DG212EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG212EUE+ is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual power supplies ranging from ±4.5V to ±18V and features inverted control inputs compared to the DG201/DG211 series. The device utilizes monolithic low-power CMOS technology, eliminating the need for a separate logic supply voltage (VL). Key electrical parameters include a maximum drain-source on-resistance of 175Ω at ±15V, a continuous current capacity of 20mA per channel, and a maximum power dissipation of 755mW in the TSSOP package. It supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed nonlatching operation when power supplies are disconnected while input signals remain connected
• CMOS and TTL logic compatible without requiring a third logic power supply
• Monolithic low-power design suitable for portable applications
• Break-before-make switching with essentially constant on-resistance over the analog signal range

Analog Switches, Multiplexers, Demultiplexers Applications

• Analog multiplexers
• Programmable gain amplifiers
• Communications systems
• Sample/holds
• Automatic test equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the component matches the specific DG212EUE+ designation, which indicates the extended temperature grade (-40°C to +85°C) and TSSOP-16 packaging. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates before procurement. Ensure the ordering suffix aligns with the required thermal and mechanical specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG212EUE+ when inverted logic control inputs are required, as it differs from the DG202EUE+ only in this aspect. Evaluate the 175Ω maximum on-resistance against circuit requirements, noting that resistance varies with the analog signal level and supply voltage. Consider the ±18V maximum supply range and ensure the external protection diodes are included if fault conditions involving overvoltages are anticipated.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG212EUE+ belongs to the DG202/DG212 family of quad SPST CMOS analog switches. It shares identical pinouts and electrical characteristics with the DG202EUE+, differing solely in the inversion of the logic control inputs. This family is designed to replace older discrete solutions, offering integrated break-before-make timing and latch-up immunity within a compact surface-mount footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202EUE+ serves as a direct functional substitute, provided the system logic accommodates the non-inverted control inputs. Other DG212 variants such as DG212DY or DG212DJ offer alternative packages but must be verified for pin compatibility and thermal performance.
