MAX4722EUA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4722EUA is a dual single-pole single-throw normally-closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8V to 5.5V and features a maximum on-resistance of 4.5 ohms with a channel-to-channel matching of 100 milliohms. The device provides a -3dB bandwidth of 300MHz, charge injection of 5pC, and off-state leakage current of 500pA maximum. Switching times are specified at 80ns for turn-on and 40ns for turn-off. It is housed in an 8-uMAX-EP package and supports an operating temperature range of -40°C to +85°C.

• Smart battery pack management circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EUA' against the official Maxim Integrated part numbering system to confirm the package type and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors as availability may vary. Ensure the component matches the required thermal and electrical ratings for the target application environment before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual normally-closed analog switch is required within a low-voltage single-supply system. The 4.5 ohm on-resistance and 300MHz bandwidth make it suitable for general-purpose signal switching. Compare against the MAX4721 if a normally-open configuration is needed instead. Verify that the 8-uMAX-EP package dimensions fit the available PCB space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4722 belongs to the MAX472x family of low-voltage analog switches designed for portable electronics. It complements the MAX4721 (normally-open) and MAX4723 variants within the same UCSP/8-uMAX footprint family. This series addresses the need for small form-factor signal routing in battery-powered devices where power efficiency and board space are critical design parameters.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4721EUA serves as a functional substitute if a normally-open switch topology is acceptable. Verify pin compatibility and electrical parameter differences between the NC and NO variants before implementation.
