The ADG731/ADG725 are monolithic, CMOS, 32-channel/ dual 16-channel analog multiplexers with a serially controlled 3-wire interface. The ADG731 switches one of 32 inputs (S1S32) to a common output, D. The ADG725 can be configured as a dual mux switching one of 16 inputs to one output, or a differential mux switching one of 16 inputs to a differential output. These mulitplexers utilize a 3-wire serial interface that is compatible with SPI, QSPITM, MICROWIRETM, and some DSP interface standards. On power-up, the Internal Shift Register contains all zeros and all switches are in the OFF state. These multiplexers are designed on an enhanced submicron process that provides low power dissipation yet gives high switching speed with very low on resistance and leakage currents. They operate from a single supply of 1.8 V to 5.5 V or a 2.5 V dual supply, making them ideally suited to a variety of applications. On resistance is in the region of a few ohms, is closely matched between switches, and is very flat over the full signal range.
