MAX4622EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4622EPE is a precision, dual, high-speed analog switch in a 16-pin Plastic DIP package. It features two single-pole/double-throw (SPDT) switches with two normally closed and two normally open poles. 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 <250ns, turn-off time <200ns, off-leakage current <5nA at +85°C, and charge injection of 45pC typical.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EPE indicates the -40°C to +85°C industrial temperature range and 16-pin PDIP package. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for RoHS compliance status as manufacturing processes may evolve. Validate pinout compatibility if replacing legacy components like the DG405.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4622EPE when dual SPDT switching with normally closed and normally open poles is required. Ensure the application benefits from the guaranteed break-before-make timing to prevent short circuits during state transitions. Verify that the 5Ω on-resistance meets the signal integrity requirements compared to higher resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4622EPE belongs to the MAX4621/MAX4622/MAX4623 family of dual, 5Ω analog switches. It serves as a pin-compatible replacement for the DG405, offering improved performance characteristics such as lower leakage and faster switching speeds while maintaining similar form factors for direct board upgrades.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4622EPE is a pin-compatible replacement for the DG405. Verify that the legacy component's specifications align with the MAX4622's electrical limits before substitution.
