OPA818DRGEVM Evaluation Module
The OPA818DRGEVM is an evaluation module (EVM) for the single OPA818 in the DRG (8-pin WSON)
package. The OPA818DRGEVM is designed to quickly demonstrate the functionality and versatility of the
amplifier.
The EVM is ready to connect to power, signal sources, and test instruments by using onboard connectors.
The default amplifier configuration is a noninverting gain of 7 in a split-supply design. The EVM can be
easily configured for other gains and single-supply operation. Throughout this document the term
EVM is
synonymous with the OPA818DRGEVM .
1 Features
• Configured for split-supply operation and modified for single-supply.
• Default noninverting gain of 7 configuration is reconfigurable for other gains.
• Designed for connection to standard 50- Ω impedance test equipment.
• Inputs and outputs include subminiature version A (SMA) connectors.

2.1 Power Connections
The OPA818DRGEVM is equipped with banana jacks for easy power connection. The positive supply
input is labeled VCC, the negative supply input is labeled VEE, and ground is labeled GND.
2.1.1 Split-Supply Operation
To operate in a split-supply configuration, apply the positive supply voltage to VCC, the negative supply
voltage to VEE, and the ground reference from supply to GND.
2.1.2 Single-Supply Operation
To operate in a single-supply configuration, apply jumper VEE to GND and the positive supply voltage to
VCC. The inputs and outputs must be biased per the data sheet specifications for proper operation.
