Overview

The TSV622AIST is a dual CMOS operational amplifier designed for low-power applications, operating with a typical supply current of only 29uA per channel at 5V. It features rail-to-rail input and output capabilities across a wide supply voltage range of 1.5V to 5.5V, making it ideal for battery-operated systems. The device is EMI hardened and maintains stability when driving capacitive loads up to 100 pF.

Why Choose This Part

The TSV622AIST offers an excellent balance between power consumption and precision with its low input bias current and rail-to-rail flexibility. Its EMI hardening provides robust performance in electrically noisy environments, while the ability to operate down to 1.5V ensures functionality even as battery voltages drop.

Applications

Battery-Powered Instrumentation
Utilizes the ultra-low 29uA supply current to extend operating life in portable handheld measurement tools.
Photodiode Amplification
Leverages the extremely low 1pA input bias current for precise signal conditioning of high-impedance sensors.
Active Filtering
Provides a 420 kHz gain bandwidth product suitable for low-frequency filtering in power-constrained sensor nodes.
Signal Conditioning
Used as a buffer or gain stage for microcontrollers in 1.8V, 3.3V, or 5V systems due to its rail-to-rail architecture.

Getting Started

For rapid prototyping, mount the MiniSO8 package onto a standard SMT-to-DIP adapter board for use with breadboards. Ensure a 0.1uF ceramic bypass capacitor is placed close to the VDD pin to maintain stability and minimize noise in sensitive analog signal paths.
