Présentation

Description

DG409DY is a variant in the DG409 family of CMOS analog switches. It is an IC used to route or isolate analog signals by closing or opening a bidirectional connection between two I/O pins under a digital control input.
Key points:
- Acts as a bidirectional analog switch (on/off under control).
- Used for signal routing in instrumentation, data acquisition, audio/video, and front-end switching.
- The “DY” suffix typically denotes a specific package/pinout variant from the manufacturer; exact specs vary by vendor.
For precise details (on resistance, leakage, supply voltage range, switching time, and package), consult the specific vendor’s datasheet for the DG409DY revision you have.

Pinout

Pin count: 16 pins (16-pin package, e.g., DIP-16/SO-16).
Function: DG409DY is a dual 4:1 analog multiplexer. It provides two independent 4:1 analog switch/multiplexer sections, each selecting one of four analog inputs to a common output under control of two select lines per section.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A global American semiconductor company that designs, manufactures, and markets analog, mixed-signal, and digital signal processing integrated circuits.

Application

DG409DY is a CMOS analog switch/multiplexer. Common application areas include:
- Analog signal routing and channel multiplexing in data acquisition, test and measurement equipment
- Front-end signal conditioning for A/D/D/A converters
- Audio/video switching and routing in consumer and professional gear
- Sensor signal multiplexing for medical, automotive, and industrial applications
- Programmable signal paths and gain selection in instrumentation
- Low-leakage switching in sample-and-hold circuits
- Compact, power-efficient routing for battery-powered devices

Package

The DG409DY comes in an 8-pin package, typically an SOIC-8 (small-outline). Verify the exact variant in the datasheet.
