The OPA2863DGKEVM is an evaluation module (EVM) for the dual-channel OPA2863 amplifier in the DGK (VSSOP-8) package. The OPA2863 is a low-power, unity-gain stable, rail-to-rail input and output (RRIO), voltage-feedback operational amplifier designed to operate over a power-supply range of 2.7 V to 12.6 V. The OPA2863DGKEVM is designed to quickly and easily demonstrate the functionality and versatility of the amplifier. The EVM is ready to connect to power, signal source, and test instruments through the use of onboard connectors. The EVM is configured for easy connection with common 50-Ω laboratory equipment at its inputs and outputs. Each amplifier is configured for single-ended inputs with a non-inverting signal gain of 1 V/V at the device output. The OPA2863DGKEVM has a total onboard load of 2 kΩ to each amplifier. The output resistor network converts the output to a 50-Ω impedance source. The evaluation module can be easily configured for other functions, gains, and single- or split-supply operation.
- Configured for split-supply operation and easily modified for single supply
- Configured for unity-gain non-inverting configuration and easily modified for inverting gain configuration
- Options to configure in different gains and active filter configurations through simple BOM change
- Simple interface to the inputs and outputs through the SMA connectors
