DG1206EUI+

Overview

The DG1206EUI+ is a single 16-channel analog multiplexer switch manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 28-lead TSSOP package. It operates with supply voltages ranging from ±5V to ±20V (bipolar) or +10V to +20V (single). Key electrical parameters include a typical on-resistance of 100Ω and a maximum of 160Ω at ±15V supplies. Leakage current is specified at a maximum of 2nA for the DG1206 variant. The device features a -3dB bandwidth of 150MHz, turn-on/turn-off times between 200ns and 600ns depending on supply voltage, and an operating temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low capacitance and charge injection characteristics minimize signal distortion and glitching during switching operations.
• Rail-to-rail operation capability allows full signal swing across the entire supply voltage range.
• GPIO-compatible control inputs simplify interface logic requirements without additional level shifting.

Applications

• Automatic Test Equipment Systems
• Data Acquisition Systems
• Sample-and-Hold Systems

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Ensure that the ordering information matches the required channel configuration and thermal specifications for the intended application environment before finalizing procurement.

Selection Notes

Select this component when designing systems requiring low leakage and high isolation for precision analog signal routing. Consider the 28-TSSOP package constraints for PCB layout and verify that the supply voltage range aligns with the system's power architecture to ensure optimal on-resistance performance.

Part Context

This component belongs to the DG1206/DG1207 family of low-leakage analog multiplexers. The DG1206 variant provides a single 16-channel configuration, whereas the DG1207 offers a dual 8-channel setup. Both share similar electrical characteristics and are designed for high-performance data acquisition and test applications.

Replacement Considerations

Direct functional substitutes within the same family include the DG1207EUI+ for dual-channel applications. Verify pin compatibility and electrical specifications against the original datasheet before implementing any cross-model replacements.

FAQ

How does the enable input function?

Driving the EN input high enables the multiplexer channels according to the selection inputs. Driving EN low disables all switches, turning them off regardless of the address state.

What is the difference between DG1206 and DG1207?

The DG1206 is a single 16-channel multiplexer controlled by four address inputs (A3-A0). The DG1207 is a dual 8-channel multiplexer controlled by three address inputs (A2-A0), offering differential switching capabilities.

What is the typical on-resistance value?

The typical on-resistance is 100Ω when measured with ±15V bipolar supplies. The maximum on-resistance is specified as 160Ω under the same conditions.
