« Last post by Noopy on Today at 02:59:50 am »When I designed my super low noise DC differential amplifier, I deliberately used the LTC1151 dual because separate chopper stabilized amplifiers would run at slightly different frequencies creating the potential for beat frequencies. Two separate dies are unlikely for this reason unless the clocks can be synchronized. Some of the older single chopper-stabilized parts have a clock pin which can be used for synchronization to avoid this problem.
The LTC1052 has a clock pin to synchronise them.
