Overview

The DG409DYZ is a high-performance CMOS analog multiplexer featuring two independent 4-channel differential configurations. Designed as a modern upgrade to the industry-standard DG509A, it offers improved switching speeds and significantly lower charge injection of just 20pC. This device is compatible with both TTL and CMOS logic levels and supports a wide dual-supply operating range from +/-5V to 20V.

Why Choose This Part

The DG409DYZ provides high-speed switching with maximum Ton and Toff times of 150ns, ensuring responsive performance in real-time systems. Its high voltage tolerance up to 34V VDD and low 100-Ohm on-resistance make it a robust choice for industrial-grade signal conditioning. Furthermore, the 16-SOIC surface mount package offers a compact footprint without sacrificing thermal stability or power handling.

Applications

Precision Data Acquisition
Used to switch multiple sensor inputs into a single ADC while maintaining signal integrity with low leakage current.
Audio Signal Routing
Excels in audio switching systems due to low distortion and wide supply rails that accommodate large signal swings.
Sample and Hold Circuits
The low 20pC charge injection minimizes voltage errors during transition in precision analog processing stages.
Automatic Test Equipment
Enables reliable routing of test signals in high-density automated measurement systems across a wide temperature range.

Getting Started

To evaluate this multiplexer, ensure all unused inputs are tied to an appropriate rail to prevent noise coupling. Proper decoupling capacitors (0.1uF ceramic) should be placed as close as possible to the V+ and V- pins. Design the PCB layout with short signal traces to minimize parasitic capacitance, which is critical for maintaining the 150ns switching performance.
