EPAD op-amps cost no more than conventional devices and may ultimately offer improved reliability and considerable cost savings by eliminating mechanical trim pots and manual trimming.
Maximum speed, offset adjustment, current max, and gain can be set via trim pots or alternatively set via RS232 or a CAN bus.
