MAX4622CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4622CSE+T is a precision, dual, high-speed analog switch in a 16-pin Narrow SO package. It features two single-pole/double-throw (SPDT) poles with two normally closed and two normally open contacts. The device guarantees a low on-resistance of 5Ω maximum, matched to within 0.5Ω between channels, remaining flat 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, off-leakage current less than 5nA at +85°C, and charge injection of 475pC typical.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Ensure the ordering suffix matches the required temperature grade and packaging format. Confirm that the pinout corresponds to the 16-pin Narrow SOIC package. Cross-reference the part number with authorized distributors to ensure compliance with RoHS standards and availability status.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPDT switch with break-before-make timing is required. It serves as a pin-compatible replacement for DG403 devices. Consider the 5Ω on-resistance and 36V single-supply limit for signal path requirements. Verify that the logic input compatibility meets the control interface needs of the target application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4621/MAX4622/MAX4623 family of precision analog switches. The MAX4622 specifically provides the SPDT configuration, whereas the MAX4621 offers SPST normally open poles and the MAX4623 provides DPST normally open poles. All members share identical pinouts and core performance characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4622CSE+T is a pin-compatible replacement for the DG403. Designers should verify that the new component's electrical parameters meet the original system requirements before substitution.
