Key Features

  • Zero-drift architecture ensures near-zero offset voltage and drift over temperature
  • Rail-to-rail input/output (RRIO) maximizes dynamic range in low-voltage systems
  • Ultra-low noise: 7nV/√Hz typical, ideal for precision signal conditioning
  • Wide supply range: 1.8V to 5.5V single supply for portable and IoT designs
  • High CMRR: 100dB min / 112dB typical for excellent common-mode rejection

Applications

The OPA2378AIDCNR is well-suited for precision sensor signal conditioning in medical, industrial, and test equipment. Its zero-drift architecture and low noise make it ideal for thermocouple amplifiers, strain gauge bridges, and portable data acquisition systems. The wide supply range and rail-to-rail I/O also enable use in battery-powered IoT devices and wearable health monitors.
