Hi,

 

We are using ADL5201 as ADC driver and we are using it in parallel mode. When the Latch pin is disabled (brought to high), will the VGA hold on to the previous gain value or Will the gain value be resetted. We are using multiple VGAs sharing common Gain control lines but individual Latch lines. If we program the Gain for one VGA and delatch the line (in order to program next VGA), will the first VGA retain the gain value?
