Overview

The DG442DVZ is a high-performance quad SPST analog switch designed for precision signal routing. It features four independent normally open (NO) switches that support wide supply ranges from 5V to 34V single-supply or +/-5V to +/-22V dual-supply. With a low charge injection of -1pC and high-speed switching transitions, it is optimized for high-fidelity data acquisition and instrumentation applications.

Why Choose This Part

This device offers significantly improved performance over industry-standard DG201A and DG202 switches, featuring lower leakage and faster switching speeds. Its TTL/CMOS compatible inputs simplify interfacing with 5V microcontrollers, while the robust 44V maximum supply rating provides substantial headroom for industrial transients.

Applications

Data Acquisition Systems
Used for input multiplexing and signal conditioning where low leakage and fast settling times are required.
Sample and Hold Circuits
Leverages the very low 4pF channel capacitance and -1pC charge injection to minimize voltage droop and pedestal errors.
Precision Audio Switching
Enables high-dynamic-range audio routing with minimal distortion thanks to the 85 Ohm max on-resistance and wide voltage rails.
Automatic Test Equipment (ATE)
Provides reliable signal path control in high-density testing environments requiring TSSOP-16 packaging.

Getting Started

Designers should ensure bypass capacitors are placed close to the V+ and V- pins to minimize noise during high-speed switching. When used in single-supply configurations, the V- pin must be tied to ground, and logic levels should be verified against the 5V to 34V supply rail to maintain proper threshold levels.
