The LMH2832EVM-50 evaluation module (EVM) is used to evaluate the dual LMH2832, digitally-controlled
variable gain amplifier (DVGA) in a 40-pin VQFN package. The EVM is used to easily demonstrate the
functionality and performance of LMH2832 across all the gain settings in a 50-Ω input environment. The
EVM is ready to connect to power supplies, signal source, USB, and test instruments through the use of
onboard connectors. By default, the LMH2832EVM powers up to the 10-dB gain setting with the board
supporting only single-supply operation. A USB connector on the EVM facilitates programming of the
DVGA gain registers using an FTDI USB-to-SPI bus translator chip.
