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 (S1–S32) to a common output, D. The ADG725 can be config- ured 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 com- patible with SPI® , QSPI™ , MICROWIRE™ , 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 switch- ing 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. These parts can operate equally well as either multiplexers or demultiplexers and have an input signal range that extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All channels exhibit break-before-make switching action, preventing momentary shorting when switching channels. The ADG731 and ADG725 are serially controlled 32-channel, and dual/differential 16-channel multiplexers, respectively. They are available in either a 48-lead LFCSP or TQFP package.
