GENERAL DESCRIPTION
closely matched between switches and very flat over the full signal The ADG726/ADG732 are monolithic, complementary metal range. These devices can operate equally well as either multiplexers oxide semiconductor (CMOS) 32-channel and dual 16-channel or demultiplexers and have an input signal range that extends analog multiplexers. The ADG732 switches one of 32 inputs (S1 to to the supplies. In the off condition, signal levels up to the S32) to a common output, D, as determined by the 5-bit binary supplies are blocked. All channels exhibit break-before-make address lines A0, A1, A2, A3, and A4. The ADG726 switches one switching action, preventing momentary shorting when switching of 16 inputs as determined by the 4-bit binary address lines A0, A1, channels. A2, and A3. The ADG726/ADG732 are available in a 48-lead LFCSP or a 48- On-chip latches facilitate microprocessor interfacing. The ADG726 lead TQFP. For functionally equivalent devices with serial interface, see the ADG725/ADG731. may also be configured for differential operation by tying CSA and CSB together.
