DG1207EUI+T

Overview

The DG1207EUI+T is a dual 8-channel analog multiplexer switch in a 28-lead TSSOP package. It features low leakage and low charge injection for high-fidelity signal routing. The device operates with ±5V to ±20V bipolar supplies or +10V to +20V single supply. Key electrical parameters include a typical on-resistance of 100Ω (max 160Ω at ±15V), maximum off-leakage current of 1nA, and typical charge injection of 0.5pC. Dynamic characteristics specify turn-on/turn-off times up to 600ns/500ns under single supply conditions, with a -3dB bandwidth of 200MHz.

Feature Summary

Dual 8-channel architecture supporting differential signal paths
Ultra-low capacitance and minimal charge injection for distortion-free measurement
GPIO-compatible control inputs with dedicated enable/disable functionality
Rail-to-rail operation across wide supply voltage ranges

Applications

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

Procurement Notes

Verify the specific suffix 'T' against official documentation to confirm tape-and-reel packaging status, as standard listings may indicate tube packaging. Ensure the component matches the exact Analog Devices part number to avoid confusion with non-RoHS variants or different package types like TQFN.

Selection Notes

Select this component when designing dual-channel differential signal paths requiring low leakage. Verify that the 28-TSSOP package fits the board space constraints compared to the 32-TQFN option. Confirm that the required on-resistance flatness and switching speed meet the system's dynamic performance specifications.

Part Context

This part belongs to the DG1206/DG1207 family of low-leakage analog switches. While the DG1206 provides a single 16-channel configuration, the DG1207 offers a dual 8-channel topology. Both share identical electrical characteristics regarding leakage, resistance, and bandwidth, differing primarily in channel count and address input logic.

Replacement Considerations

Direct replacement options within the same series include DG1207ETJ+ for the 32-TQFN package variant. Cross-family replacements require matching the dual 8-channel configuration and verifying pin compatibility if form-factor changes are acceptable.

FAQ

How does the DG1207 differ from the DG1206?

The DG1207 is a dual 8-channel multiplexer using three selection inputs (A2, A1, A0), whereas the DG1206 is a single 16-channel multiplexer using four selection inputs (A3, A2, A1, A0).
