MAX4502CPA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4502CPA is a single-pole/single-throw (SPST), low-voltage, single-supply CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally closed (NC) configuration and operates continuously with a single supply between +2V and +12V. The device handles Rail-to-Rail analog signals and offers guaranteed on-resistance of 250Ω at +5V. Key electrical parameters include off-leakage current of 1nA at +25°C and 10nA at +85°C, on-leakage current of 2nA at +25°C, and charge injection of 10pC. Switching speeds are specified as tON = 75ns and tOFF = 50ns. It utilizes TTL/CMOS-logic compatible inputs with thresholds of 0.8V and 2.4V when using a +5V supply. The component is housed in an 8-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix CPA corresponds to the 8-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement. Ensure the application environment remains within the specified absolute maximum ratings to prevent permanent damage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4502CPA when a normally closed state is required upon power-up or logic low input. Compare against the MAX4501 series if a normally open configuration is preferred instead. Consider the SOT23-5 or SC70-5 packages if board space constraints necessitate smaller surface-mount footprints rather than the larger DIP form factor.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4502CPA belongs to the MAX4501/MAX4502 family of low-voltage CMOS analog switches. This series provides single-channel switching solutions designed for portable and battery-powered electronics. The CP designation indicates the commercial temperature grade, distinguishing it from extended industrial or military variants within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4501CPA serves as the primary alternative within the same package and temperature range, differing only in its normally open (NO) configuration compared to the MAX4502's normally closed (NC) state.
