DG202CSE-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG202CSE-T is a quad single-pole single-throw (SPST) normally-open CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on dual supplies ranging from ±4.5V to ±18V and features a maximum on-resistance of 200 ohms. The device includes four independent channels with a charge injection of 20pC and an off-state leakage current of 5nA. Switching times are specified at 600ns for turn-on and 450ns for turn-off, with a crosstalk rejection of -90dB at 100kHz. It is housed in a 16-SOIC surface-mount package and supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging availability versus tube packaging variants. Ensure the component meets RoHS3 compliance requirements for the intended manufacturing process. Cross-reference the full part number with authorized distributor catalogs to validate current production status and lead time constraints before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring multiple isolated analog paths controlled by digital logic levels. Confirm that the supply voltage range aligns with the system's dual power rails. Evaluate the 200-ohm on-resistance against the application's signal integrity requirements to ensure acceptable voltage drop across the switched signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG202 family of quad SPST analog switches. It shares functional similarities with other members like the DG202CSE+ but differs in packaging format. The series is designed for general-purpose analog signal switching where low distortion and moderate speed are required.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the DG202CSE+ in tube packaging. Verify electrical parameter equivalence, particularly on-resistance and leakage current, before implementing any alternative source or package variant in existing designs.
