The ADG731BSUZ is a 32-channel Monolithic CMOS Analogue Multiplexer that switches one of 32 inputs (S1-S32) to a common output, D. It utilizes a 3-wire serial interface that is compatible 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. This multiplexer is designed on an enhanced submicron process that provides low power dissipation yet gives high switching speed, very low on resistance and leakage currents. On-resistance is in the region of a few ohms and is closely matched between switches and very flat over the full signal range. The ADG731 can operate equally well as either multiplexer or demultiplexer 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.
