DG202CJ

Analog Switches, Multiplexers, Demultiplexers Overview

The Intersil DG202CJ is a quad CMOS analog switch featuring four independent single-pole single-throw (SPST) normally-open channels. It operates on dual supplies ranging from ±4.5V to ±18V or a single supply up to 36V. The device specifies a maximum on-resistance of 200Ω and low charge injection of 20pC. Switching times are rated at 600ns for turn-on and 450ns for turn-off. It utilizes a 16-pin PDIP package with through-hole mounting.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Quad SPST configuration providing four independent signal paths
• Low on-resistance for minimal signal attenuation
• Low charge injection to preserve signal integrity during switching
• High off-isolation to prevent crosstalk between channels

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Multiplexing audio and video signals
• Programmable gain amplifier circuits
• Calibration and test equipment signal paths

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation, as Analog Devices Inc. acquired Maxim Integrated, which previously held this product line. Confirm the specific suffix 'CJ' corresponds to the required commercial temperature range and 16-PDIP package. Ensure RoHS compliance status matches project requirements, as older stock may differ from current manufacturing runs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple independent analog switches are required in a single package. The 200Ω on-resistance suits applications where moderate impedance is acceptable. Verify that the ±4.5V minimum supply voltage aligns with the system power rails. Consider the 16-pin DIP footprint for prototyping or legacy board designs requiring through-hole assembly.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG202 belongs to the DG200 series of improved quad CMOS analog switches. It shares functional similarities with the DG201 and DG202 but differs in specific electrical parameters like on-resistance and leakage. This family is designed for general-purpose analog switching tasks requiring low distortion and high reliability.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202BAK-E3 by Vishay/Siliconix is an alternative quad CMOS analog switch. Verify pin compatibility and electrical parameter alignment before substitution. Note that some variants may have different temperature ranges or packaging options.
