Product details
Overview
TSV630IQ2T from STMicroelectronics is a rail-to-rail input/output CMOS operational amplifier optimized for ultra-low-power, precision signal conditioning in 1.5 V–5.5 V battery-powered systems. It delivers 880 kHz gain bandwidth at 60 µA quiescent current, 500 µV max offset voltage (A-grade), 63 mA output drive at 5 V, and integrated shutdown control - enabling high-accuracy sensor front-ends and portable medical instrumentation.
For engineers reviewing the TSV630IQ2T datasheet, TSV630IQ2T pinout, TSV630IQ2T application, or TSV630IQ2T equivalent, key selection criteria include its 1.5 V minimum supply, 5 nA shutdown current, rail-to-rail I/O swing within 35 mV of rails, and guaranteed -40 °C to 125 °C operation - critical for automotive-grade portable diagnostics and low-voltage IoT sensor nodes.
Technical Context
The TSV630IQ2T employs complementary PMOS/NMOS input pairs to achieve true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and maintains phase reversal immunity across its full operating range. Its internal trimming ensures ±17% dispersion in supply current, directly stabilizing GBP (min 730 kHz), slew rate (min 0.25 V/µs), and large-signal gain (min 89 dB).
Shutdown is implemented via a dedicated SHDN pin that forces output into high-impedance state when pulled to VCC−, with turn-on/off times under 300 ns and leakage <1 nA over temperature. The device remains unity-gain stable driving capacitive loads ≤100 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - enables direct operation from single Li-ion, 2×AA, 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 wearable sensors and remote monitors. |
| Gain Bandwidth Product | 880 kHz typ - supports anti-aliasing and active filtering up to ~100 kHz with <1% gain error. |
| Input Offset Voltage | 500 µV max (A-grade) - ensures <0.1% measurement error in 500 mV full-scale medical transducer interfaces. |
| Output Drive Capability | 63 mA sink/source at VCC = 5 V - drives 80 Ω loads directly, eliminating buffer stages in analog output circuits. |
| Shutdown Current | 5 nA typ - reduces standby power to negligible levels in duty-cycled data loggers. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or piezoelectric sensor interfaces. |
| Operating Temperature | -40 °C to 125 °C - qualified for under-hood automotive and industrial edge-node deployments. |
Pinout & Package
TSV630IQ2T is housed in a 6-pin DFN package (1.2 mm × 1.3 mm, 0.4 mm pitch) with exposed thermal pad. Pin 1 is marked by a dot; the exposed pad must be connected to VCC− for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low logic: pull to VCC− to disable amplifier and reduce ICC to 5 nA; must not float. |
| 2 (IN−) | Inverting input | Differential node for feedback networks; rail-to-rail common-mode range supports single-supply configurations. |
| 3 (IN+) | Non-inverting input | High-impedance (1 pA bias) node for sensor signal routing; immune to phase reversal. |
| 4 (VCC−) | Negative supply / ground | Reference for all inputs/outputs; connects to exposed thermal pad for thermal dissipation. |
| 5 (OUT) | Amplifier output | Rail-to-rail swing (within 35 mV of rails into 10 kΩ); capable of 63 mA drive at 5 V. |
| 6 (VCC+) | Positive supply | Accepts 1.5–5.5 V; requires local 10 nF decoupling capacitor per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply 1.8 V systems - e.g., 0–1.8 V sensor output digitization without level shifters. |
| Integrated shutdown mode | Reduces total system standby current to nanoampere level while preserving fast wake-up (<300 ns) for event-triggered sensing. |
| Low input bias current (1 pA) | Eliminates significant voltage drop across >100 MΩ source impedances - essential for electrochemical and capacitive touch sensors. |
| Tight parameter dispersion | ±17% ICC variation ensures predictable GBP and slew rate across production lots - simplifies design margining for timing-critical filters. |
| Unity-gain stability | Operates stably as buffer or gain-of-one amplifier driving up to 100 pF - avoids need for external compensation in compact PCB layouts. |
Applications
| Medical Pulse Oximetry Front-End | Automotive Cabin Air Quality Sensor Interface |

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 |
|---|---|---|---|
| TSV621ICT | Lower power (29 µA), lower GBP (420 kHz), no shutdown function | Better suited for always-on sub-100 kHz sensor monitoring where shutdown is unnecessary | Select when maximizing battery life outweighs need for fast wake-up or higher bandwidth |
| TSV631IYCT | Same specs but dual-channel; no shutdown on second channel | Optimized for space-constrained dual-sensor systems (e.g., differential thermopile + ambient temp) | Choose for board-level integration savings where one channel requires shutdown and the other operates continuously |
Compared with TSV630IQ2T, TSV621ICT trades 47% lower quiescent current for 52% reduced bandwidth and loss of shutdown control - ideal for static sensor monitoring. TSV631IYCT retains identical per-channel performance but adds a second amplifier without shutdown, improving channel density at the cost of layout flexibility.

FAQ
What is the maximum capacitive load the TSV630IQ2T can drive without oscillation?
The TSV630IQ2T is unity-gain stable driving capacitive loads up to 100 pF with no external compensation. For larger loads, ST recommends adding a series resistor (Riso) at the output - values range from 10 Ω for 220 pF to 50 Ω for 1 nF, as validated in Figure 23 of the datasheet. Bench validation is required after selection.
Does the TSV630IQ2T require external components for shutdown functionality?
No external components are required for basic shutdown operation: pulling the SHDN pin to VCC− disables the amplifier and reduces supply current to 5 nA. However, a pull-down resistor (e.g., 100 kΩ) is recommended if the controlling GPIO cannot actively drive the pin low, preventing floating-state instability per Section 4.4 of the datasheet.
Can the TSV630IQ2T operate from a 1.5 V supply while maintaining rail-to-rail input performance?
Yes - the TSV630IQ2T is fully specified down to 1.5 V supply, with rail-to-rail input common-mode range extending from (VCC−) −0.1 V to (VCC+) +0.1 V. Input offset voltage remains ≤4.5 mV and GBP ≥730 kHz at 1.5 V, as confirmed in Table 3 and Figure 5 of the datasheet.
How does the exposed thermal pad on the DFN6 package affect thermal performance?
The exposed pad on the TSV630IQ2T's DFN6 package must be soldered to a PCB copper pour connected to VCC− to achieve the specified RthJA of 232 °C/W. Leaving it unconnected degrades thermal resistance by >40%, risking junction temperatures exceeding 150 °C under sustained 63 mA output loading per Section 5.1 mechanical data.
