Overview
The ADG704BRMZ is a CMOS analog multiplexer produced by Analog Devices Inc. This component is part of the ADG704 series, designed on an advanced submicron process that offers low power dissipation, high switching speed, low on-resistance, low leakage currents, and high bandwidths. The ADG704 is a 4-channel multiplexer that switches one of four inputs to a common output, controlled by 3-bit binary address lines (A0, A1, and EN). It operates from a single supply range of +1.8 V to +5.5 V, making it suitable for battery-powered instruments and compatible with modern DACs and ADCs from Analog Devices.
