Evaluation Module for Zero-Drift, High Voltage Programmable Gain Amplifier


Order now


The PGA281EVM provides basic functional evaluation of the PGA281, a high-precision instrumentation amplifier with pin-programmable gain, attenuation, and error detection.

  • Onboard power management circuitry generates all required power-supply rails from one split-supply input
  • DIP switch allows easy setting of pin-programmable gain
  • Error flag LED provides visual feedback of any detected error condition
  • Easy access to pertinent nodes with test points, BNC connectors, and banana jacks
  • Component footprints allow multiple filtering configurations
