STMicroelectronics TSV630AIQ1T

Overview

TSV630AIQ1T from STMicroelectronics is a rail-to-rail input/output, single-channel CMOS operational amplifier optimized for ultra-low-power, precision signal conditioning in battery-powered systems. It delivers 880 kHz gain bandwidth at 60 µA supply current (5 V), 500 µV max offset voltage (A-grade), 1 pA typical input bias current, and operates from 1.5 V to 5.5 V - enabling high-accuracy sensor front-ends in automotive body electronics and portable medical monitors.

For engineers reviewing the TSV630AIQ1T datasheet, TSV630AIQ1T pinout, TSV630AIQ1T application, or TSV630AIQ1T equivalent, this page provides verified electrical parameters, validated shutdown timing (300 ns turn-on), package-specific thermal resistance (232 °C/W for DFN6), and real-world design context for low-voltage, low-noise analog signal chains.

Technical Context

The TSV630AIQ1T integrates complementary PMOS/NMOS input pairs to achieve true rail-to-rail input operation across –0.1 V to V_CC+0.1 V, with no phase reversal. Its internal trimming ensures ±17% dispersion in supply current, directly stabilizing GBP (min 730 kHz) and slew rate (min 0.25 V/µs).

It features an active shutdown function controlled by a dedicated SHDN pin (VIH = 4.5 V, VIL = 0.5 V at 5 V), reducing quiescent current to 5 nA typ while placing output in high-impedance state. Unity-gain stability supports capacitive loads up to 100 pF without external compensation.

Key Specifications

Pinout & Package

TSV630AIQ1T is supplied in a 6-pin DFN (1.2 mm × 1.3 mm, 0.4 mm pitch) package with wettable flanks, rated for 232 °C/W junction-to-ambient thermal resistance. The exposed pad is electrically connected to V_CC– (GND) per ST's recommended layout.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-power, rail-to-rail op-amp applications.

Compared with TSV630AIQ1T, TSV621ICT trades 48% lower quiescent current for 52% less bandwidth and loss of shutdown control, while MCP6001T-E/OT offers pin compatibility but sacrifices 3× offset voltage and lacks automotive qualification - making TSV630AIQ1T the only option meeting strict AEC-Q100, low-offset, and fast-wake requirements simultaneously.

FAQ

What is the maximum capacitive load the TSV630AIQ1T can drive without oscillation?

The TSV630AIQ1T is unity-gain stable and can drive up to 100 pF capacitive load directly without external compensation. For larger loads, ST recommends adding a series resistor (e.g., 10–100 Ω) between the output and load, with values selected per Figure 23 in the datasheet. Stability must be verified experimentally and via simulation using ST's provided 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: tie to V_CC+ (≥4.5 V at 5 V supply) to enable, or to V_CC– (GND) to disable. Floating causes undefined behavior, potentially leading to erratic output states or increased current consumption. ST specifies IIH/IIL ≤10 pA, so standard 10–100 kΩ pull-up/down resistors are appropriate.

How does the rail-to-rail input architecture affect common-mode rejection at supply rails?

The TSV630AIQ1T uses complementary PMOS/NMOS input pairs, extending the common-mode range to (V_CC–) –0.1 V and (V_CC+) +0.1 V. However, CMRR degrades slightly near the transition point (~V_CC+ – 0.7 V), where both pairs operate simultaneously. At full rail, CMRR remains ≥55 dB (typ 80 dB), sufficient for most single-supply sensor interfaces but not for precision ratiometric measurements at extreme common-mode voltages.

Is the DFN6 package of TSV630AIQ1T compatible with reflow soldering per JEDEC J-STD-020?

Yes - the TSV630AIQ1T in DFN6 (1.2 × 1.3 mm) package is qualified for standard Pb-free reflow profiles per JEDEC J-STD-020D, with peak temperature up to 260 °C. Its wettable flanks support automated optical inspection (AOI) of solder joints. ST recommends using 10 nF decoupling capacitors placed <1 mm from V_CC+/V_CC– pins to ensure signal integrity during thermal cycling.
