DG1208ETE+T

Overview

The DG1208ETE+T is a single 8-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 typical quiescent current. On-resistance is typically 100Ω (max 160Ω at ±15V) and off-leakage current is ≤1nA at +85°C. Charge injection is typically 0.5pC. Dynamic performance includes turn-on times of 200ns to 400ns and -3dB bandwidth of 200MHz. The device supports rail-to-rail operation and GPIO-compatible logic inputs.

Feature Summary

Low leakage and low charge injection for distortion-free measurement
Wide supply range supporting both bipolar and single-supply configurations
GPIO-compatible control inputs with dedicated enable 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 package type and RoHS compliance status. The 'E' indicates a TQFN package while 'U' denotes TSSOP. Confirm that the '+T' suffix matches the required reel quantity for surface-mount assembly processes.

Selection Notes

Select this component when low charge injection and high off-isolation are critical for signal integrity. Ensure the application voltage stays within the specified ±20V or +20V limits. Verify that the 16-TQFN thermal resistance characteristics align with the target PCB layout and power dissipation requirements.

Part Context

This part belongs to the DG1208/DG1209 family of low-leakage analog multiplexers manufactured by Analog Devices/Maxim Integrated. The DG1208 variant provides a single 8-channel configuration, whereas the DG1209 offers dual 4-channel switching. Both share similar electrical characteristics and package options.
