Product details
Overview
TSV630IQ1T 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 portable medical sensors and low-voltage active filters.
For engineers reviewing the TSV630IQ1T datasheet, TSV630IQ1T pinout, TSV630IQ1T application, or TSV630IQ1T equivalent, key selection criteria include shutdown functionality, rail-to-rail operation down to 1.5 V, guaranteed 730 kHz min GBP, 0.25 V/µs min slew rate, and automotive-qualified (-40 °C to 125 °C) performance with 1 pA input bias current.
Technical Context
The TSV630IQ1T 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 DC/AC parameters-supply current variation ±17%, with minimum GBP (730 kHz) and slew rate (0.25 V/µs) guaranteed across temperature.
It integrates a dedicated SHDN pin that places output in high-impedance state when pulled low (VCC−), achieving 5 nA shutdown current. The amplifier remains unity-gain stable driving capacitive loads ≤100 pF and supports resistive loads ≥2 kΩ while maintaining THD <0.0017% at 1 kHz, 2 VPP output.
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, NiMH, or 3.3 V/5 V rails without regulation. |
| Quiescent Current | 60 µA typ at 5 V - extends battery life in always-on sensor front-ends and portable instrumentation. |
| Gain Bandwidth Product | 880 kHz typ (730 kHz min) - supports stable amplification of audio-band and low-speed sensor signals with minimal power penalty. |
| Input Offset Voltage | 500 µV max (A version) - ensures sub-mV DC accuracy in precision transducer interfaces and medical analog front-ends. |
| Input Bias Current | 1 pA typ - minimizes voltage error in high-impedance pH, photodiode, or piezoelectric sensor circuits. |
| Shutdown Current | 5 nA typ - reduces system standby power by >99.99% versus active mode, critical for energy-harvesting nodes. |
| Rail-to-Rail I/O | Input: VCC− −0.1 V to VCC+ +0.1 V; Output: within 35 mV of rails (RL = 10 kΩ) - maximizes dynamic range in low-voltage ADC driver applications. |
Pinout & Package
TSV630IQ1T is packaged in a 6-pin DFN (1.2 mm × 1.3 mm, 0.4 mm pitch) with wettable flanks, optimized for space-constrained PCB layouts and automated optical inspection. The exposed pad is electrically connected to VCC− and must be soldered for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SHDN) | Shutdown control input | Active-low logic input; pull to VCC− to disable amplifier and reduce supply current to 5 nA. |
| 2 (IN−) | Inverting input | Differential input node; 1 pA bias current enables high-Z sensor interfacing without loading error. |
| 3 (IN+) | Non-inverting input | Differential input node; rail-to-rail common-mode range supports full-supply-swing signal acquisition. |
| 4 (VCC−) | Negative supply / ground | Reference return path; also connects to exposed thermal pad for improved thermal dissipation. |
| 5 (OUT) | Amplifier output | Capable of sourcing/sinking 63 mA at 5 V; rail-to-rail swing ensures maximum utilization of ADC input range. |
| 6 (VCC+) | Positive supply | Accepts 1.5–5.5 V; internal regulation ensures stable performance across battery discharge profile. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40 °C to 125 °C) - qualified for under-hood and ADAS sensor signal conditioning. |

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 |
|---|---|---|---|
| TSV631IQ1T | No shutdown pin; identical AC/DC specs except SHDN omission. | Suitable where continuous operation is required and board space allows removal of SHDN routing. | Select when shutdown functionality is unnecessary-reduces BOM count and layout complexity. |
| TSV621ICT | Lower power (29 µA), lower speed (420 kHz GBP), no shutdown. | Better for ultra-long-life applications where bandwidth <500 kHz suffices (e.g., slow thermistor readout). | Choose for sub-30 µA systems trading bandwidth for >2× longer battery life; not pin-compatible. |
Compared with TSV630IQ1T, TSV631IQ1T removes shutdown capability but retains identical precision and drive strength, while TSV621ICT sacrifices 52% bandwidth and all shutdown control to achieve 52% lower quiescent current-making it optimal only for static-signal, extreme-low-power use cases.

FAQ
What is the maximum capacitive load the TSV630IQ1T can drive without external compensation?
The TSV630IQ1T is unity-gain stable driving capacitive loads up to 100 pF with no external components. For larger loads, an in-series resistor (e.g., 10–100 Ω depending on CL) must be added at the output to maintain phase margin above 48°, as confirmed in Figure 23 of the datasheet and validated in SPICE simulations using ST's macromodel.
Does the SHDN pin require a pull-up resistor, and what happens if left floating?
Yes-the SHDN pin must never be left floating. It requires a defined logic level: tied to VCC+ to enable operation or to VCC− to enter shutdown. Leaving it unconnected risks undefined output state, increased current consumption, or oscillation due to noise coupling. A 100 kΩ pull-up to VCC+ is recommended for default-enable configurations.
How does the TSV630IQ1T perform at 1.5 V supply, and is it fully specified there?
While full electrical characteristics are guaranteed at 1.8 V, 3.3 V, and 5 V, the TSV630IQ1T operates functionally down to 1.5 V with verified performance: GBP remains >700 kHz, ICC drops to ~40 µA, and rail-to-rail output swing is maintained within 50 mV of rails. Characterization curves (Figures 5, 14, 15) confirm stable behavior across this extended low-voltage range.
Is the exposed thermal pad on the DFN6 package electrically connected, and how should it be handled?
Yes-the exposed pad on the TSV630IQ1T's DFN6 (1.2 × 1.3 mm) package is internally connected to VCC−. It must be soldered to a PCB copper pour tied to the VCC− net for both thermal dissipation (Rthja = 232 °C/W) and electrical stability. Floating or isolated pads cause degraded PSRR, increased thermal resistance, and potential parametric shift at high ambient temperatures.
