ADG774BRQ-500RL7

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG774BRQ-500RL7 is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs, housed in a 16-lead Shrink Small Outline Package (QSOP). It operates from a single 3 V or 5 V supply and features a typical on resistance of 2.2 Ω with a flatness of 0.5 Ω. The component provides a –3 dB bandwidth of 240 MHz and exhibits very low distortion of 0.5%. Switching times are typically 7 ns for turn-on and 4 ns for turn-off. Quiescent supply current is typically 1 nA, and the device supports an automotive temperature range from –40°C to +125°C.
