Product details
Overview
TSV6392AILT from STMicroelectronics is a dual rail-to-rail input/output micropower operational amplifier in SOT23-8 package, designed for ultra-low-power signal conditioning at supply voltages as low as 1.5 V. It delivers 2.4 MHz gain bandwidth with only 60 µA quiescent current per amplifier at 5 V, features 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, and integrated shutdown functionality enabling 5 nA standby current. It is used in precision sensor front-ends and battery-powered medical instrumentation where rail-to-rail swing and EMI hardening are critical.
For engineers reviewing the TSV6392AILT datasheet, TSV6392AILT pinout, TSV6392AILT application, or TSV6392AILT equivalent, key selection criteria include its guaranteed 2.4 MHz GBP at 60 µA, -40 °C to 125 °C extended temperature operation, shutdown logic compatibility (VIH = 2 V, VIL = 0.8 V at 5 V), and validated stability for gains ≥ 4 (non-inverting) or ≥ 11 (inverting) with 100 pF load.
Technical Context
The TSV6392AILT employs complementary PMOS/NMOS input stages to achieve true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal, with performance degradation limited to a narrow transition region near VCC+ −0.7 V. Its internal current-source trimming ensures ±17% spread on supply current, directly stabilizing GBP (2.4 MHz typ), slew rate (1.1 V/µs), and large-signal gain (98 dB min).
It is not unity-gain stable and requires minimum closed-loop gain of 4 (non-inverting) or 11 (inverting) for stability with 100 pF capacitive load; shutdown control is active-high (SHDN ≥ 2 V at 5 V), forcing output into high-impedance state with 200 ns turn-on and 20 ns turn-off times under 2 kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - supports single-cell Li-ion, coin-cell, and 3.3 V/5 V systems without level-shifting. |
| Quiescent Current | 60 µA per op amp at 5 V - enables >1-year battery life in always-on wearable sensors. |
| Gain Bandwidth Product | 2.4 MHz typ - allows 10 kHz signal amplification with ≥240× closed-loop gain while maintaining phase margin. |
| Input Offset Voltage | 800 µV max (A version) - reduces DC error to <0.8 mV in 1 V full-scale sensor interfaces. |
| Input Bias Current | 1 pA typ - prevents leakage-induced drift in high-impedance pH or photodiode front-ends. |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses cellular band interference in portable diagnostic devices. |
| Shutdown Current | 5 nA typ - cuts total system standby power to sub-nW levels when amplifiers are idle. |
Pinout & Package
TSV6392AILT is housed in a RoHS-compliant SOT23-8 package (3.0 × 2.8 × 1.3 mm), optimized for space-constrained PCB layouts and thermal dissipation of 105 °C/W junction-to-ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-high logic: ≥2 V enables amplifier; ≤0.8 V disables output (Hi-Z) and reduces ICC to 5 nA. |
| 2 (IN−) | Inverting input | Differential input node with rail-to-rail common-mode range and 1 pA bias current. |
| 3 (IN+) | Non-inverting input | Differential input node with same rail-to-rail range and matching bias current to IN−. |
| 4 (V−) | Negative supply rail | Ground reference for single-supply operation; supports 0 V to 5.5 V VCC range. |
| 5 (OUT1) | Amplifier 1 output | Rail-to-rail output capable of sourcing/sinking 40 mA at 5 V, with 35 mV headroom. |
| 6 (OUT2) | Amplifier 2 output | Independent output with identical rail-to-rail swing and drive capability as OUT1. |
| 7 (V+) | Positive supply rail | Accepts 1.5–5.5 V; decoupling capacitor (10 nF) required adjacent to this pin per layout guidelines. |
| 8 (NC) | No connect | Internally unconnected; must remain floating-no external connection permitted. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input CMR extends 0.1 V beyond rails; output swings within 35 mV of V+ and V− with 10 kΩ load. |
| EMI-hardened architecture | 92 dB rejection at 1.8 GHz enables reliable operation near Bluetooth/Wi-Fi antennas in portable devices. |
| Extended temperature grade | Specified from −40 °C to +125 °C - qualified for under-hood automotive sensors and industrial field transmitters. |
| Ultra-low input bias current | 1 pA typ eliminates loading error on MΩ-range sensor elements like thermistors or piezoelectric transducers. |
| Stable high-speed operation | 2.4 MHz GBP with 1.1 V/µs slew rate enables accurate amplification of 100 kHz pulse waveforms in ECG front-ends. |
| Low-noise precision | 60 nV/√Hz input noise at 1 kHz supports microvolt-level signal recovery in EEG and EMG applications. |
Applications
| Portable Medical Sensors | Battery-Powered Data Loggers |
|---|---|

IC Role / Device Role / Timing Role: Precision buffer and anti-aliasing filter driver for 12-bit SAR ADCs sampling at 1 kHz. Use Value: 60 µA per op amp extends battery life to >2 years; shutdown mode reduces quiescent draw to 5 nA during sleep intervals. |
| Industrial Process Transmitters | IoT Edge Node Signal Chains |
|
Use Scenario: Signal conditioning for 4–20 mA loop-powered pressure transducers operating in harsh factory environments. IC Role / Device Role / Timing Role: Rail-to-rail output stage driving ADC reference buffers and isolation amplifier inputs across −40 °C to 125 °C. Use Value: Guaranteed operation at 125 °C eliminates derating; 4 kV HBM ESD rating withstands assembly handling and field ESD events. |
Use Scenario: Active filtering and gain staging for MEMS microphone outputs in voice-controlled smart home hubs. IC Role / Device Role / Timing Role: Low-noise preamplifier (60 nV/√Hz) followed by 2nd-order Sallen-Key filter with 2.4 MHz GBP enabling flat response to 20 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6392IDT | Standard grade (4.5 mV max Vio vs. 0.8 mV), same package and pinout, no A-suffix. | Acceptable for non-precision applications like generic voltage followers or comparator hysteresis circuits. | Select when offset-critical DC accuracy is unnecessary and cost sensitivity outweighs 5× higher Vio. |
| MCP6002T-I/SN | Lower GBP (1 MHz), higher Vio (1.5 mV), no shutdown, SO-8 only - lacks EMI hardening and extended temp grade. | Suitable for basic consumer-grade sensor buffering where RF immunity and 125 °C operation are not required. | Choose only if design already uses SO-8 footprint and operates strictly within 0–70 °C commercial range. |
Compared with TSV6392IDT, the TSV6392AILT provides 5× lower offset for precision DC-coupled paths; versus MCP6002T-I/SN, it adds shutdown control, EMI resilience, and automotive-grade temperature support - critical for certified medical and industrial deployments.

FAQ
What is the minimum stable gain configuration for TSV6392AILT with a 100 pF capacitive load?
The TSV6392AILT requires minimum closed-loop gain of 4 in non-inverting configuration or 11 in inverting configuration when driving a 100 pF load, as verified by phase margin ≥60° testing per DS6635 Rev 4. Using lower gains risks oscillation; for unity-gain stability, ST recommends the TSV63x family instead.
Can TSV6392AILT operate reliably at 1.5 V supply voltage?
Yes - the device is fully characterized and specified down to 1.5 V, with confirmed 2.4 MHz GBP, 60 µA supply current, and rail-to-rail I/O performance at this voltage. Electrical characteristics tables in DS6635 include data at 1.5 V, and Figure 5 shows stable closed-loop response at VCC = 1.5 V.
How does the shutdown function affect output state and timing?
When SHDN is pulled low (≤0.8 V at 5 V), both amplifiers disable and their outputs enter high-impedance state with ≤1 nA leakage. Turn-on time is 200 ns (to 200 mV swing), turn-off time is 20 ns (to 200 mV swing), measured under 2 kΩ load per Figure 23–24 in DS6635 Rev 4.
Is TSV6392AILT pin-compatible with other packages in the TSV639x family?
No - TSV6392AILT uses SOT23-8, while TSV6393A uses MiniSO10 and TSV6394A uses TSSOP14. Pin counts and assignments differ: SOT23-8 has 8 pins (including NC), MiniSO10 has 10 pins, and TSSOP14 has 14 pins. Only same-package variants (e.g., TSV6392IDT) share identical pinout.
