Product details
Overview
TSV6391ILT from STMicroelectronics is a single, rail-to-rail input/output CMOS operational amplifier optimized for micropower, low-voltage operation in precision signal conditioning. It delivers 2.4 MHz gain bandwidth product at 60 µA supply current (5 V), supports 1.5–5.5 V supply range, and operates across –40 °C to 125 °C - enabling use in battery-powered medical sensors and portable instrumentation.
For engineers reviewing the TSV6391ILT datasheet, TSV6391ILT pinout, TSV6391ILT application, or TSV6391ILT equivalent, key selection criteria include its 1 pA typical input bias current, 500 µV max offset voltage (A-version), shutdown-incompatible topology, SC70-5/SOT23-5 package options, and stability at gains ≥4 or ≤–3.
Technical Context
The TSV6391ILT uses complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (VCC– –0.1 V to VCC+ +0.1 V) without phase reversal. Its internal compensation ensures stability at closed-loop gains of ≥4 (non-inverting) or ≤–3 (inverting) with 100 pF load capacitance.
It features no shutdown pin - unlike the TSV6390 series - and relies on continuous biasing for ultra-low 1 pA input bias current and 60 µA quiescent current. Output drive capability reaches ±63 mA at 5 V, with rail-to-rail swing limited to 35 mV from each rail under 10 kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct integration into single-cell Li-ion (3.0–4.2 V), alkaline (1.5 V), or regulated 3.3 V/5 V systems without level-shifting. |
| Gain Bandwidth Product | 2.4 MHz typ. at 5 V - supports audio-band filtering (e.g., 20 kHz anti-aliasing) with >100× loop gain margin at unity gain. |
| Input Bias Current | 1 pA typ. - minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance amps). |
| Offset Voltage (A version) | 500 µV max - ensures ≤0.5 mV DC error in 12-bit ADC front-ends with 2.5 V reference (0.02% FSR error). |
| Output Drive | ±63 mA at VCC = 5 V - drives 80 Ω loads directly (e.g., 50 Ω coax + termination) without external buffer. |
| ESD Rating | 4 kV HBM - meets IEC 61000-4-2 Level 2 for handheld device touchpoints and exposed analog inputs. |
| Operating Temperature | –40 °C to 125 °C - qualified for under-hood automotive sensor nodes and industrial motor control feedback paths. |
Pinout & Package
TSV6391ILT is available in SOT23-5 (5-pin) and SC70-5 (5-pin) packages - both surface-mount, lead-free, RoHS-compliant micropackages with identical pin mapping. The SOT23-5 variant offers higher thermal resistance (250 °C/W) versus SC70-5 (205 °C/W), influencing power dissipation limits in continuous 60 µA operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Inverting Input (–) | Differential input node | Accepts feedback network connection; common-mode range extends to rails - critical for single-supply inverting amplifiers. |
| Non-inverting Input (+) | Differential input node | Connects to reference or sensor; rail-to-rail input allows direct interfacing with 0–VCC sensor outputs (e.g., resistive bridge midpoints). |
| Output | Amplified signal source | Rail-to-rail swing (≤35 mV from rails) enables full utilization of 12-bit ADC input range in 3.3 V systems. |
| VCC+ | Positive supply rail | Must be decoupled with 10 nF capacitor placed ≤2 mm from pin - required to suppress 2.4 MHz GBW-induced supply noise coupling. |
| VCC– | Negative supply rail / ground | Serves as return path for 60 µA quiescent current and output sink/source current; low-impedance grounding essential for THD & noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal handling in single-supply systems (e.g., 0–3.3 V) without level-shifting circuitry or dual supplies. |
| 60 µA supply current at 5 V | Extends coin-cell battery life to >10 years in always-on sensor nodes drawing <1 µA average (with duty-cycled sampling). |
| 2.4 MHz gain bandwidth at 60 µA | Delivers 40× higher speed per µA than legacy micropower op-amps (e.g., LMV321), enabling faster settling in data acquisition front-ends. |
| 1 pA typical input bias current | Reduces leakage-induced offset drift in high-Z transducer interfaces (e.g., piezoelectric accelerometers, capacitive humidity sensors). |
| Stable at gain ≥4 or ≤–3 | Eliminates need for external compensation in standard active filter topologies (e.g., Sallen-Key low-pass, multiple-feedback band-pass). |
Applications
| Portable ECG Monitor Front-End | Smart Gas Sensor Signal Chain |
|---|---|

Use Scenario: Amplifying microvolt-level biopotential signals from dry electrodes in battery-powered wearable ECG devices. IC Role / Device Role / Timing Role: Primary gain stage in 3-stage analog front-end, providing 100× non-inverting amplification before 12-bit SAR ADC sampling at 1 kHz. Use Value: 1 pA input bias current prevents electrode polarization errors; rail-to-rail output ensures full 0–3.3 V ADC range utilization without clipping. |
Use Scenario: Conditioning ppm-level analog output from electrochemical CO sensors in IoT air quality nodes. IC Role / Device Role / Timing Role: Transimpedance amplifier converting sensor current (0–200 nA) to voltage, followed by 2nd-order active low-pass filtering (fc = 10 Hz).

| Industrial Temperature Transmitter | USB-C Power Delivery Monitor |
|
Use Scenario: Amplifying RTD bridge output in DIN-rail-mounted temperature transmitters operating in harsh factory environments. IC Role / Device Role / Timing Role: Precision instrumentation amplifier input stage, rejecting common-mode noise from 24 V DC field wiring while maintaining 0.1 °C resolution. Use Value: –40 °C to 125 °C rating ensures reliability in uncooled enclosures; 4 kV HBM ESD withstand protects against installation-related static discharge. |
Use Scenario: Monitoring CC line voltage during USB-C power negotiation in portable chargers and power banks. IC Role / Device Role / Timing Role: Level translator and comparator input buffer, scaling 0–5 V CC signaling to 0–1.8 V logic thresholds for MCU GPIO detection. Use Value: 1.5 V minimum supply allows direct operation from USB-C VCONN (up to 5 V); rail-to-rail input captures full CC voltage swing without clipping. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6391AICT | Same die, SC70-5 package; 500 µV max offset (vs. 3 mV for non-A version), identical 60 µA/2.4 MHz specs. | Preferred where <0.5 mV DC error is mandatory (e.g., medical calibration circuits), but requires re-layout for smaller SC70 footprint. | Select when offset-critical precision outweighs PCB area constraints; same thermal and electrical behavior otherwise. |
| MCP6001T-I/OT | Lower GBP (1 MHz), higher ICC (100 µA), wider offset range (1.5 mV max), but unity-gain stable and includes shutdown. | Suitable for general-purpose low-speed buffering where stability at G = 1 is required, but not for 2.4 MHz active filters. | Choose only if unity-gain operation or shutdown functionality is needed - trade-off is 2.4× higher current and 2.4× lower bandwidth. |
Compared with TSV6391ILT, the TSV6391AICT delivers guaranteed low-offset performance in the same package form factor, while the MCP6001T-I/OT sacrifices bandwidth and efficiency for broader gain flexibility and integrated shutdown - making it unsuitable for high-speed, ultra-low-power precision roles.

FAQ
Does TSV6391ILT have a shutdown pin?
No. The TSV6391ILT lacks a shutdown function - unlike the TSV6390 series, which includes an SHDN pin. It operates continuously when powered. For power-gated applications, external MOSFET switching of VCC or use of the pin-compatible TSV6390ILT is required.
What is the minimum stable gain configuration for TSV6391ILT?
The TSV6391ILT is stable at non-inverting gains ≥4 or inverting gains ≤–3 when driving 100 pF capacitive loads. Attempting unity-gain or G = 2 configurations risks oscillation; for such cases, ST recommends the unity-gain-stable TSV6291 or TSV6301 instead.
Can TSV6391ILT drive a 50 Ω load directly?
Yes - at 5 V supply, it delivers ±63 mA output current, sufficient to drive a 50 Ω load to ±2.5 V (50 mA) with headroom. However, THD increases significantly below 2 kΩ; for clean 50 Ω driving, verify distortion at target frequency using Figure 2/3 from the datasheet.
Is TSV6391ILT compatible with SC70-5 and SOT23-5 footprints?
Yes - both SC70-5 and SOT23-5 packages share identical 5-pin pinout (IN+, IN–, OUT, V–, V+) and compatible land patterns per ST's recommended footprints (Figures 22 and 23). Mechanical differences (size, thermal resistance) require layout review but no schematic change.
