Overview
The DG1209EUE+T is a dual 4-channel analog multiplexer switch in a 16-lead TSSOP package. It operates with ±5V to ±20V bipolar supplies or +10V to +20V single supply, drawing 40µA typical quiescent current. On-resistance is typically 100Ω (±15V) or 165Ω (+12V), with off-leakage ≤1nA at +85°C. Switching times are 200–600ns turn-on and 250–500ns turn-off. Bandwidth reaches 250MHz, with charge injection of 0.5pC and off-isolation of -80dB.
Feature Summary
- Dual 4-channel architecture for differential signal routing
- Low leakage and low charge injection for distortion-free measurement
- Wide supply range supporting rail-to-rail operation
- GPIO-compatible control inputs with dedicated enable pin
Applications
- Automatic test equipment systems
- Data acquisition systems
- Sample-and-hold systems
- Communication systems
- Audio and video routing
Procurement Notes
Verify the 'T' suffix indicates tape-and-reel packaging rather than tube. Confirm RoHS compliance status via manufacturer documentation. Ensure the specific lot date code meets project requirements. Check for any regional distribution restrictions before finalizing procurement plans.
Selection Notes
Select this part over DG1208 when a dual 4-channel configuration is required instead of a single 8-channel layout. The device supports both bipolar and single-supply designs. Verify that the 165Ω on-resistance under single-supply conditions meets system impedance requirements.
Part Context
This component belongs to the DG1208/DG1209 family of low-leakage analog multiplexers. It shares identical electrical characteristics with the DG1208 but offers a different channel topology. Both devices utilize CMOS technology and are designed for high-performance switching applications requiring minimal signal distortion.
Replacement Considerations
DG1208EUE+T serves as the functional equivalent within the same series, differing only in channel configuration (single 8:1 vs. dual 4:1). No other direct substitutes are documented in the official datasheet.
