The ADG732 switches one of thirty-two inputs (S1-S32) to a common output, D. The ADG725 can be configured as a dual mux switching one of sixteen inputs to one output or a differential mux switching one of sixteen inputs to a differential output. These mulitplexers utilize a 3-wire serial interface that is compatible with SPITM, QSPITM, MICROWIRETM and some DSP interface standards. On po...
