Product details
Overview
TSV6390ICT from STMicroelectronics is a micropower, rail-to-rail input/output CMOS operational amplifier with 2.4 MHz gain bandwidth product, 60 µA supply current at 5 V, and integrated shutdown function. It operates from 1.5 V to 5.5 V, delivers ±63 mA output drive, and supports precision signal conditioning in battery-powered sensor interfaces.
For engineers reviewing the TSV6390ICT datasheet, TSV6390ICT pinout, TSV6390ICT application, or TSV6390ICT equivalent, this device is selected for low-voltage, low-power analog front-ends requiring stable DC accuracy (500 µV max offset for A-version), fast settling (300 ns turn-on), and ESD-hardened operation (4 kV HBM) in compact SC70-6 packaging.
Technical Context
The TSV6390ICT uses complementary PMOS/NMOS input stages enabling true 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 ≥ −3 or ≥ 4 with 60° phase margin.
Shutdown control is implemented via a dedicated SHDN pin (VIH = 4.5 V, VIL = 0.5 V at VCC = 5 V), reducing supply current to 5 nA typical while placing output in high-impedance state. Turn-off time is 30 ns, turn-on time 300 ns under RL = 2 kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct operation from single-cell Li-ion, alkaline, or coin-cell batteries. |
| Quiescent Current | 60 µA typical at 5 V - extends battery life in always-on portable instrumentation. |
| Gain Bandwidth Product | 2.4 MHz typical - supports active filtering up to ~200 kHz with gain ≥ 4. |
| Input Offset Voltage | 500 µV max (A version) - ensures ≤ 0.5 mV error in 1 V full-scale sensor amplification. |
| Rail-to-Rail I/O | Input: VCC− −0.1 V to VCC+ +0.1 V; Output: within 35 mV of rails at 10 kΩ - maximizes dynamic range in low-voltage systems. |
| ESD Rating | 4 kV HBM - eliminates need for external protection in handheld medical or industrial sensors. |
| Shutdown Current | 5 nA typical at 5 V - reduces standby power by >10⁴× vs active mode. |
Pinout & Package
TSV6390ICT is housed in a 6-pin SC70-6 (SOT323-6) package measuring 2.2 × 1.35 × 1.1 mm (max), optimized for space-constrained PCB layouts in wearable and IoT edge nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | Accepts signals from 0.1 V below VCC− to 0.1 V above VCC+; bias current ≤1 pA minimizes leakage errors in high-Z sensor bridges. |
| 2 (IN−) | Inverting input | Differential node for feedback networks; input offset drift ≤2 µV/°C ensures thermal stability across −40 °C to 125 °C. |
| 3 (V−) | Negative supply rail | Ground reference for single-supply operation; supports 0 V connection in unipolar systems. |
| 4 (SHDN) | Shutdown enable control | Active-low logic input; pulls to V− to disable amplifier and reduce ICC to 5 nA; must not float. |
| 5 (OUT) | Amplifier output | Drives loads up to 63 mA sink/source; maintains rail-to-rail swing with <35 mV headroom at 10 kΩ. |
| 6 (V+) | Positive supply rail | Accepts 1.5–5.5 V; internal regulation ensures consistent GBP and SR across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown mode | 5 nA ICC in shutdown - enables microamp-level system sleep states without external power gating. |
| Precision DC performance | 500 µV max Vio (A version) and 2 µV/°C drift - eliminates calibration in medical ECG front-ends operating over industrial temperature range. |
| Rail-to-rail output swing | Within 35 mV of V+ and V− at 10 kΩ - preserves >98% of 1.8 V supply headroom for ADC interfacing. |
| High output drive capability | ±63 mA at VCC = 5 V - directly drives LED indicators, small solenoids, or 50 Ω transmission lines without buffer stages. |
| Stable at low noise gain | Minimum stable gain = −3 or 4 - supports transimpedance configurations for photodiode amplification with minimal external compensation. |
Applications
| Portable Medical Sensors | Battery-Powered Data Loggers |

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 | SOT23-6 package (3.05 × 1.75 mm); 0.5 mm larger footprint; identical electrical specs. | Better thermal dissipation (Rthja = 240 °C/W vs 232 °C/W) for continuous 63 mA output in high-ambient environments. | Select when board layout allows larger pad area and thermal relief is critical for sustained output current. |
| TSV6290ICT | Lower GBP (1.3 MHz), lower ICC (29 µA), unity-gain stable - no minimum gain requirement. | Preferred for gain = 1 configurations (e.g., voltage followers driving capacitive loads) where TSV6390ICT requires ≥ −3 gain. | Choose when simplicity of unity-gain stability outweighs need for 2.4 MHz bandwidth and higher output drive. |
Compared with TSV6390ILT, TSV6390ICT saves 0.3 mm² board area but trades 8 °C/W higher thermal resistance; versus TSV6290ICT, it delivers 85% more bandwidth and 117% higher output current at cost of stricter gain stability constraints.

FAQ
What is the maximum capacitive load the TSV6390ICT can drive without instability?
The TSV6390ICT is not unity-gain stable and requires minimum closed-loop gain of −3 (inverting) or 4 (non-inverting) for stability with 100 pF capacitive load. Driving >100 pF directly risks peaking or oscillation; for larger loads, add a series resistor (≥200 Ω) between output and capacitance, or use a unity-gain-stable alternative like TSV6290ICT.
Does the TSV6390ICT support true rail-to-rail input at 1.5 V supply?
Yes - input common-mode range extends from (V−) −0.1 V to (V+) +0.1 V across the full 1.5–5.5 V supply range. At 1.5 V, this means inputs operate from −0.1 V to +1.6 V, enabling accurate sensing of signals near ground or supply rails in single-cell battery systems.
How does shutdown affect output state and leakage?
When SHDN is pulled low (to V−), the output enters high-impedance state with ≤1 nA leakage current (typical). The amplifier core disables completely, reducing total supply current to 5 nA. Output must not be externally driven during shutdown, as no clamping diodes are guaranteed.
Can the TSV6390ICT drive a 50 Ω load at 5 V supply?
No - its specified output current (63 mA) assumes resistive loads ≥2 kΩ. Driving 50 Ω would exceed safe operating area: at 5 V, 50 Ω draws 100 mA, causing thermal overload and potential damage. For 50 Ω loads, use a dedicated line driver or add an external buffer stage.
