OPA862 evaluation module


Order now


The OPA862DEVM is an evaluation module for the single OPA862 amplifier in the D package. This evaluation module is designed to quickly and easily demonstrate the functionality and versatility of the amplifier. The EVM is ready to connect to power, signal sources, and test instruments through the use of onboard connectors. The EVM comes configured for easy connection with common 50-Ω laboratory equipment on its inputs and outputs. The amplifier is configured for a single-ended input with a gain of 4 V/V to a differential output at the device pins, which is converted to single-ended via a transformer to the output. The EVM can be easily configured for other gains and for single- or split-supply operation. The OPA862DEVM has a 2-kΩ onboard load for the amplifier. The output transformer and resistor network converts this load to a 50-Ω, single-ended output.

  • Single-ended high impedance input with differential output
  • Configurable gain resistors with optional additional feedback connection
  • Output transformer included to interface with single-ended test equipment
  • Fully configurable power-down and reference voltage inputs
