Product details
Overview
TSV6392AIST from STMicroelectronics is a dual rail-to-rail input/output micropower operational amplifier in MiniSO8 package, delivering 2.4 MHz gain bandwidth at 60 µA supply current (5 V), 800 µV max offset voltage (A-grade), and shutdown capability with 5 nA quiescent current. It operates from 1.5 V to 5.5 V and supports extended temperature range (–40 °C to +125 °C), making it ideal for precision sensor signal conditioning in battery-powered medical wearables.
For engineers reviewing the TSV6392AIST datasheet, TSV6392AIST pinout, TSV6392AIST application, or TSV6392AIST equivalent, key selection criteria include its guaranteed A-grade offset (≤800 µV), EMI-hardened architecture (EMIRR up to 92 dB at 1.8 GHz), ultra-low 1 pA input bias current, and stable operation down to 1.5 V - critical for low-voltage analog front-ends in portable diagnostics and IoT edge nodes.
Technical Context
The TSV6392AIST employs complementary PMOS/NMOS input stages enabling true rail-to-rail input (VICM = VCC– – 0.1 V to VCC+ + 0.1 V) and output swing within 35 mV of rails under 10 kΩ load. Its internal current-starved compensation ensures stability at gains ≥4 (non-inverting) or ≥–3 (inverting), with phase margin ≥60° at 100 pF load.
It integrates a dedicated SHDN pin that places outputs in high-impedance state and reduces total supply current to ≤1.5 µA over full temperature range. The device's EMI rejection ratio (EMIRR) exceeds 61 dB at 400 MHz and peaks at 92 dB at 1.8 GHz, validated per IEC 61000-4-3, confirming hardening against cellular and Wi-Fi interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct interface with single-cell Li-ion (3.0–4.2 V), alkaline (1.5 V), and LDO-regulated 3.3 V/1.8 V systems without level shifting. |
| Gain Bandwidth Product | 2.4 MHz typ at 5 V - supports closed-loop bandwidths >200 kHz with gain = 10, suitable for anti-aliasing filters and fast sensor amplification. |
| Input Offset Voltage | 800 µV max (A version) - ensures ≤0.8 mV error in 1 V full-scale measurements, critical for 12-bit+ precision in medical ADC front-ends. |
| Quiescent Current | 60 µA typ per op amp at 5 V - allows two-channel operation for <120 µA total, extending battery life beyond 1 year in 10 µA sleep-cycle devices. |
| Shutdown Current | 5 nA typ - reduces system standby power to negligible levels, essential for always-on health monitors with periodic wake-up sampling. |
| Input Bias Current | 1 pA typ - minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoresistive sensors >100 MΩ). |
| EMI Rejection Ratio | 92 dB at 1.8 GHz - suppresses RF rectification artifacts in noisy environments (e.g., near Bluetooth/Wi-Fi transceivers), preventing DC offset shifts. |
Pinout & Package
TSV6392AIST is housed in an 8-pin MiniSO8 (SO8-compatible) surface-mount package with exposed pad for thermal enhancement (RthJA = 190 °C/W). Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise orientation when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Drives loads down to 35 mV from rails; requires 10 nF local decoupling on VCC to maintain stability with capacitive loads. |
| 2 (–IN1) | Channel 1 inverting input | Accepts common-mode voltages from VCC– – 0.1 V to VCC+ + 0.1 V; 1 pA bias current avoids loading high-Z sensors. |
| 3 (+IN1) | Channel 1 non-inverting input | Same rail-to-rail CM range as Pin 2; differential input voltage limited to ±VCC per absolute maximum rating. |
| 4 (VCC–) | Negative supply / ground | Reference node for both channels; must be connected directly to low-impedance ground plane to minimize noise coupling. |
| 5 (+IN2) | Channel 2 non-inverting input | Independent input stage; shares same CM range and bias current spec as Pin 3. |
| 6 (–IN2) | Channel 2 inverting input | Matches Pin 2 performance; differential pair transition occurs at VCC+ – 0.7 V, causing minor CMR degradation in that region. |
| 7 (OUT2) | Channel 2 output | Identical drive capability to Pin 1; slew rate 1.1 V/µs at 5 V enables 100 kHz sine wave generation at 1 VPP. |
| 8 (SHDN) | Shutdown control | Active-high logic: ≥2 V (at 5 V supply) enables both amps; ≤0.8 V disables them and forces outputs to high-Z state. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems (e.g., 1.8 V microcontroller ADC reference), eliminating need for level-shifting circuitry. |
| A-grade precision (800 µV max VIO) | Reduces calibration overhead in factory-trimmed medical sensors; eliminates post-assembly offset trimming for Class IIa wearable devices. |
| EMI-hardened architecture | Prevents RF-induced DC errors in proximity to 2.4 GHz ISM band transceivers - verified via IEC 61000-4-3 testing at 10 V/m field strength. |
| Ultra-low 1 pA input bias current | Preserves signal integrity from high-impedance biopotential electrodes (e.g., ECG dry electrodes >1 GΩ), avoiding baseline drift. |
| 5 nA shutdown current | Allows integration into energy-harvesting systems where average power budget is sub-µW; turn-on time <200 ns supports burst-mode sensing. |
Applications
| Portable ECG Monitor | Wireless Glucose Sensor |

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 | No A-grade offset spec (max 3 mV vs. 0.8 mV); no shutdown pin; SOT23-8 package (smaller footprint, higher RthJA = 105 °C/W). | Suitable for cost-sensitive consumer wearables where offset calibration is performed in firmware and space constraints favor SOT23-8. | Select when PCB area is critical and offset tolerance >3 mV is acceptable; avoid in medical-grade uncalibrated analog paths. |
| MCP6002T-I/SN | Lower GBP (1 MHz), higher VIO (1.5 mV max), no EMI hardening, but unity-gain stable and wider supply range (1.8–6.0 V). | Better for general-purpose low-speed buffering where RF immunity is not required and gain <10 dominates design. | Choose for non-critical industrial controls or educational kits; reject for battery-powered medical or wireless-sensor applications demanding RF robustness. |
Compared with TSV6392IDT and MCP6002T-I/SN, the TSV6392AIST uniquely combines A-grade precision, integrated shutdown, and industry-leading EMI rejection - making it the only option among the three qualified for FDA-cleared diagnostic devices operating in RF-dense environments.

FAQ
What is the minimum supply voltage for reliable operation of TSV6392AIST?
The TSV6392AIST is fully specified and guaranteed to operate down to 1.5 V, with all key parameters (gain bandwidth, offset, CMRR) characterized at 1.8 V, 3.3 V, and 5 V. At 1.5 V, the device maintains rail-to-rail input/output functionality and 2 MHz GBP, enabling compatibility with single alkaline or NiMH cells without voltage boosting.
Does TSV6392AIST require external compensation for stability?
No external compensation is required. The TSV6392AIST is internally compensated for stable operation at closed-loop gains ≥4 (non-inverting) or ≥–3 (inverting) with 100 pF capacitive load. For gains below these thresholds, ST recommends using the unity-gain-stable TSV63x family instead to prevent oscillation.
How does the SHDN pin behave during power-up?
The SHDN pin has no internal pull-up or pull-down; it must be actively driven to VCC+ (≥2 V at 5 V supply) to enable operation or to VCC– (≤0.8 V) to enter shutdown. Leaving SHDN floating may cause undefined behavior or partial activation; ST recommends tying it to VCC+ via a 100 kΩ resistor if always-enabled operation is intended.
Can TSV6392AIST drive a 100 pF capacitive load directly?
Yes - the TSV6392AIST is characterized for stability with 100 pF load in closed-loop configurations meeting minimum gain requirements (≥4 non-inverting, ≥–3 inverting). However, for optimal settling time and minimal overshoot, ST recommends adding a 2–10 Ω series resistor between output and capacitive load to isolate the amplifier from pure capacitance.
