Product details

Overview

TSV630ICT 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. It is used in portable medical sensors and low-voltage active filters.

For engineers reviewing the TSV630ICT datasheet, TSV630ICT pinout, TSV630ICT application, or TSV630ICT equivalent, key selection criteria include shutdown functionality, rail-to-rail I/O swing at sub-2 V operation, 1 pA input bias current for high-impedance sensor interfaces, and guaranteed unity-gain stability with 100 pF capacitive load.

Technical Context

The TSV630ICT integrates complementary PMOS/NMOS input pairs enabling true rail-to-rail input common-mode range (V_CC− − 0.1 V to V_CC+ + 0.1 V) without phase reversal. Its internal trimming ensures tight dispersion of DC/AC parameters - GBP min = 730 kHz and slew rate min = 0.25 V/µs are guaranteed across temperature.

Shutdown control is implemented via a dedicated SHDN pin requiring logic-low (≤0.5 V) to disable the amplifier and place output in high-Z state; turn-on/off times are 300 ns / 30 ns (5 V, RL = 2 kΩ). The device maintains 60 dB+ CMRR and 75 dB+ PSRR across its full 1.5–5.5 V 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), alkaline (1.5 V), or regulated 3.3 V/5 V rails
Quiescent Current	60 µA typ at 5 V - extends battery life in always-on sensor nodes; drops to 5 nA in shutdown
Gain Bandwidth Product	880 kHz typ - supports audio-band filtering and low-speed instrumentation amplification
Input Offset Voltage	500 µV max (A version) - ensures <1 mV error in 1× gain configurations with 2 V input span
Input Bias Current	1 pA typ - preserves signal integrity in pH electrodes, photodiode transimpedance stages, and piezoelectric sensors
Rail-to-Rail I/O	V_OH ≤ 35 mV from V_CC+, V_OL ≤ 35 mV from V_CC− (RL = 10 kΩ) - maximizes dynamic range in low-voltage ADC driver applications
Unity-Gain Stability	Stable with ≥100 pF capacitive load - eliminates need for external compensation in buffer configurations

Pinout & Package

TSV630ICT is supplied in SC70-6 (SOT323-6) package: 1.3 mm × 1.0 mm × 0.9 mm, 6-pin surface-mount, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
1 (IN+)	Non-inverting input	High-impedance node (1 pA bias); accepts signals from V_CC− − 0.1 V to V_CC+ + 0.1 V
2 (IN−)	Inverting input	Differential pair input; matched to Pin 1 for <500 µV offset
3 (V_CC−)	Negative supply	Ground reference for single-supply operation; connects to system GND
4 (SHDN)	Shutdown control	Active-low enable: ≤0.5 V disables amp; ≥4.5 V (5 V) enables; must not float
5 (OUT)	Amplifier output	Capable of ±63 mA sink/source (5 V); rail-to-rail swing into 10 kΩ
6 (V_CC+)	Positive supply	Accepts 1.5–5.5 V; requires local 10 nF decoupling per layout guidelines

Key Features

Feature	Design Value

Guaranteed unity-gain stability	Eliminates external compensation components in voltage-follower and active filter designs
Tight parameter distribution	±17% ICC spread ensures consistent GBP/SR across production lots - simplifies design validation
Extended temperature range	Specified from −40 °C to +125 °C - suitable for under-hood automotive and industrial motor control sensing
Rail-to-rail input transition	No phase reversal across full input range - prevents latch-up in precision comparator-like configurations

Applications

Portable ECG Monitor

Smart Smoke Detector Sensor Interface

Use Scenario: Amplifying microvolt-level biopotential signals from dry electrodes in a handheld ECG device powered by a CR2032 coin cell.

IC Role / Device Role / Timing Role: Precision DC-coupled front-end amplifier with rail-to-rail input to capture full electrode offset range and rail-to-rail output to drive 12-bit SAR ADC.

Use Value: 1 pA input bias avoids loading high-impedance electrode interface; 60 µA quiescent current enables >12-month battery life at 100 SPS sampling.

Use Scenario: Conditioning analog output from an electrochemical CO sensor in a battery-operated residential smoke alarm.

IC Role / Device Role / Timing Role: Low-drift transimpedance amplifier converting sensor current to voltage, followed by active low-pass filtering before ADC.

Use Value: 500 µV max offset minimizes calibration drift over temperature; shutdown mode cuts standby current to <100 nA during sleep cycles.

Wireless Temperature Node

Industrial Pressure Transmitter

Use Scenario: Signal conditioning for a silicon piezoresistive pressure sensor in a BLE-enabled HVAC sensor node.

IC Role / Device Role / Timing Role: Instrumentation amplifier input stage (gain = 100) with rail-to-rail output driving ADC reference buffer.

Use Value: 880 kHz GBW supports fast step response to pressure transients; 1.5 V minimum supply allows direct connection to buck-boost regulator output.

Use Scenario: Analog front-end for a 4–20 mA loop-powered pressure transmitter operating in harsh factory environments.

IC Role / Device Role / Timing Role: High-PSRR amplifier buffering bridge sensor output prior to voltage-to-current conversion.

Use Value: 102 dB PSRR rejects supply ripple from noisy 24 V loop power; −40 °C to +125 °C rating ensures reliability in enclosure-mounted installations.

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
TSV631ICT	No shutdown pin; 5-pin SC70 package; identical AC/DC specs except SHDN omission	Suitable where continuous operation is required and board space is constrained	Select when shutdown functionality is unnecessary and footprint reduction is prioritized
MCP6001UT-E/OT	Higher 100 µA IQ; no guaranteed unity-gain stability with >50 pF load; 200 µV max V_OS	Lacks robust capacitive drive capability; less suited for active filter buffers	Choose only if lower offset is critical and load capacitance remains <50 pF

Compared with TSV631ICT, TSV630ICT adds shutdown control at the cost of one pin and slightly larger package; versus MCP6001UT-E/OT, it offers superior capacitive drive, tighter parameter distribution, and lower quiescent current - making it preferable for battery-constrained, high-stability applications.

FAQ

What is the maximum capacitive load the TSV630ICT can drive without oscillation?

The TSV630ICT is unity-gain stable up to 100 pF capacitive load in follower configuration. For loads exceeding 100 pF, an in-series resistor (e.g., 10–100 Ω depending on capacitance) must be added at the output to maintain phase margin above 48°, as validated in Figure 23 of the datasheet.

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 either a direct connection to V_CC+ (to enable) or V_CC− (to disable). Leaving it unconnected risks undefined operation, increased current consumption, or output instability due to noise coupling; ST specifies VIH ≥ 4.5 V and VIL ≤ 0.5 V at 5 V supply.

Can the TSV630ICT operate from a 1.5 V supply while maintaining rail-to-rail input capability?

Yes - the TSV630ICT fully supports 1.5 V single-supply operation with rail-to-rail input (V_IN = 0 V to 1.5 V) and output (V_OUT = 0 V to 1.5 V, within 35 mV of rails). Electrical characteristics including GBP (730 kHz min) and V_OS (≤4.5 mV) are guaranteed across −40 °C to +125 °C at 1.5 V.

How does the TSV630ICT's input stage architecture prevent phase reversal?

The TSV630ICT uses dual complementary input pairs (PMOS + NMOS) with seamless crossover at ~0.7 V below V_CC+. Internal design ensures monotonic input offset vs. common-mode voltage (Figure 17–18), eliminating sign inversion - a failure mode common in single-pair rail-to-rail op-amps when inputs approach supply rails.
