Product details
Overview
TSV630AILT 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 880 kHz gain bandwidth at 60 µA quiescent current (5 V), supports 1.5–5.5 V supply, features 500 µV max offset voltage (A-grade), and includes active shutdown mode drawing only 5 nA typical. It is used in medical sensor front-ends requiring rail-to-rail swing and stable DC accuracy over –40 °C to 125 °C.
For engineers reviewing the TSV630AILT datasheet, TSV630AILT pinout, TSV630AILT application, or TSV630AILT 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 ECG and glucose monitor analog signal chains.
Technical Context
The TSV630AILT employs 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 trimming ensures tight dispersion of GBP (730–880 kHz min–typ) and slew rate (0.25–0.34 V/µs), directly tied to its 60 µA supply current.
Shutdown control is implemented via a dedicated SHDN pin that places the output in high-impedance state when pulled to VCC−; turn-on/off times are specified at 300 ns / 30 ns (5 V, RL = 2 kΩ). The device maintains ≥55 dB CMRR and ≥75 dB SVR across full temperature and supply range.
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 (3.0–4.2 V) or two alkaline cells (up to 3.2 V). |
| Quiescent Current | 60 µA typ at 5 V - extends battery life in always-on wearable sensors beyond 1 year on CR2032. |
| Gain Bandwidth Product | 880 kHz typ - supports anti-aliasing filtering up to ~140 kHz while preserving low-noise integrity. |
| Input Offset Voltage | 500 µV max (A-grade) - ensures ≤0.01% gain error in 10-bit ADC interfaces without calibration. |
| Output Drive Current | ±63 mA at VCC = 5 V - drives 80 Ω loads directly, eliminating need for external buffer in transducer drivers. |
| Shutdown Current | 5 nA typ - reduces system standby power to sub-nW level, critical for energy-harvesting nodes. |
| Input Bias Current | 1 pA typ - prevents leakage-induced drift in high-impedance pH or ion-selective electrode circuits. |
Pinout & Package
TSV630AILT is supplied in SOT23-6 package (6-pin, 2.9 mm × 1.6 mm × 1.1 mm), RoHS-compliant and ECOPACK® certified. Pin 1 is marked by a dot; device orientation follows JEDEC MO-178AB standard.
| 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 shutdown. Must not float. |
| 2 (IN−) | Inverting input | Differential node for feedback networks; rail-to-rail capable with ±0.1 V beyond rails. |
| 3 (IN+) | Non-inverting input | High-impedance sensor interface node; 1 pA bias current minimizes loading on piezoresistive bridges. |
| 4 (V−) | Negative supply | Ground reference for single-supply operation; supports true 0 V input/output swing. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable: within 35 mV of rails into 10 kΩ load; stable driving ≤100 pF capacitance. |
| 6 (V+) | Positive supply | Accepts 1.5–5.5 V; decoupling with 10 nF capacitor required adjacent to pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O with no phase reversal | Enables full dynamic range utilization in 0–5 V microcontroller ADC systems without level-shifting. |
| Automotive-qualified (-40 °C to 125 °C) | Validated for under-hood telematics and ADAS sensor modules where thermal cycling exceeds industrial grade. |
| Unity-gain stable with ≤100 pF load | Eliminates need for external compensation in photodiode transimpedance amplifiers or capacitive touch filters. |
| Low THD+N (0.0017 % at 1 kHz) | Preserves signal fidelity in audio preamps and biopotential amplifiers where harmonic distortion masks low-amplitude events. |
| Guaranteed minimum GBP & SR | Ensures consistent settling behavior across production lots - critical for time-critical pulse detection in pulse oximetry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV621ILT | Lower power (29 µA), lower GBP (420 kHz), no shutdown pin | Suitable for always-on ultra-low-power apps where speed <420 kHz suffices and shutdown is unnecessary | Select when battery life >5 years is mandatory and signal bandwidth ≤70 kHz |
| MCP6001T-I/OT | Higher offset (1.5 mV max), no A-grade option, 100 nA shutdown current | General-purpose replacement where automotive temp range and sub-500 µV offset are not required | Select for cost-sensitive consumer devices with 0–70 °C operation and relaxed DC accuracy |
Compared with TSV630AILT, TSV621ILT trades 47% lower supply current for 52% reduced bandwidth and loss of shutdown control, while MCP6001T-I/OT offers broader availability but lacks A-grade precision and automotive qualification - making TSV630AILT optimal for safety-critical, battery-constrained medical and industrial edge nodes.

FAQ
What is the maximum capacitive load the TSV630AILT can drive without oscillation?
The TSV630AILT is unity-gain stable driving up to 100 pF capacitive load in follower configuration. For larger loads, an in-series resistor (e.g., 10–100 Ω) must be added at the output per Figure 23 in the datasheet; stability must then be verified experimentally and in simulation using ST's macromodel.
Does the TSV630AILT require external compensation for gain-of-10 configurations?
No external compensation is needed for gains ≥10. The device is internally compensated for unity-gain stability, and phase margin remains ≥50° across all closed-loop gains per Table 6 (5 V, RL = 2 kΩ, CL = 100 pF), ensuring robust performance in standard non-inverting and inverting amplifier topologies.
Can the SHDN pin be driven directly by a 3.3 V GPIO from an ARM Cortex-M0+ MCU?
Yes - the SHDN pin VIH threshold is 4.5 V minimum at VCC = 5 V, but at VCC = 3.3 V, VIH is guaranteed ≥2.3 V per characterization data. A 3.3 V GPIO meets this requirement with margin; however, ensure the MCU GPIO can sink the 10 pA SHDN input current when pulled low.
Is the TSV630AILT pin-compatible with other members of the TSV63x family?
Yes - TSV630AILT (SOT23-6) shares identical pinout with TSV630, TSV630A, TSV631, and TSV631A in the same package variant. However, TSV631 variants lack the SHDN pin (5-pin SOT23-5), so PCB layout must match the specific part's pin count and function mapping.
