MAX4501ESA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4501ESA is a single-pole/single-throw (SPST), low-voltage, single-supply CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a normally open configuration and operates continuously with a single supply voltage ranging from +2V to +12V. The device handles Rail-to-Rail analog signals and provides TTL/CMOS logic compatibility at +5V supplies. Key electrical parameters include an on-resistance of 250Ω at +5V, off-leakage current of 1nA at +25°C, and switching speeds of 75ns turn-on and 50ns turn-off. It is housed in an 8-pin SO package and supports an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade. The 'ESA' designation indicates an 8-pin Small Outline package with an extended operating temperature range of -40°C to +85°C. Ensure that the procurement documentation matches these specifications to avoid discrepancies in thermal performance or physical footprint during integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage single-supply operation and Rail-to-Rail signal handling. Consider the 250Ω on-resistance and 1nA off-leakage characteristics when designing precision signal paths. Verify that the control logic levels align with the specified TTL/CMOS thresholds for the intended supply voltage to ensure reliable switching performance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4501/MAX4502 family of low-voltage SPST CMOS analog switches. The MAX4501 variant specifically offers a normally open configuration, whereas the MAX4502 provides a normally closed state. Both share identical electrical characteristics and are designed for portable and battery-powered applications requiring efficient signal routing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4502ESA serves as a functional alternative within the same series, differing only in its normally closed switch configuration. Other packages such as SOT23-5 or Plastic DIP may be considered if form factor changes are acceptable.
