Overview
The ADG704BRM is a CMOS analog multiplexer produced by Analog Devices Inc. This device is designed on an advanced submicron process, offering low power dissipation, high switching speed, low on-resistance, low leakage currents, and high bandwidths. The ADG704BRM comprises four single channels and operates as a 4:1 multiplexer, switching one of four inputs to a common output based on 3-bit binary address lines and an enable pin. It is suitable for a wide range of applications due to its single supply operation from +1.8 V to +5.5 V and its compact 10-lead µSOIC or MSOP package.
