Overview
The DG1208EUE+T is a low-leakage, single 8-channel analog multiplexer switch in a 16-lead TSSOP package. It operates with ±5V to ±20V bipolar or +10V to +20V single supplies. Key electrical parameters include a typical on-resistance of 100Ω (max 160Ω at ±15V), off-leakage current ≤1nA at +85°C, and charge injection of 0.5pC. Dynamic performance features a -3dB bandwidth of 200MHz, turn-on time of 400ns max, and break-before-make time of 50ns. The device supports rail-to-rail operation and includes an enable input for power management.
Feature Summary
- Low leakage and low charge injection characteristics suitable for precision signal routing
- 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 indicated by the 'T' designation. Ensure compatibility with the required temperature range and voltage specifications before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring low distortion and fast settling times. Verify that the system's logic levels align with the specified VIH and VIL thresholds. Confirm that the thermal dissipation requirements are met within the operating temperature range.
Part Context
This part belongs to the DG1208/DG1209 family of analog multiplexers manufactured by Analog Devices/Maxim Integrated. It shares architectural similarities with the DG1209 but provides a single 8-channel configuration instead of dual 4-channel outputs.

FAQ
What is the function of the EN pin?
The EN pin enables or disables the device. Driving it high enables the multiplexer, while driving it low switches all channels off.
How does the DG1208 select channels?
It uses three selection inputs: A2, A1, and A0. These inputs determine which of the eight normally-open inputs connects to the common output.
What is the maximum off-isolation value?
The off-isolation is typically -80 dB at a switching frequency of 1MHz.
