Overview

The ADG707BRUZ is a low-voltage, CMOS analog multiplexer comprising two independent 8-channel differential channels. It operates from a single 1.8V to 5.5V supply and features a low on-resistance of 4.5 ohms max, making it ideal for high-accuracy signal switching in battery-powered applications.

Why Choose This Part

This multiplexer offers extremely low charge injection of 8pC to minimize transients during switching and a high 36MHz bandwidth for high-speed signal integrity. Its low 4.5 ohm on-resistance ensures minimal voltage drop and high linearity across the full signal range.

Applications

Data Acquisition Systems
Used to route multiple analog sensor signals to a single ADC input with minimal signal distortion.
Battery-Powered Instrumentation
Takes advantage of the ultra-low 1 microamp maximum supply current to extend battery life in portable meters.
Audio and Video Switching
Utilizes the 36MHz bandwidth and -80dB crosstalk performance for clean signal routing in multimedia systems.
Communication Systems
Employs break-before-make switching to prevent momentary shorting between input channels during transitions.

Getting Started

Designers should ensure the digital control inputs are driven by TTL or CMOS compatible logic levels for reliable operation. For prototyping, the 28-TSSOP package requires a breakout board or a custom PCB with a 0.65mm pin pitch and adequate decoupling capacitors placed near the VDD pin.
