THS4531DGKEVM Evaluation Module
The THS4531DGKEVM is an evaluation module for the single THS4531 amplifier in the DGK [8-lead
VSSOP (MSOP)] 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 source, 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 single-ended
input with gain of 1 V/V to differential output at the device pins, which is converted to single-ended via a
transformer to the output. It can be easily configured for other functions, gains, and single- or split-supply
operation.
