ADG1434YCPZ-REEL7

High-Performance, Low-Ron iCMOS Analog Switch for Signal Routing

Product Description

Product Overview

The ADG1434YCPZ-REEL7 is a quad single-pole, double-throw (SPDT) analog switch designed for high-performance signal routing and multiplexing in industrial and instrumentation systems. Built with Analog Devices’ iCMOS process, it supports wide supply voltages and low on-resistance with excellent flatness, enabling low distortion and robust operation across a variety of signal environments. The device is ideal for data acquisition front ends, audio/video routing, automatic test equipment, and other mixed-signal applications.

Key Features

Low on-resistance: ≤ 4.7 Ω (max @ 25 °C)
Excellent on-resistance flatness (~0.5 Ω)
Supports single supply (5 V–16.5 V) and dual supply (±4.5 V–±16.5 V)
Rail-to-rail signal range
3 V logic-compatible inputs
Break-before-make switching action to prevent shorts
High bandwidth (~200 MHz) with fast switching
Available in compact LFCSP-20 (4 × 4 mm) package
Wide industrial temperature range –40 °C to +125 °C

Applications

Data acquisition and instrumentation front ends
Audio and video signal routing
Automatic test equipment (ATE)
Relay replacement in industrial systems
Communication signal switching
Portable and battery-powered systems
Temperature and sensor measurement systems
