Product details
Overview
TSV630ILT from STMicroelectronics is a rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, precision battery-powered systems. It delivers 880 kHz gain bandwidth at 60 µA quiescent current (5 V), supports 1.5 V to 5.5 V supply, features 500 µV max offset voltage (A-grade), and includes active shutdown mode drawing only 5 nA typ. It is used in medical sensor front-ends requiring rail-to-rail swing and low drift over -40 °C to 125 °C.
For engineers reviewing the TSV630ILT datasheet, TSV630ILT pinout, TSV630ILT application, or TSV630ILT equivalent, key selection criteria include its 1 pA input bias current, 63 mA output drive capability at 5 V, shutdown logic compatibility (VIH = 4.5 V, VIL = 0.5 V), and unity-gain stability with ≤100 pF capacitive loads - critical for portable instrumentation and low-voltage active filtering.
Technical Context
The TSV630ILT employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range from (VCC–) – 0.1 V to (VCC+) + 0.1 V, with no phase reversal. Its internal trimming ensures tight dispersion of GBP (min 730 kHz) and slew rate (min 0.25 V/µs), directly linked to its 60 µA supply current.
Shutdown is controlled by a dedicated SHDN pin: pulled high (≥4.5 V at 5 V VCC) enables operation; pulled low (≤0.5 V) disables the amplifier and places output in high-impedance state, reducing ICC to 5 nA typ. Turn-on/off times are specified at 300 ns / 30 ns respectively under 2 kΩ load.
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 (3.0–4.2 V), alkaline (1.5 V), or regulated 3.3 V/5 V rails without level-shifting. |
| Quiescent Current | 60 µA typ at 5 V - extends battery life in always-on sensor nodes; drops to 5 nA in shutdown mode. |
| Gain Bandwidth Product | 880 kHz typ - supports stable unity-gain buffering of DC–~100 kHz signals (e.g., ECG, temperature transducers) with minimal power penalty. |
| Input Offset Voltage | 500 µV max (A version) - ensures <0.1% error in 0.5 V full-scale medical analog front-ends without trimming. |
| Input Bias Current | 1 pA typ - eliminates significant voltage error across high-impedance pH or photodiode sources (>100 MΩ). |
| Rail-to-Rail I/O | Input CMR: (VCC–) – 0.1 V to (VCC+) + 0.1 V; Output swing: within 35 mV of rails (10 kΩ load) - maximizes dynamic range in low-voltage ADC interfacing. |
| Output Drive | ±63 mA at VCC = 5 V - drives 8 Ω headphones or 100 Ω DAC buffers without external gain stage. |
Pinout & Package
TSV630ILT is packaged in SOT23-6 (6-pin small outline transistor) - a surface-mount, lead-free, RoHS-compliant package measuring 2.9 mm × 1.6 mm × 1.1 mm, optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low enable: tie to VCC+ for operation; pull to VCC– for 5 nA standby. Must not float - prevents undefined output state. |
| 2 (IN–) | Inverting input | Differential node for feedback networks; 1 pA bias current minimizes error in high-Z configurations (e.g., transimpedance amps). |
| 3 (IN+) | Non-inverting input | Reference or signal input; rail-to-rail CMR allows direct connection to 0–5 V sensor outputs without clamping diodes. |
| 4 (VCC–) | Negative supply | Ground reference (0 V) in single-supply designs; decoupling capacitor (10 nF) required adjacent to pin for stability. |
| 5 (OUT) | Amplifier output | Capable of sourcing/sinking ±63 mA; rail-to-rail swing enables full utilization of 12-bit ADC input range (0–VCC). |
| 6 (VCC+) | Positive supply | Accepts 1.5–5.5 V; internal regulation ensures consistent GBP and offset across voltage range - critical for battery discharge tracking. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power shutdown | 5 nA ICC in shutdown - reduces system leakage by >4 orders of magnitude vs. active mode, enabling multi-year coin-cell operation. |
| High output current | 63 mA sink/source at 5 V - eliminates need for external buffer in driving LED indicators, relays, or low-impedance filters. |
| Ultra-low input bias | 1 pA typical - preserves signal integrity in piezoelectric, ion-selective, or MEMS sensor interfaces where source impedance exceeds 1 GΩ. |
| Tight parameter dispersion | ±17% variation in ICC across production lot - ensures predictable GBP (730–880 kHz) and SR (0.25–0.34 V/µs) without per-unit calibration. |
| Extended temperature range | -40 °C to +125 °C - qualified for under-hood automotive sensors and industrial motor controllers without derating. |
Applications
| Medical Sensor Interface | Battery-Powered Data Logger |

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 |
|---|---|---|---|
| TSV631ILT | No shutdown pin; 5-pin SOT23 package; identical AC/DC specs except missing SHDN functionality. | Suitable where continuous operation is required and board space is constrained (5-pin vs. 6-pin). | Select when shutdown is unnecessary and footprint reduction is prioritized over control flexibility. |
| MCP6001T-I/OT | Higher 100 µA ICC; lower 1 MHz GBP; no guaranteed 125 °C operation; 4.5 V min VIH limits 3.3 V logic compatibility. | Cost-optimized for consumer wearables where extended temp range and ultra-low shutdown current are non-critical. | Choose for price-sensitive, room-temperature applications where 5 nA shutdown and AEC-Q100 are not required. |
Compared with TSV631ILT, TSV630ILT trades pin count for system-level power control; versus MCP6001T-I/OT, it delivers superior thermal robustness, lower leakage, and tighter parameter consistency - essential for automotive and medical certifications.

FAQ
What is the minimum supply voltage for reliable operation of TSV630ILT?
The TSV630ILT operates reliably down to 1.5 V, with full electrical specifications guaranteed at 1.8 V, 3.3 V, and 5 V. At 1.5 V, gain bandwidth drops to ~730 kHz and output drive reduces proportionally, but rail-to-rail input/output and shutdown functionality remain fully functional across the -40 °C to +125 °C range.
Can TSV630ILT drive a 100 pF capacitive load without oscillation?
Yes - the TSV630ILT is unity-gain stable with capacitive loads up to 100 pF when configured as a voltage follower. For loads exceeding 100 pF, ST recommends adding a series resistor (Riso) at the output; Figure 23 in the datasheet provides validated Riso values (e.g., 10 Ω for 330 pF) to maintain ≥48° phase margin.
How does the shutdown pin behave with 3.3 V logic levels?
At VCC = 3.3 V, the SHDN pin requires ≥2.2 V (VIH) to enable and ≤0.5 V (VIL) to disable. A standard 3.3 V GPIO can directly control it: logic HIGH (3.3 V) enables the amplifier; logic LOW (0 V) places output in high-Z and reduces ICC to 50 nA typ (–40 °C to +85 °C) or 1.5 µA max (–40 °C to +125 °C).
Is TSV630ILT pin-compatible with other ST micropower op-amps like TSV611 or TSV621?
No - TSV630ILT uses SOT23-6 packaging with dedicated SHDN pin, while TSV611 (SOT23-5) and TSV621 (SOT23-6) have different pinouts: TSV611 lacks shutdown and has no IN– pin in 5-pin format; TSV621's SHDN is on pin 5 (not pin 1), and its output is on pin 1. Direct replacement requires PCB redesign.
