Product details
Overview
TSV620AILT from STMicroelectronics is a rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, precision signal conditioning in battery-powered systems. It delivers 420 kHz gain bandwidth at 29 µA supply current (5 V), 800 µV max input offset voltage (A-grade), and operates from 1.5 V to 5.5 V across –40 °C to +125 °C. Its integrated shutdown function reduces quiescent current to 5 nA, enabling long-life portable medical sensors and wearable instrumentation.
For engineers reviewing the TSV620AILT datasheet, TSV620AILT pinout, TSV620AILT application, or TSV620AILT equivalent, key selection criteria include its guaranteed 800 µV max VIO (A-version), 420 kHz GBP at 29 µA, SC70-6/SOT23-6 package compatibility, and verified shutdown behavior with 300 ns turn-on time - all critical for low-voltage sensor front-ends and energy-constrained IoT nodes.
Technical Context
The TSV620AILT employs complementary PMOS/NMOS input stages to achieve 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 into 10 kΩ). Its internal trimming ensures tight dispersion of DC/AC parameters: supply current ±17%, GBP ≥350 kHz min, and slew rate ≥0.15 V/µs min.
It features a dedicated SHDN pin (logic high enables, logic low disables) that places the output in high-impedance state while reducing ICC to 5 nA typ at 5 V. The device is unity-gain stable driving capacitive loads ≤100 pF and supports operation down to 1.5 V with full parameter specification at 1.8 V, 3.3 V, and 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct integration with single-cell Li-ion, alkaline, or coin-cell batteries without regulation. |
| Input Offset Voltage (max) | 800 µV - A-grade precision ensures <±0.5 mV error in 12-bit ADC front-ends at room temperature. |
| Quiescent Current (typ) | 29 µA at 5 V - extends battery life in always-on sensor nodes beyond 10 years on a CR2032 cell. |
| Gain Bandwidth Product | 420 kHz - supports anti-aliasing filtering up to ~65 kHz with unity-gain stability and 100 pF load tolerance. |
| Shutdown Current (typ) | 5 nA at 5 V - reduces system standby power by >5,000× versus active mode, critical for duty-cycled sensing. |
| Rail-to-Rail I/O | Input: (VCC– –0.1 V) to (VCC+ +0.1 V); Output: within 35 mV of rails - maximizes dynamic range in low-voltage systems. |
| ESD Robustness | 4 kV HBM - withstands handling and board-level ESD events without protection diodes or layout overhead. |
Pinout & Package
TSV620AILT is available in SC70-6 and SOT23-6 packages. Both are 6-pin micropackages with identical pin mapping: Pin 1 = SHDN, Pin 2 = In–, Pin 3 = In+, Pin 4 = VCC–, Pin 5 = Out, Pin 6 = VCC+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low enable: pulled high (≥4.5 V at 5 V supply) for normal operation; pulled low (≤0.5 V) for 5 nA standby mode. |
| 2 (In–) | Inverting input | Differential node for feedback networks; accepts common-mode voltages from VCC– –0.1 V to VCC+ +0.1 V. |
| 3 (In+) | Non-inverting input | Reference or sensor input node; same rail-to-rail common-mode range as In–. |
| 4 (VCC–) | Negative supply rail | Ground reference for single-supply operation; must be decoupled with 10 nF capacitor near pin. |
| 5 (Out) | Amplifier output | Delivers rail-to-rail swing (within 35 mV of VCC–/VCC+) into ≥10 kΩ loads; high-Z in shutdown. |
| 6 (VCC+) | Positive supply rail | Primary power input (1.5–5.5 V); requires local 10 nF decoupling to maintain stability and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Low-Voltage Operation | Functional down to 1.5 V with full AC/DC specs guaranteed - eliminates need for LDO in single-cell designs. |
| Guaranteed A-Grade Precision | 800 µV max input offset voltage over full temperature range - enables accurate DC-coupled sensor amplification without calibration. |
| Tight Parameter Dispersion | ±17% supply current variation - ensures consistent GBP (≥350 kHz) and slew rate (≥0.15 V/µs) across production lots. |
| Integrated Shutdown | 300 ns turn-on time and 30 ns turn-off time - supports microsecond-scale wake/sleep cycles in energy-harvesting systems. |
| Capacitive Load Drive | Stable with ≤100 pF capacitive loads in unity-gain configuration - simplifies filter design without external compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV620ILT | No A-grade offset spec (6 mV max vs. 0.8 mV max); same pinout, shutdown, and power specs. | Suitable for non-precision signal paths where cost sensitivity outweighs DC accuracy requirements. | Select when VIO >1 mV is acceptable and budget constraints dominate. |
| MCP6001UT-E/OT | Higher 100 µA ICC; no shutdown; 1 MHz GBP; 2 mV max VIO; SOT23-5 package only. | Lacks shutdown and A-grade precision; limited to 5.5 V supply but offers higher speed for AC-coupled apps. | Choose only if higher bandwidth is required and shutdown/low ICC are not needed. |
Compared with TSV620AILT, TSV620ILT trades precision for lower unit cost in non-critical paths, while MCP6001UT-E/OT provides higher bandwidth at 3.4× the quiescent current and no power-gating capability - making TSV620AILT uniquely suited for precision, ultra-low-power, shutdown-enabled sensor interfaces.

FAQ
What is the maximum capacitive load the TSV620AILT can drive stably in unity-gain configuration?
The TSV620AILT is unity-gain stable driving capacitive loads up to 100 pF without external compensation. This is verified per datasheet Section 3.6 and Figure 20. For loads exceeding 100 pF, a small series resistor (e.g., 10–100 Ω) at the output is recommended to restore phase margin, and bench validation is required per application conditions.
Does the TSV620AILT require external components for shutdown functionality?
No external components are required for basic shutdown operation. The SHDN pin is CMOS-compatible: pull it high (≥4.5 V at 5 V supply) to enable, or low (≤0.5 V) to disable. However, the pin must never float - tie directly to VCC+ or VCC– via a clean digital signal or pull-up/down resistor per PCB layout guidelines in Section 3.4.
How does the TSV620AILT's input offset voltage drift compare across temperature?
The TSV620AILT exhibits a guaranteed input offset voltage drift of 2 µV/°C maximum over –40 °C to +125 °C. At 25 °C, VIO is ≤800 µV (A-grade); worst-case drift adds ≤350 µV over the full range, keeping total VIO ≤1.15 mV - sufficient for 12-bit accuracy in DC-coupled sensor amplifiers.
Can the TSV620AILT operate from a 1.5 V supply while maintaining specified gain bandwidth?
Yes - the TSV620AILT is fully characterized and specified down to 1.5 V supply. At 1.5 V, the typical gain bandwidth product is 275 kHz (min 200 kHz), with corresponding slew rate of 0.084 V/µs. All DC parameters including VIO, IIB, and CMRR remain guaranteed per Table 3, enabling true single-cell alkaline or LiFePO₄ compatibility.
