The ADG731 switches one of 32 inputs 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 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 switching speed with very low on resistance and leakage currents. They operate from a single supply of V to V or a ± 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. Information furnished by Analog Devices is believed to be accurate and reliable. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties that may result from its use. No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. Trademarks and registered trademarks are the property of their respective companies. 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.
