OPA2835DGS, OPA2836DGS EVM

The OPA2835DGS EVM is an evaluation module for the dual, OPA2835 in the DGS (10-lead MSOP)

package.

The OPA2836DGS EVM is an evaluation module for the dual, OPA2836 in the DGS (10-lead MSOP)

package.

The OPA2835DGS and OPA2836DGS EVMs are designed to quickly demonstrate the functionality and

versatility of the amplifier(s). The EVM is ready to connect to power, signal source, and test instruments

through the use of on-board connectors. The default amplifier configuration is non-inverting gain of 2

configuration and split supply. It can be easily configured for other gains, and single supply operation.

1 Features

• Configured for split supply operation and modified for single supply

• Default non-inverting gain of 2 configuration can be reconfigured for other gains

• Designed for connection to standard 50-Ω input/output impedance test equipment

• Inputs and Outputs include SMA connectors
