DG1208EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG1208EUE+ is a single 8-channel analog multiplexer switch in a 16-lead TSSOP package. It 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), off-leakage current ≤1nA, and charge injection ≤0.5pC. Dynamic performance features a -3dB bandwidth of 200MHz, turn-on time up to 400ns, and break-before-make time of 50ns. The device supports GPIO-compatible logic inputs and includes an enable pin for power management.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. The EUE+ designation indicates a lead-free, RoHS-compliant 16-TSSOP package variant. Confirm availability through authorized distributors as production status may vary. Ensure environmental specifications match the required operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG1208EUE+ when a single 8-channel configuration is required rather than the dual 4-channel DG1209. Verify that the control logic requirements align with the three selection inputs (A2, A1, A0). Ensure the application benefits from the low charge injection and high off-isolation provided by this CMOS technology compared to standard analog switches.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG1208/DG1209 family of low-leakage, low-charge-injection analog multiplexers manufactured by Analog Devices / Maxim Integrated. The series is designed for applications requiring fast settling times and minimal signal distortion. The EUE+ suffix specifically identifies the surface-mount TSSOP package option within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG1209EUE+ serves as a functional alternative if a dual 4-channel configuration is acceptable instead of the single 8-channel layout. Both devices share identical pinouts for power and control signals but differ in channel architecture and address decoding logic.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG1208EUE+ handle signal direction?

The common terminal (COM) and normally-open terminals (NO1–NO8) are bidirectional, allowing the analog signal to flow in either direction depending on the circuit configuration.

What is the function of the EN pin?

The Enable (EN) input controls the device state. Driving EN high activates the selected channel, while driving it low disables all switches, effectively turning the multiplexer off.

What is the maximum supply voltage range?

The device supports positive supply voltages (VPOS) from +5V to +20V and negative supply voltages (VNEG) from -20V to -5V, allowing for flexible single or dual supply designs.
