STEVAL-CCA010V1
Description
The demonstration board STEVAL-CCA010V1 is
designed to evaluate the TSH122 that is a video
buffer that uses a voltage feedback amplifier, with
an internal gain of 6 dB, an output rail-to-rail, an
internal input DC-shift and a SAG correction. A
power-down function allows switching to a sleep
mode with an ultra-low consumption.
The TSH122 features a 6th-order internal
reconstruction filter to attenuate the parasitic
frequency of 27 MHz from the clock of the video
DAC.
The TSH122 is a single operator available in a
tiny SC70 plastic package for space saving.
