DG445DVZ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG445DVZ is a quad single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 5 V to 34 V for single supplies, or ±5 V to ±22 V for dual supplies. The device features a maximum on-resistance of 85 Ohms and supports a continuous DC switch current of 30 mA. Switching times are specified with a maximum turn-on time of 250 ns and a maximum turn-off time of 210 ns. It is housed in a 16-TSSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four independent SPST switches into a single compact integrated circuit.
• Supports both single and dual power supply configurations for flexible system design.
• Provides low charge injection characteristics suitable for precision signal routing.

Analog Switches, Multiplexers, Demultiplexers Applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements before finalizing procurement orders. Ensure the supplier provides valid traceability documentation for the manufacturing lot.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance. Compare against the DG442 series if lower power consumption is critical, as that variant utilizes CMOS technology. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG44x family of high-performance analog switches. It shares functional similarities with other devices in the series but differs in specific electrical parameters such as on-resistance and switching speed. The DVZ suffix specifically denotes the 16-pin TSSOP surface-mount package format.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG411BRUZ is listed as a similar replacement option. Verify pin compatibility and electrical parameter alignment before substituting. Ensure the alternative device meets the same voltage and temperature specifications.
