Product details
Overview
TSV6390AILT from STMicroelectronics is a micropower, rail-to-rail input/output CMOS operational amplifier with 500 µV max offset voltage (A-grade), 60 µA typical supply current at 5 V, 2.4 MHz gain bandwidth product, shutdown capability, and operation from 1.5 V to 5.5 V. It serves as a precision signal-conditioning amplifier in low-voltage, battery-powered sensor interfaces and portable medical instrumentation.
For engineers reviewing the TSV6390AILT datasheet, TSV6390AILT pinout, TSV6390AILT application, or TSV6390AILT equivalent, key selection considerations include its guaranteed 500 µV max Vio at -40 °C to 125 °C, 5 nA typical shutdown current, 63 mA output drive at 5 V, SC70-6 package footprint, and stability at gains ≥4 or ≤-3.
Technical Context
The TSV6390AILT employs complementary PMOS/NMOS input pairs enabling true rail-to-rail input common-mode range (VCC- − 0.1 V to VCC+ + 0.1 V) and rail-to-rail output swing within 35 mV of rails under 10 kΩ load. Its internal compensation ensures phase-margin-stable operation only at closed-loop gains ≥4 (non-inverting) or ≤-3 (inverting), with 60° phase margin verified at 20 pF load.
It integrates a dedicated SHDN pin that places the amplifier in high-impedance output state with 5 nA typical ICC in shutdown, 300 ns turn-on time, and logic-compatible thresholds (VIL = 0.5 V, VIH = 4.5 V at VCC = 5 V). Input bias current remains ultra-low at 1 pA typical across temperature due to CMOS input stage design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct use with single-cell Li-ion, NiMH, or 3.3 V/5 V logic rails without level shifting. |
| Offset Voltage (max) | 500 µV - A-grade specification ensures <0.1% error in 0.5 V full-scale sensor signal amplification at room temperature. |
| Supply Current (typ) | 60 µA at 5 V - supports >1-year battery life in coin-cell–powered devices operating at 100 µA average system current. |
| Gain Bandwidth Product | 2.4 MHz - delivers 10 kHz bandwidth at gain = 240, sufficient for ECG front-end filtering and active anti-aliasing. |
| Shutdown Current (typ) | 5 nA - reduces quiescent power to <30 nW, critical for wake-on-event architectures in wearable health monitors. |
| Output Drive | 63 mA sink/source at 5 V - directly drives 80 Ω loads (e.g., 50 Ω coax + 30 Ω termination) without external buffers. |
| Input Bias Current | 1 pA typical - prevents significant voltage drop across >100 MΩ source impedances (e.g., pH electrodes, piezoelectric sensors). |
Pinout & Package
TSV6390AILT is packaged in SC70-6 (SOT323-6), a 1.8 mm × 2.2 mm × 0.9 mm surface-mount package with 0.65 mm lead pitch and exposed pad option (not thermally enhanced per datasheet). Pin 1 is marked by a dot; device orientation follows JEDEC MO-203AA standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | CMOS input node with 1 pA bias current; accepts signals from VCC- − 0.1 V to VCC+ + 0.1 V. |
| 2 (IN−) | Inverting input | Differential pair input; matched to Pin 1 for <500 µV offset in A-grade units. |
| 3 (VCC−) | Negative supply | Ground reference for single-supply operation; must be tied to system GND when using 1.5–5.5 V single rail. |
| 4 (SHDN) | Shutdown control | Active-low logic input; pulls to VCC− to disable amplifier and reduce ICC to 5 nA. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable; swings within 35 mV of VCC−/VCC+ into 10 kΩ load; high-Z in shutdown. |
| 6 (VCC+) | Positive supply | Accepts 1.5–5.5 V; requires 10 nF ceramic decoupling capacitor placed adjacent to this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed A-grade offset | 500 µV max over -40 °C to 125 °C - eliminates need for external trimming in industrial temperature-critical sensor nodes. |
| Stable at gain ≥4 | 60° phase margin confirmed at gain = 4 with 20 pF capacitive load - enables robust active filter designs without external compensation. |
| Ultra-low shutdown current | 5 nA typical at 25 °C - allows microcontroller to fully power-gate analog front-end while retaining sub-µA system sleep current. |
| Rail-to-rail I/O | Input extends 0.1 V beyond rails; output reaches within 35 mV - maximizes dynamic range in 1.8 V or 3.3 V ADC systems. |
| ESD robustness | 4 kV HBM rating - withstands handling and board-level ESD events without protection diodes or layout overhead. |
Applications
| Portable ECG Monitor | Smart Smoke Detector Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6390ILT | Same die, SOT23-6 package; 4.5 V VIH, 60 µA ICC, no A-grade offset guarantee (3 mV max) | Lacks guaranteed 500 µV offset; suitable where cost sensitivity outweighs precision requirement | Select when production volume justifies trade-off of ±2.5× higher offset for 15% lower unit cost and larger SOT23-6 handling margin |
| MCP6001T-E/OT | 6 µA ICC, 1 MHz GBP, 1.6 V min supply, no shutdown, 1.5 mV Vio max | Lower power but slower; lacks shutdown and rail-to-rail input; not qualified to 125 °C | Choose only for ultra-low-power (<10 µA) applications below 85 °C ambient where 500 µV offset is non-critical |
Compared with TSV6390AILT, TSV6390ILT sacrifices guaranteed low offset for broader package availability and lower cost, while MCP6001T-E/OT offers deeper micropower but fails to meet industrial temperature, precision, and feature requirements of demanding sensor interfaces.

FAQ
What is the maximum capacitive load the TSV6390AILT can drive while maintaining stability?
The TSV6390AILT is stable with up to 20 pF capacitive load when configured at minimum gain (≥4 non-inverting or ≤-3 inverting), as verified by 60° phase margin testing. Driving >20 pF requires external isolation resistor (e.g., 10–100 Ω in series with output) to prevent peaking or oscillation, especially in active filter or ADC driver configurations.
Does the TSV6390AILT require external compensation for unity-gain operation?
No - the TSV6390AILT is explicitly not unity-gain stable. Attempting unity-gain configuration causes instability and oscillation. For unity-gain applications, ST recommends the TSV630-1 (880 kHz GBP, unity-gain stable) or TSV6290-1 (1.3 MHz GBP, unity-gain stable), both sharing the same SC70-6/SOT23-6 footprint compatibility.
How does the shutdown function affect output state and leakage?
When SHDN is pulled low (≤0.5 V), the amplifier output enters high-impedance state with ≤1 nA leakage current (typical 50 pA) and ICC drops to 5 nA. The output remains floating - no internal clamping or pull-down - so external biasing or hold circuitry is required if defined voltage is needed during shutdown.
Can the TSV6390AILT operate reliably from a 1.5 V supply?
Yes - the TSV6390AILT is fully characterized and guaranteed from 1.5 V to 5.5 V. At 1.5 V, it delivers 2 MHz GBP, 60 µA ICC, and rail-to-rail I/O swing, making it suitable for single-cell alkaline or NiMH battery systems where headroom is constrained and precision must be maintained.
