The OPA2188AIDR from Texas Instruments (TI) is a dual-channel, zero-drift precision operational amplifier designed for applications requiring high DC accuracy and long-term stability. Its auto-zero technology helps minimize input offset voltage and offset drift over time and temperature.
Featuring low noise, high DC precision, rail-to-rail output, and a wide supply voltage range, the OPA2188AIDR is suitable for precision analog signal conditioning and measurement systems. It operates from a 4V to 36V single supply or ±2V to ±18V dual supplies and comes in an 8-pin SOIC surface-mount package for convenient PCB integration and automated assembly.
