Product details
Overview
TSV6390AICT from STMicroelectronics is a micropower, rail-to-rail input/output single operational amplifier optimized for precision battery-powered systems. It delivers 500 µV max offset voltage (A-grade), 2.4 MHz gain bandwidth at 60 µA supply current (5 V), and operates from 1.5 V to 5.5 V - enabling high-accuracy signal conditioning in portable medical sensors and low-voltage active filters.
For engineers reviewing the TSV6390AICT datasheet, TSV6390AICT pinout, TSV6390AICT application, or TSV6390AICT equivalent, key selection criteria include its shutdown-enabled power efficiency (5 nA typ), 63 mA output drive capability at 5 V, rail-to-rail operation across -40 °C to 125 °C, and SC70-6 package compatibility with space-constrained PCB layouts.
Technical Context
The TSV6390AICT employs 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 ≥4 or ≤−3, with 60° phase margin under 10 kΩ/20 pF load conditions.
It integrates a dedicated SHDN pin that places the amplifier in high-impedance output state with 5 nA typical supply current, achieving 300 ns turn-on and <30 ns turn-off times. The device's 2 μV/°C offset drift and 80 dB CMRR (min) support stable DC-coupled sensor front-ends over full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V – 5.5 V: Enables direct operation from single Li-ion, two alkaline, or regulated 3.3 V rails without level-shifting. |
| Offset Voltage (max) | 500 µV (A version): Ensures ≤0.5 mV error in 1 V full-scale precision instrumentation amplifiers. |
| Gain Bandwidth Product | 2.4 MHz (typ @ 5 V): Supports >100 kHz closed-loop bandwidth in unity-gain stable configurations with gain ≥4. |
| Supply Current (typ) | 60 µA @ 5 V: Delivers 2.4 MHz bandwidth while consuming less than 300 µW - critical for multi-year battery life. |
| Shutdown Current (typ) | 5 nA @ 5 V: Reduces system standby power by 12,000× versus active mode - essential for duty-cycled IoT endpoints. |
| Rail-to-Rail I/O | Input extends 0.1 V beyond rails; output swings within 35 mV of rails @ 10 kΩ: Maximizes dynamic range in low-voltage ADC driver stages. |
| Output Drive | ±63 mA @ 5 V: Drives 80 Ω loads directly - eliminates need for external buffer in audio line drivers or transducer interfaces. |
Pinout & Package
TSV6390AICT is supplied in SC70-6 (SOT323-6) package: ultra-compact 2.2 × 1.35 mm footprint with 0.65 mm pitch, optimized for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting Input | High-impedance (1 pA typ bias) node accepting rail-to-rail common-mode signals - used for sensor voltage buffering. |
| 2 (IN−) | Inverting Input | Differential input node with matched layout to IN+; enables precision difference amplification with 500 µV max offset. |
| 3 (V−) | Negative Supply | Ground reference for single-supply operation; supports 0 V connection in 1.5–5.5 V systems. |
| 4 (SHDN) | Shutdown Control | Active-low logic input: pulled to V− disables amplifier and reduces ICC to 5 nA - enables firmware-controlled power gating. |
| 5 (OUT) | Amplifier Output | Class-AB rail-to-rail output capable of ±63 mA sink/source - drives resistive loads or capacitive DAC references directly. |
| 6 (V+) | Positive Supply | Primary power input; accepts 1.5–5.5 V with 6 V absolute max - compatible with coin-cell, LiPo, and LDO outputs. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6390ILT | SOT23-6 package (vs. SC70-6); identical electrical specs; 0.3 mm taller profile; 240 °C/W Rthja vs. 232 °C/W. | Better thermal dissipation in high-ambient industrial enclosures; larger footprint limits ultra-portable use. | Select when board space permits and thermal margin >5 °C is required above 125 °C ambient. |
| TSV6391AICT | Single op amp without shutdown pin; SC70-5 package (5-pin); same A-grade offset and bandwidth; no SHDN functionality. | Lower BOM cost where always-on operation suffices; missing shutdown removes firmware power control capability. | Choose only if system-level power management is handled externally and PCB area must be minimized beyond SC70-6 constraints. |
Compared with TSV6390AICT, TSV6390ILT offers superior thermal performance in constrained airflow environments but sacrifices miniaturization, while TSV6391AICT reduces cost and size at the expense of programmable power gating - making TSV6390AICT the sole choice for battery-constrained, firmware-managed sensor nodes.

FAQ
What is the minimum supply voltage for reliable operation of TSV6390AICT?
The TSV6390AICT is fully specified down to 1.5 V supply voltage, with guaranteed rail-to-rail input/output operation, 500 µV max offset, and 2.4 MHz gain bandwidth. Below 1.5 V, parameters such as CMRR and output swing degrade progressively; operation below 1.3 V is not recommended due to increased distortion and instability risk.
Can TSV6390AICT drive capacitive loads directly?
TSV6390AICT is not unity-gain stable and exhibits peaking with capacitive loads >20 pF unless compensated. For CL >20 pF, add a series resistor (≥200 Ω) between output and load, or use a gain ≥4 configuration with feedback network isolation. Stable 100 pF driving requires Rf ≥10 kΩ and gain ≥11 per datasheet Figure 5.
How does the SHDN pin behave during power-up?
The SHDN pin must be actively driven high (≥1.3 V at 1.8 V supply; ≥4.5 V at 5 V) before or concurrent with V+ application to ensure normal startup. If left floating or pulled low during power-up, the amplifier remains disabled until SHDN is asserted - no damage occurs, but output stays high-Z until valid logic high is applied.
Is TSV6390AICT suitable for driving ADC reference inputs?
Yes - its rail-to-rail output, low 500 µV offset, and 63 mA drive make it ideal for buffering precision voltage references (e.g., REF3025) into SAR ADC reference pins. Output impedance remains <1 Ω up to 100 kHz, minimizing settling error; THD+N of 0.11% at 1 kHz ensures clean reference spectral purity.
