MAX4622CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4622CPE+ is a precision, dual, high-speed analog switch in a 16-pin Plastic DIP package. It features two single-pole/double-throw (SPDT) poles with two normally closed and two normally open contacts. The device guarantees a maximum on-resistance of 5Ω, matched to within 0.5Ω between channels, with flatness remaining constant over the full analog signal range. It operates from a single positive supply (+4.5V to +36V) or bipolar supplies (±4.5V to ±18V). Key electrical parameters include turn-on time under 250ns, turn-off time under 200ns, and off-leakage current less than 5nA at +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as the C-grade variant typically indicates commercial temperature range availability. Confirm the specific suffix aligns with the required operating temperature and packaging format before finalizing orders. Cross-reference the manufacturer's latest documentation to ensure compliance with current RoHS standards and lead times.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when dual SPDT functionality is required alongside low distortion characteristics. Ensure the application voltage does not exceed the specified single or bipolar supply limits. Consider the break-before-make timing if sequential switching is critical to prevent signal overlap in the circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX462x family of precision analog switches, designed as pin-compatible replacements for legacy DG401/DG403/DG405 devices. The MAX4622 specifically addresses applications needing double-pole switching with complementary contact states, offering improved performance over mechanical relays in terms of size and reliability.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4622 serves as a direct pin-compatible drop-in replacement for the DG403. Verify that the substitute maintains the required SPDT configuration and on-resistance specifications to ensure circuit compatibility without redesigning the PCB layout.
