THS6232RHF Evaluation Module
Description
This THS6232RHF evaluation module (EVM) 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 50Ω laboratory equipment on the inputs and
outputs. The amplifier is configured for a differential
input with a gain of 10V/V to a differential output. The
board includes jumpers to easily switch the device
between different bias modes and a potentiometer
to set the value of the IADJ pin. The EVM can be
easily configured for other gains and for single- or
split-supply operation. The output transformer and

resistors can be configured to present a 50Ω single-
ended output.
Features
•
Configured for split-supply operation and easily
modified for single supply
•
Default gain of 10V/V configuration can easily be
reconfigured for other gains
•
Designed for easy connection to standard 50Ω
input and output impedance test equipment
•
Quick setup board for THS6222 devices, with an
optional pad for VCM pin capacitor
•
Potentiometer and nearby resistors allow for
precise setting of IADJ pin, including for ultra-low
bias mode
