MAX4622CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4622CPE+ is a precision, dual-channel analog switch in a 16-pin Plastic DIP package. It features a single-pole/double-throw (SPDT) configuration with two normally closed and two normally open poles. The device operates from a single positive supply (+4.5V to +36V) or bipolar supplies (±4.5V to ±18V). Key electrical parameters include a maximum on-resistance of 5Ω, guaranteed on-resistance matching within 0.5Ω between channels, and turn-on/turn-off times under 250ns and 200ns respectively. It maintains low leakage currents below 5nA at +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE+' corresponds to the commercial temperature range and plastic DIP package when sourcing. Confirm that the component meets RoHS standards if required by the manufacturing process. Ensure the ordering code matches the exact pinout and functional requirements for the SPDT configuration before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring precise channel matching and low distortion. The SPDT configuration is suitable where signal path inversion or alternate routing is necessary. Consider the ±4.5V to ±18V bipolar supply range for symmetric signal handling. Verify that the 5Ω on-resistance meets the load current requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX462x family of dual, high-speed analog switches manufactured by Analog Devices / Maxim Integrated. It serves as a pin-compatible replacement for legacy parts like the DG403. The CPE+ designation indicates the commercial temperature grade and lead-free packaging compliant with environmental directives.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4622CPE+ is a pin-compatible replacement for the DG403. Designers upgrading from older CMOS switches should verify that the new on-resistance flatness and leakage characteristics meet the system's noise and accuracy specifications.
