Product details

Overview

TSV6290ILT from STMicroelectronics is a micropower single CMOS operational amplifier with rail-to-rail input and output, 1.3 MHz gain bandwidth product, 29 µA typical supply current, and integrated shutdown control. It operates from 1.5 V to 5.5 V and supports extended temperature range (–40 °C to +125 °C), making it suitable for precision signal conditioning in ultra-low-power battery-powered sensor nodes.

For engineers reviewing the TSV6290ILT datasheet, TSV6290ILT pinout, TSV6290ILT application, or TSV6290ILT equivalent, key selection criteria include shutdown functionality, 800 µV max input offset voltage (A-grade), 1 pA typical input bias current, stability at gain ≥4, and SOT23-6 package compatibility with high-density portable PCB layouts.

Technical Context

The TSV6290ILT uses complementary PMOS/NMOS input stages 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 compensation ensures stability only at closed-loop gains ≥4 (non-inverting) or |G| ≥ 3 (inverting), with 60° phase margin at 100 pF load.

Shutdown is controlled via a dedicated SHDN pin requiring logic-high (≥1.3 V at 1.8 V V_CC, ≥4.5 V at 5 V) for enable and logic-low (≤0.5 V) for disable, reducing quiescent current to 5 nA typical while placing output in high-impedance state. Turn-on/turn-off times are 300 ns and 30 ns respectively under 5 kΩ load.

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, alkaline, or coin-cell batteries without regulation.
Quiescent Current	29 µA typical - extends battery life in always-on sensing nodes; drops to 5 nA in shutdown mode.
Gain Bandwidth Product	1.3 MHz typical at 5 V - supports low-frequency precision amplification (e.g., sensor bridges, thermocouples) with minimal power penalty.
Input Offset Voltage	800 µV max (A version) - ensures <0.1% error in 0.8 V full-scale measurements without trimming.
Input Bias Current	1 pA typical - preserves signal integrity in high-impedance sources (e.g., pH electrodes, photodiodes).
Rail-to-Rail I/O	Input range: V_CC– – 0.1 V to V_CC+ + 0.1 V; output swing within 35 mV of rails at 10 kΩ - maximizes dynamic range in low-voltage systems.
ESD Rating	4 kV HBM - withstands handling and board-level electrostatic discharge in industrial and medical environments.

Pinout & Package

SOT23-6 package: 1.45 mm × 1.75 mm × 1.30 mm body, 0.95 mm lead pitch, ECOPACK®-compliant, surface-mountable with standard reflow profile.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (–)	Differential input node; requires matched trace impedance in high-precision layouts to minimize CMRR degradation.
2	Non-inverting Input (+)	Differential input node; common-mode range extends beyond rails by 0.1 V, enabling ground-referenced sensor interfacing.
3	V_CC– (Ground)	Power return path; must be connected to low-impedance ground plane with local 10 nF decoupling capacitor.
4	Output	Class-AB output stage; drives resistive loads ≥5 kΩ directly; capacitive loads >20 pF require external isolation resistor.
5	V_CC+ (Supply)	Positive supply rail; accepts 1.5–5.5 V; sensitive to ripple-requires dedicated 10 nF ceramic capacitor per supply pin.
6	SHDN	Active-low shutdown control; must be hard-wired to V_CC+ or V_CC–; floating state causes undefined operation and increased leakage.

Key Features

Feature	Design Value
Micropower shutdown mode	5 nA typical ICC in shutdown - reduces system standby power to nanoampere level for multi-year battery operation.
Rail-to-rail input architecture	Two complementary differential pairs eliminate input stage clipping - enables accurate amplification of signals near supply rails (e.g., 0–1.8 V ADC references).
Stable gain configuration	Guaranteed phase margin ≥60° at G ≥ 4 - eliminates need for external compensation in most sensor interface circuits.
High ESD tolerance	4 kV HBM rating - meets IEC 61000-4-2 Level 2 for handheld medical devices and portable instrumentation.
Precision DC performance	2 µV/°C offset drift and 79 dB min CMRR - maintains accuracy across automotive and industrial temperature ranges without recalibration.

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
TSV6291ILT	No shutdown pin; SOT23-5 package; identical electrical specs except missing SHDN function.	Used where space is tighter (SOT23-5 vs SOT23-6) and continuous operation is required.	Select when shutdown is unnecessary and PCB real estate is constrained-same precision, lower pin count.
MAX4477ASA+	Higher supply current (120 µA), wider GBW (10 MHz), no shutdown, SO-8 package.	Targeted at higher-speed active filtering where bandwidth outweighs power budget.	Choose only if >1.3 MHz GBW is mandatory; otherwise TSV6290ILT delivers superior µA/MHz efficiency.

Compared with TSV6291ILT, the TSV6290ILT adds critical shutdown control at the cost of one extra pin and slightly larger footprint; versus MAX4477ASA+, it trades bandwidth for 4× lower quiescent current and integrated power gating-making it optimal for energy-constrained edge sensing.

FAQ

What is the minimum stable gain configuration for TSV6290ILT?

The TSV6290ILT is not unity-gain stable and requires a minimum closed-loop gain of 4 in non-inverting configurations or |G| ≥ 3 in inverting configurations to maintain ≥60° phase margin. This is enforced by internal compensation optimized for micropower operation; using lower gains risks oscillation unless external compensation is added.

Can TSV6290ILT drive capacitive loads directly?

TSV6290ILT can drive up to 20 pF capacitive load stably with gain ≥4. For loads >20 pF, an isolation resistor (typically 10–100 Ω) must be placed between amplifier output and capacitance to prevent peaking and ringing. The device's low internal compensation capacitance makes it fast but sensitive to capacitive loading.

How does the SHDN pin behave during power-up?

The SHDN pin must be actively driven high (≥1.3 V at 1.8 V supply) after V_CC stabilizes; leaving it floating or unpowered during startup may cause erratic turn-on behavior or excessive current draw. ST recommends tying SHDN to V_CC via a pull-up resistor or controlling it with a GPIO that asserts after power sequencing completes.

Is TSV6290ILT compatible with SC70-6 footprint?

No-TSV6290ILT is specified only in SOT23-6 package (ordering code ILT). While SC70-6 and SOT23-6 share same pin count, their mechanical dimensions differ significantly: SOT23-6 has 2.80–3.05 mm length and 1.50–1.75 mm width, whereas SC70-6 measures 1.80–2.20 mm × 1.15–1.35 mm. Using SC70-6 footprint would cause solder joint misalignment and open circuits.
