The ADG759 is a low voltage, CMOS analog multiplexer comprising four differential channels. The ADG759 switches one of four differential inputs to a common differential output as determined by the 2-bit binary address lines A0 and A1. An EN input is used to enable or disable the device. When disabled, all channels are switched OFF.Low power consumption and operating supply range of 1.8 V to 5.5 V make the ADG759 ideal for battery-powered, portable instruments.

TThe ADG774A is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. The CMOS process provides low power dissipation yet offers high switching speed and low on resistance. The on resistance variation is typically less than 0.5 Ω over the input signal range.The bandwidth of the ADG774A is typically 400 MHz and this, coupled with low distortion (typically 0.3%), makes the part suitable for switching of high speed data signals.The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion. CMOS construction ensures ultralow power dissipation.The ADG774A operates from a single 3.3 V/5 V supply and is TTL logic-compatible. The control logic for each switch is shown in the truth table.These switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked.
