Product Details

The AD8273 is a low distortion, dual-channel amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier (G = ½ or 2), inverting amplifier (G = ½ or 2), or noninverting amplifier (G = 1½ or 3).

The AD8273 operates on both single and dual supplies and only requires 2.5 mA maximum supply current for each amplifier. It is specified over the industrial temperature range of −40°C to +85°C and is fully RoHS compliant.


  • ADC drivers
  • High performance audio
  • Instrumentation amplifier building blocks
  • Level translators
  • Automatic test equipment
  • Sine/cosine encoders
