ADG794BRQZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG794BRQZ is a monolithic CMOS device comprising four independent 2:1 multiplexers/demultiplexers with high-impedance outputs. It operates from a single 3.3 V or 5 V supply and features a typical bandwidth of 300 MHz. The on-resistance is typically 5 Ω at 5 V and 7 Ω at 3.3 V, with an on-resistance flatness of 0.7 Ω. Switching times are fast, with tON typically 7 ns and tOFF typically 5 ns at 5 V. Quiescent supply current is typically 1 nA. The device includes ESD protection rated at 2 kV HBM, 200 V MM, and 1 kV FICDM. It is housed in a 16-lead QSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The base part number ADG794BRQZ indicates tube packaging, while suffixes such as -REEL or -RL7 denote reel packaging. Confirm RoHS compliance status via the 'Z' designation if required by procurement specifications. Ensure the industrial temperature range meets system requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low insertion loss and high bandwidth in analog signal routing. Verify that the single-supply voltage matches the system's 3.3 V or 5 V rails. Consider the break-before-make switching action for circuit timing. Ensure input signal ranges remain within the specified limits relative to the supply voltage to maintain performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG794 belongs to Analog Devices' family of low-voltage analog switches. It is designed for general-purpose signal routing where low distortion and high speed are critical. The BRQZ variant specifies the industrial temperature range and the QSOP package type. It serves as a solution for multiplexing multiple analog sources into a single destination.
