduces initial calibration burden in precision sensor amplification. |
| Quiescent Current | 180 µA max per channel at 5 V - extends battery life in always-on monitoring nodes. |
| Shutdown Current | 50 nA max at 25 °C - allows microamp-level system sleep mode with fast wake-up (<300 ns). |
| Rail-to-Rail Output Swing | Within 100 mV of rails at 10 kΩ load - maximizes dynamic range in low-voltage ADC driver applications. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
TSV851ICT is packaged in SC70-5 (SOT323-5), a 1.25 mm × 2.0 mm surface-mount package with exposed pad option for thermal enhancement. Pin 1 = IN+, Pin 2 = IN–, Pin 3 = OUT, Pin 4 = VCC–, Pin 5 = SHDN / VCC+ (dual-function pin: tied high for normal operation, low for shutdown).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (IN+) | Non-inverting input node; accepts signals down to VCC– – 0.2 V with no phase reversal. |
| 2 | Inverting Input (IN–) | Inverting input node; matched bias current path with IN+ for low offset error. |
| 3 | Output (OUT) | Rail-to-rail output capable of sourcing/sinking ≥35 mA at 5 V, driving 2 kΩ loads. |
| 4 | Negative Supply (VCC–) | Ground reference or negative rail; must be connected for proper biasing and shutdown function. |
| 5 | Shutdown / Positive Supply (SHDN/VCC+) | Dual-function terminal: pulled high to VCC+ enables amplifier; pulled low to VCC– disables it and places OUT in high-Z state. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown mode | Reduces supply current to ≤50 nA, enabling ultra-low-power system sleep states without external switches. |
| Automotive qualification | AEC-Q100 Grade 1 compliance ensures reliability in engine control units and ADAS sensor interfaces. |
| High ESD tolerance | 4 kV HBM on all pins except SHDN (3.5 kV), reducing susceptibility to handling damage in production lines. |
| Rail-to-rail output with low output impedance | Delivers full-swing signal integrity into 2 kΩ loads while maintaining <100 mV headroom at both rails. |
| Extended temperature performance | Guaranteed 0.8 mV max Vio and 1.3 MHz GBP across –40 °C to +125 °C - no derating required. |
Applications
| Automotive Cabin Temperature Sensor Interface | Portable ECG Front-End Amplifier |
|---|---|
|
Use Scenario: Amplifying thermistor or RTD signals in HVAC control modules mounted near vehicle cabin air ducts. IC Role / Device Role / Timing Role: Precision DC-coupled gain stage with rail-to-rail output driving 12-bit SAR ADC inputs. Use Value: 0.8 mV max Vio and 1 µV/°C drift minimize calibration frequency; shutdown mode cuts standby current to 50 nA during ignition-off periods. |
Use Scenario: Low-noise, low-power instrumentation amplifier first stage in handheld electrocardiogram devices. IC Role / Device Role / Timing Role: Single-supply, rail-to-rail op-amp configured as non-inverting amplifier with gain = 100 for millivolt-level biopotential signals. Use Value: 180 µA quiescent current extends battery life; 30 nV/√Hz input noise at 1 kHz preserves ECG signal fidelity without cooling or shielding. |
| Smart Smoke Detector Signal Conditioning | Industrial 4–20 mA Loop Receiver |
|
Use Scenario: Amplifying photoelectric chamber output in battery-powered residential smoke alarms with 10-year lifespan requirement. IC Role / Device Role / Timing Role: Low-drift transimpedance amplifier converting photodiode current to voltage, followed by filtering and threshold detection. Use Value: 125 °C max operating temperature supports placement near heat-generating alarm electronics; shutdown mode eliminates leakage paths during deep sleep. |
Use Scenario: Converting 4–20 mA loop current to 0.5–2.5 V for microcontroller ADC sampling in programmable logic controller (PLC) I/O modules. IC Role / Device Role / Timing Role: Precision current-to-voltage converter with 250 Ω sense resistor, powered from isolated 3.3 V supply. Use Value: 75 dB CMRR rejects common-mode noise from shared ground returns; 2.3 V min supply allows operation directly from buck converter output without LDO. |
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 |
|---|---|---|---|
| TSV851ILT | Same die, SC70-5 package but without shutdown pin; fixed VCC+ connection at Pin 5. | No power-gating capability; simpler routing but higher system-level standby current. | Select when shutdown functionality is unnecessary and board space is not constrained. |
| MCP6001T-E/OT | 1 µA max supply current, 1 MHz GBP, 2 mV max Vio, no shutdown, SOT23-5 package. | Higher offset and lower bandwidth limit accuracy in precision sensor apps; lacks automotive qualification. | Choose for cost-sensitive consumer applications where AEC-Q100 and sub-mV offset are not required. |
Compared with TSV851ICT, TSV851ILT removes shutdown control to reduce pin count and cost, while MCP6001T-E/OT trades automotive robustness and DC precision for broader availability and lower unit price - making TSV851ICT optimal for safety-critical, battery-limited, or high-accuracy embedded systems.

FAQ
What is the maximum capacitive load the TSV851ICT can drive stably?
The TSV851ICT maintains ≥60° phase margin with up to 200 pF capacitive load when driving a 50 kΩ resistive load, as confirmed in Figure 9 of the datasheet. For heavier loads (>500 pF), external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve stability in unity-gain configurations.
Can the SHDN pin be left floating?
No - the SHDN pin must never be left floating. Per Section 4.7, it must be actively tied to either VCC+ (to enable operation) or VCC– (to enter shutdown). Floating causes undefined output state and potential increased current consumption due to internal input stage ambiguity.
Does TSV851ICT support dual-supply operation?
Yes - although optimized for single-supply use, TSV851ICT functions with split supplies (e.g., ±2.5 V) as long as total supply voltage remains within 2.3 V to 5.5 V and common-mode input range (VCC– – 0.2 V to VCC+ – 1 V) is respected. Pin 4 becomes VEE and Pin 5 becomes VCC, with SHDN referenced to VEE.
How does input offset voltage change over temperature?
Input offset voltage drift is specified at ≤1 µV/°C over –40 °C to +125 °C (Table 4, ΔVio/ΔT). At 125 °C, total Vio remains ≤2 mV for TSV851A grade - verified by characterization data in Figure 3 and Table 4, ensuring predictable DC error accumulation in closed-loop systems.
