DG612EEY-T1-GE4

Overview

The DG612EEY-T1-GE4 is a monolithic quad single-pole single-throw (SPST) analog switch from Vishay Siliconix, featuring four independently selectable normally open switches. It operates on a 3 V to 16 V single supply or ± 3 V to ± 8 V dual supplies. Key electrical parameters include a typical drain-source on-resistance of 72 Ω, low charge injection of 1.4 pC, and an excellent 3 dB bandwidth of 1 GHz. The device supports rail-to-rail analog signal handling with very low switch capacitance of 3 pF. It is housed in a 16-lead narrow SOIC package and functions reliably across an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Combines CMOS and DMOS technologies for high-speed switching with low power consumption
• Provides rail-to-rail analog signal handling capability
• Features extremely low charge injection and leakage current
• Supports both single and split supply operation

Applications

• Precision instrumentation
• Medical instrumentation
• Automated test equipment
• High-end data acquisition systems
• Sample and hold applications

Procurement Notes

Verify the specific ordering suffix EEY corresponds to the 16-lead narrow SOIC package configuration required for your design. Confirm that the GE4 suffix indicates RoHS compliance and halogen-free status as per Vishay standards. Ensure the component meets the required thermal management specifications for the intended operating environment before finalizing procurement.

Selection Notes

Select this part when a normally open SPST configuration is required alongside high bandwidth and low distortion. Compare the 72 Ω on-resistance against circuit requirements at the target supply voltage. Verify logic compatibility with the 2.5 V CMOS/TTL inputs under the specific single or dual supply conditions planned for the application.

Part Context

This component belongs to the DG611E, DG612E, and DG613E family, which offers improved performance over the industry standard DG611 series. While the DG611E features normally closed switches, the DG612E variant specifically provides all normally open switches. The DG613E offers a complementary mix of two normally open and two normally closed switches within the same package footprint.

FAQ

What is the logic state for turning the DG612E switches ON?

For the DG612E, a logic high input turns the switches ON, while a logic low input turns them OFF.

Does the DG612E support bidirectional signals?

Yes, the switches conduct equally well in both directions and offer rail-to-rail analog signal handling.

What is the maximum analog signal range for the DG612E?

The analog signal range extends from V- to V+, allowing for full rail-to-rail operation within the supply limits.
