DG405CY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405CY+ is a dual, high-speed analog switch featuring two double-pole/single-throw (DPST) channels. It operates from single +10V to +30V or bipolar ±4.5V to ±20V supplies. The device guarantees low on-resistance matching between switches (2 Ω max) and on-resistance flatness over the signal range (3 Ω max). Typical on-resistance is 20 Ω, with a maximum of 45 Ω. Switching times are 150 ns for turn-on and 100 ns for turn-off. Charge injection is limited to 15 pC max, and off leakage current is less than 5 nA at +85°C. Power consumption is 35 µW max. It is housed in a 16-pin Narrow SO package and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CY+' against official Analog Devices documentation to confirm the package type and RoHS compliance status. Ensure the component meets the required operating temperature range of 0°C to +70°C for your application environment. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent analog switching is required with tight on-resistance matching specifications. It is suitable for applications demanding low power consumption and fast switching speeds. Consider the bipolar supply capability if negative voltage rails are available. Verify that the 45 Ω maximum on-resistance meets the signal integrity requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG405 is part of the Maxim Integrated DG401/DG403/DG405 family of improved dual high-speed analog switches. This series features a redesigned silicon-gate process offering enhanced performance over previous generations. The DG405 specifically provides two DPST switches, distinguishing it from the SPST DG401 and SPDT DG403 variants within the same product line.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance match between channels?

The drain-source on-resistance match between channels is guaranteed to be 2 Ω max.

How does the DG405 handle overvoltage conditions?

Signals on S, D, or IN exceeding V+ or V- are clamped by internal diodes. External blocking diodes can be added for overvoltage protection if proper power-supply sequencing is not possible.

What is the typical charge injection value?

The charge injection is typically 10 pC and guaranteed to be a maximum of 15 pC.
