Product details
Overview
TSV620ILT from STMicroelectronics is a rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, single-supply operation across 1.5 V–5.5 V. It delivers 420 kHz gain bandwidth at 29 µA supply current, features 800 µV max input offset voltage (A version), 1 pA typical input bias current, and integrated shutdown functionality with 5 nA typ current draw. It is used in precision sensor signal conditioning within battery-powered medical instrumentation.
For engineers reviewing the TSV620ILT datasheet, TSV620ILT pinout, TSV620ILT application, or TSV620ILT equivalent, key selection criteria include its shutdown-enabled low-power profile (29 µA active / 5 nA shutdown), rail-to-rail I/O swing at sub-2 V supply, guaranteed -40 °C to +125 °C operation, and SC70-6/SOT23-6 package compatibility for space-constrained portable designs.
Technical Context
The TSV620ILT implements dual complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V) and output swing within 35 mV of both rails under 10 kΩ load. Its internal trimming ensures tight dispersion of DC/AC parameters-supply current ±17%, GBP ≥350 kHz min, slew rate ≥0.15 V/µs min-enabling consistent performance across temperature and voltage.
Shutdown control is implemented via a dedicated SHDN pin requiring logic-high enable (VIH = 4.5 V @ VCC = 5 V) and logic-low disable (VIL = 0.5 V); output enters high-impedance state with 1 nA leakage max at 125 °C. The device is unity-gain stable driving capacitive loads ≤100 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5 V–5.5 V: Enables direct integration into single-cell Li-ion (3.0–4.2 V), coin-cell (1.5–3.0 V), and 5 V legacy systems without LDO pre-regulation. |
| Quiescent Current | 29 µA typ @ 5 V: Supports >1-year battery life in always-on wearable sensors drawing <10 µA average system current. |
| Shutdown Current | 5 nA typ @ 5 V: Reduces standby power by 5,800× versus active mode-critical for intermittent-sampling architectures. |
| Gain Bandwidth Product | 420 kHz typ @ 5 V: Sufficient for anti-aliasing filters up to ~66 kHz and sensor amplification with <1% gain error at 10 kHz. |
| Input Offset Voltage | 0.8 mV max (TSV620A variant): Limits DC error to <0.016% FS in 5 V full-scale bridge sensor interfaces. |
| Input Bias Current | 1 pA typ: Prevents significant voltage drop across >100 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors). |
| ESD Rating | 4 kV HBM: Meets IEC 61000-4-2 Level 2 for handheld medical devices exposed to routine handling discharge events. |
Pinout & Package
TSV620ILT is packaged in SOT23-6 (6-pin) and SC70-6 (6-pin) micropackages. Both are RoHS-compliant, surface-mount, lead-free packages with identical pin mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC+) | Positive Supply Rail | Accepts 1.5–5.5 V; decoupling capacitor (10 nF) required adjacent to pin for stability. |
| 2 (IN−) | Inverting Input | Differential pair node; rail-to-rail common-mode range supports direct connection to grounded sensors. |
| 3 (IN+) | Non-inverting Input | Differential pair node; 1 pA bias current enables high-Z source interfacing without loading error. |
| 4 (OUT) | Amplifier Output | Rail-to-rail swing (≤35 mV from rails @ 10 kΩ); drives capacitive loads ≤100 pF directly. |
| 5 (SHDN) | Shutdown Control | Active-high logic input; pulls to VCC+ to enable, VCC− to disable; must not float. |
| 6 (VCC−) | Negative Supply Rail / Ground | Reference node for single-supply operation; ties to system ground in most battery applications. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-E/OT (Microchip) | No shutdown pin; 1 µA higher quiescent current (30 µA vs. 29 µA); 100 kHz GBP vs. 420 kHz. | Lacks power-gating capability; lower bandwidth limits use in >15 kHz sensor filtering. | Select when shutdown is unnecessary and cost sensitivity outweighs bandwidth needs. |
| TLV9001IDBVR (TI) | Higher supply current (65 µA); includes EMI-hardened input; 1 MHz GBP; no guaranteed 125 °C operation. | Better noise immunity in noisy environments but consumes >2× current; rated only to 125 °C with derating. | Select for EMI-prone industrial settings where power budget allows extra 36 µA. |
Compared with MCP6001T-E/OT and TLV9001IDBVR, TSV620ILT uniquely balances ultra-low shutdown current (5 nA), 420 kHz bandwidth, and full -40 °C to +125 °C guarantee-making it optimal for long-life, temperature-resilient, intermittently active sensing nodes.

FAQ
What is the maximum capacitive load the TSV620ILT can drive without oscillation?
The TSV620ILT is unity-gain stable and can drive capacitive loads up to 100 pF directly without external compensation. Driving larger loads requires adding a small series resistor (e.g., 10–100 Ω) between the output and load capacitance, with final stability verified through bench testing and SPICE simulation using ST's official macromodel.
Does the TSV620ILT require external passive components for basic operation?
No external passive components are required for basic operation: a 10 nF ceramic decoupling capacitor placed close to the VCC+ and VCC− pins is the only mandatory external component. No input biasing resistors, compensation networks, or level-shifters are needed due to rail-to-rail input/output and internal trimming.
How does the shutdown function affect output state and leakage?
When SHDN is pulled low (to VCC−), the amplifier output enters a high-impedance state with ≤1 nA leakage current at 125 °C. The output remains floating-not clamped or shorted-so external pull-up/down resistors may be needed depending on downstream circuit requirements to avoid undefined logic states.
Is the TSV620ILT pin-compatible with other members of the TSV62x family?
Yes-TSV620ILT (SOT23-6/SC70-6) shares identical pinout with TSV620ICT, TSV620AILT, and TSV620AICT. However, TSV621 variants (SOT23-5/SC70-5) have different pin counts and mappings; they lack the SHDN pin and are not mechanically or electrically interchangeable.
