DG1209ETE+T

Overview

The DG1209ETE+T is a dual 4-channel analog multiplexer switch in a 16-lead TQFN package. It operates with ±5V to ±20V bipolar or +10V to +20V single supplies, drawing 40µA quiescent current. On-resistance is typically 100Ω (max 160Ω at ±15V) and off-leakage is ≤1nA at +85°C. Charge injection is 0.5pC typical. Switching times are 200ns turn-on and 300ns turn-off at ±15V. The device supports rail-to-rail operation and features GPIO-compatible logic inputs.

Feature Summary

Dual 4-channel architecture with low leakage and charge injection for distortion-free measurement
Wide supply range supporting both bipolar and single-supply configurations
GPIO-compatible control inputs with dedicated enable/disable functionality

Applications

Automatic test equipment systems
Data acquisition systems
Sample-and-hold systems
Communication systems
Audio and video routing

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the tape-and-reel packaging format associated with the 'T' designation. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the selected component matches the required temperature range and package dimensions for your design constraints.

Selection Notes

Select this part when a dual 4-channel configuration is required instead of an 8-channel single multiplexer. Verify that the maximum on-resistance and leakage current specifications meet the signal integrity requirements of the application. Consider the thermal resistance characteristics of the TQFN package during PCB layout planning.

Part Context

This component belongs to the DG1208/DG1209 family of low-leakage analog switches manufactured by Analog Devices/Maxim Integrated. The DG1209 variant specifically provides two independent 4-channel multiplexers within a single integrated circuit, offering a compact solution for differential signal routing applications.

FAQ

How does the DG1209 differ from the DG1208?

The DG1209 is a dual 4-channel multiplexer controlled by two address inputs (A1, A0), whereas the DG1208 is a single 8-channel multiplexer requiring three address inputs (A2, A1, A0).

What is the function of the EN pin?

The EN (Enable) input controls the state of all switches. Driving EN high enables the device to conduct signals based on address inputs, while driving it low disables all channels.
