Product details
Overview
TSV6292AILT from STMicroelectronics is a dual micropower CMOS operational amplifier with rail-to-rail input and output, 1.3 MHz gain bandwidth product, 29 µA typical supply current per amplifier, and operation down to 1.5 V supply voltage. It is designed for precision signal conditioning in ultra-low-power battery-powered systems such as portable medical sensors and wearable health monitors.
For engineers reviewing the TSV6292AILT datasheet, TSV6292AILT pinout, TSV6292AILT application, or TSV6292AILT equivalent, key selection criteria include its guaranteed minimum gain stability of +4 (non-inverting), 800 µV max input offset voltage (A-grade), shutdown capability (not applicable to TSV6292 variant), EMI hardening, and extended -40°C to +125°C operating range.
Technical Context
The TSV6292AILT employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) and rail-to-rail output swing (within 35 mV of rails into 10 kΩ). Its internal compensation requires minimum non-inverting gain ≥ +4 or inverting gain ≤ −3 for stability with 100 pF load.
It delivers 0.5 V/µs slew rate at 5 V supply, 80 dB large-signal voltage gain, and 77 nV/√Hz input voltage noise at 1 kHz. EMI rejection exceeds 85 dB at 900 MHz, and input bias current is 1 pA typical - critical for high-impedance sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.5–5.5 V - enables direct use with single-cell Li-ion (3.0–4.2 V), alkaline (1.5 V), or coin-cell (3 V) power sources without regulation. |
| Gain Bandwidth Product | 1.3 MHz typ - supports audio-band filtering (e.g., 20 kHz anti-aliasing) while maintaining <30 µA per op-amp quiescent current. |
| Input Offset Voltage | ≤800 µV max (A-grade) - ensures ≤0.8 mV DC error in 1× gain sensor buffers, critical for sub-millivolt biomedical signal integrity. |
| Rail-to-Rail I/O | Input: VCC−−0.1 V to VCC++0.1 V; Output: within 35 mV of rails into 10 kΩ - maximizes dynamic range in low-voltage systems. |
| Input Bias Current | 1 pA typ - permits use with >1 GΩ source impedances (e.g., pH electrodes, piezoelectric sensors) without significant DC error. |
| EMI Rejection Ratio | 85 dB at 900 MHz - suppresses cellular band interference in portable wireless medical devices without external shielding. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin modules, industrial edge sensors, and implantable device peripherals. |
Pinout & Package
TSV6292AILT is packaged in MiniSO-8 (ECOPACK® compliant), a 3 mm × 3 mm, 0.65 mm pitch surface-mount package optimized for space-constrained portable designs.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | In1− | Inverting input of amplifier 1 - connects to feedback network in inverting configurations or reference node in differential setups. |
| 2 | In1+ | Non-inverting input of amplifier 1 - interfaces directly with high-impedance sensors (e.g., thermopiles, strain gauges). |
| 3 | VCC− | Negative supply rail - must be tied to ground in single-supply operation; decoupling capacitor required adjacent to this pin. |
| 4 | Out1 | Output of amplifier 1 - drives ADC inputs, filters, or low-power transducers; rail-to-rail swing enables full utilization of 12-bit+ ADC range. |
| 5 | Out2 | Output of amplifier 2 - independent channel for dual-path signal processing (e.g., differential pair amplification or active filter stages). |
| 6 | In2− | Inverting input of amplifier 2 - used for second sensor channel or feedback path in composite amplifier topologies. |
| 7 | In2+ | Non-inverting input of amplifier 2 - matches Pin 2's high-impedance, low-bias characteristics for matched dual-channel performance. |
| 8 | VCC+ | Positive supply rail - accepts 1.5–5.5 V; requires local 10 nF ceramic decoupling to maintain stability and EMI immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | CMVR extends 0.1 V beyond both supply rails - eliminates level-shifting circuitry in single-supply data acquisition systems. |
| Micropower operation | 29 µA per amplifier at 1.8 V - enables >1-year battery life in coin-cell-powered IoT nodes with 10-second wake-up intervals. |
| A-grade precision | 800 µV max Vio over temperature - reduces calibration burden in factory-trimmed portable instrumentation. |
| EMI-hardened architecture | 85 dB rejection at 900 MHz - meets EN 61000-4-3 Level 3 immunity without layout-level countermeasures. |
| Stable at gain ≥ +4 | Guaranteed phase margin ≥60° with 100 pF capacitive load - simplifies filter design in anti-aliasing and sensor interface applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV6222ILT | Lower GBP (420 kHz), unity-gain stable, same 29 µA ICC, no A-grade option (max Vio = 1.5 mV) | Suitable for DC-coupled sensor buffers where bandwidth <500 kHz suffices; lacks precision needed for medical-grade signal chains. | Select when stability at G = 1 is mandatory and offset voltage <1 mV is not required. |
| MAX4477ASA+ | Higher ICC (60 µA), higher GBP (10 MHz), lower Vio (125 µV max), SO-8 only, no EMI hardening | Better for high-speed, high-precision applications (e.g., portable oscilloscope front-ends); consumes >2× power and lacks RF immunity. | Select when sub-200 µV offset and multi-MHz bandwidth justify 2× current draw and added EMI mitigation effort. |
Compared with TSV6292AILT, TSV6222ILT trades bandwidth and precision for unconditional stability, while MAX4477ASA+ delivers superior AC/DC performance at significantly higher power and without integrated EMI protection - making TSV6292AILT optimal for battery-limited, RF-noisy, precision analog sensing where 1.3 MHz and 800 µV are sufficient.

FAQ
Is TSV6292AILT unity-gain stable?
No. The TSV6292AILT is not unity-gain stable and requires minimum non-inverting gain of +4 or inverting gain of −3 for stable operation with 100 pF capacitive load. This is confirmed in Table 4 and Section 4.6 of the datasheet, which specifies stability conditions and recommends TSV622x or TSV63x series for unity-gain applications.
Does TSV6292AILT have a shutdown pin?
No. The TSV6292AILT is the dual-channel version without shutdown functionality. Shutdown pins are present only on TSV6293 (dual with two SHDN pins) and TSV6295 (quad with four SHDN pins), as explicitly stated in Table 1 and Section 4.5 of the datasheet.
What is the maximum capacitive load the TSV6292AILT can drive stably?
The TSV6292AILT is characterized for stable operation with up to 100 pF capacitive load when used in minimum gain configurations (+4 non-inverting or −3 inverting) and with 10 kΩ resistive load, as verified in Figure 5–7 and Section 4.6. Driving larger capacitance requires external isolation resistor or gain adjustment.
Can TSV6292AILT operate from a 1.5 V supply?
Yes. The device is fully specified from 1.5 V to 5.5 V supply voltage, with electrical characteristics guaranteed at 1.8 V, 3.3 V, and 5 V - and validated down to 1.5 V in characterization curves (Figures 2–4, 14–15). Its rail-to-rail I/O enables full dynamic range utilization even at 1.5 V.
