Product details

Overview

TSV6393IST from STMicroelectronics is a micropower, rail-to-rail input/output quad operational amplifier in MiniSO10 package, featuring 2.4 MHz gain bandwidth, 60 µA supply current at 5 V, 1.5–5.5 V operation, shutdown mode (5 nA typ), and 800 µV max offset voltage (A version). It serves as a precision signal-conditioning front-end in battery-powered medical sensors and portable instrumentation.

For engineers reviewing the TSV6393IST datasheet, TSV6393IST pinout, TSV6393IST application, or TSV6393IST equivalent, key selection criteria include its guaranteed stability at gain ≥4 (non-inverting) or ≥11 (inverting), EMI-hardened performance (EMIRR up to 92 dB at 1.8 GHz), and extended -40 °C to 125 °C operating range for industrial-grade reliability.

Technical Context

The TSV6393IST integrates four independent CMOS op-amps with complementary PMOS/NMOS input stages enabling true rail-to-rail input (V_ICM = V_CC− − 0.1 V to V_CC+ + 0.1 V) and output swing within 35 mV of rails under 10 kΩ load. Its internal trimming ensures ±17% spread on supply current, directly stabilizing GBP (2.4 MHz typ), slew rate (1.1 V/µs), and large-signal gain (98 dB min).

Shutdown control is implemented via dedicated SHDN pins per amplifier, requiring logic-high enable (VIH = 2 V at V_CC = 5 V) and delivering 200 ns turn-on/20 ns turn-off times. The device is not unity-gain stable and requires minimum closed-loop gain of 4 (non-inverting) or 11 (inverting) with 100 pF capacitive load for phase margin ≥60°.

Key Specifications

Supply Voltage Range	1.5 V to 5.5 V - supports single-cell Li-ion, alkaline, and low-voltage industrial rails without level-shifting.
Gain Bandwidth Product	2.4 MHz typ - enables stable amplification of audio-band and sensor signals up to ~200 kHz at gain=12.
Supply Current per Amplifier	60 µA typ at 5 V - allows >1-year battery life in always-on wearable sensor nodes powered by CR2032.
Input Offset Voltage	800 µV max (A version) - ensures ≤0.8 mV error in 1 V full-scale medical ECG front-ends without trimming.
Shutdown Current	5 nA typ - reduces system standby power to nanoampere levels during sleep cycles in portable diagnostics.

Pinout & Package

TSV6393IST is housed in a 10-pin MiniSO (MSOP-10) package with 0.5 mm pitch, 3.0 mm × 4.9 mm footprint, and 0.86 mm typical height - optimized for space-constrained portable PCBs while maintaining thermal resistance of 113 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT1)	Amplifier 1 output	Rail-to-rail sourcing/sinking up to 40 mA at 5 V - drives ADC reference buffers or active filter stages directly.
2 (IN1−)	Amplifier 1 inverting input	1 pA bias current enables high-Z sensor interfaces (e.g., pH electrodes, piezoresistive bridges) without loading error.
3 (IN1+)	Amplifier 1 non-inverting input	Common-mode range extends 0.1 V beyond rails - accepts signals from thermocouples or resistive dividers referenced to ground or V_CC.
4 (V−)	Negative supply rail	Ground-referenced operation supported; no dual-supply requirement - simplifies single-supply system design.
5 (SHDN1)	Amplifier 1 shutdown control	CMOS-compatible logic input; pulls low to disable OUT1 and reduce ICC to 5 nA - enables per-channel power gating.
6 (SHDN2)	Amplifier 2 shutdown control	Independent control allows dynamic allocation of active channels in multi-sensor data loggers.
7 (IN2+)	Amplifier 2 non-inverting input	Matched input structure to Pin 3 - supports differential pair configurations with common-mode rejection >75 dB.
8 (IN2−)	Amplifier 2 inverting input	Paired with Pin 7 for precision instrumentation amplifiers using external gain-setting resistors.
9 (OUT2)	Amplifier 2 output	Electrically isolated from OUT1 - permits dual-path signal conditioning (e.g., AC-coupled bio-signal + DC-coupled temperature channel).
10 (V+)	Positive supply rail	Accepts 1.5–5.5 V; internal regulation ensures consistent GBP and SR across voltage range - eliminates supply scaling recalibration.

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables full dynamic range utilization in 1.8 V systems - captures 0–1.8 V sensor outputs without clipping or level-shifting circuitry.
EMI-hardened architecture	Rejects 400–2400 MHz RF interference at >61 dB - prevents false triggers in Bluetooth/Wi-Fi coexistence environments.
Ultra-low input bias current	1 pA typical - eliminates leakage-induced offset in high-impedance pH or ion-selective electrode circuits (>10 GΩ source impedance).
Guaranteed stability at gain ≥4	Eliminates need for external compensation in non-inverting active filters - reduces BOM count and layout area.
Extended temperature range	Validated operation from -40 °C to 125 °C - supports deployment in automotive cabin modules and industrial PLC analog I/O cards.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV6393AIST	Lower max offset voltage (1 mV vs. 2.2 mV over temp), same package and pinout	Better DC accuracy required in precision medical calibration paths	Select when V_IO drift <2.2 µV/°C is critical; otherwise standard TSV6393IST suffices for general-purpose sensing.
MCP6004-E/ST	Unity-gain stable, lower GBP (1 MHz), higher supply current (100 µA), SO-14 package	Requires no minimum gain; suited for buffer-only roles where simplicity outweighs power efficiency	Choose only if unity-gain stability is mandatory and 40 µA extra current per channel is acceptable in battery budget.

Compared with TSV6393IST, the TSV6393AIST improves DC precision at identical power and size, while the MCP6004 trades 40% higher current and larger footprint for guaranteed unity-gain operation - making TSV6393IST optimal for gain-configured, space- and power-constrained sensor front-ends.

FAQ

What is the minimum recommended gain for stable operation of TSV6393IST?

The TSV6393IST requires a minimum closed-loop gain of 4 in non-inverting configuration or 11 in inverting configuration when driving a 100 pF capacitive load, as verified by phase margin ≥60° testing per DS6635 Rev 4. This is due to its decompensated internal architecture optimized for 2.4 MHz GBP at 60 µA.

Can TSV6393IST operate from a 1.5 V supply?

Yes - the TSV6393IST is fully specified from 1.5 V to 5.5 V, with characterized performance at 1.5 V, 1.8 V, 3.3 V, and 5 V. At 1.5 V, it delivers 2 MHz GBP, 0.7 V/µs slew rate, and maintains rail-to-rail input/output swing, enabling single-cell alkaline or lithium primary battery operation.

How does the shutdown function behave electrically?

When SHDN is pulled low (≤0.8 V at V_CC = 5 V), the amplifier output enters high-impedance state, supply current drops to 5 nA typ, and turn-off completes within 20 ns. Pulling SHDN high (≥2 V) restores full operation in 200 ns. The SHDN pin must never float and must be actively driven to V_CC or ground.

Is TSV6393IST suitable for driving capacitive loads like ADC inputs?

Yes - with proper layout: place a 10 nF decoupling capacitor near each supply pin, use short traces, and limit capacitive load to ≤100 pF. For heavier loads (>100 pF), add a 22 Ω isolation resistor between amplifier output and ADC input to maintain stability and prevent peaking, as confirmed in Figure 5–7 of DS6635.
