MAX4503CSA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4503CSA is a low-voltage, dual-supply, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally open configuration and operates with dual supplies ranging from ±1V to ±6V. The device handles rail-to-rail analog signals with an on-resistance of 250Ω at ±5V supplies. Key electrical parameters include off-leakage current of 1nA at +25°C and turn-on/turn-off times of 150ns and 100ns respectively. It utilizes a unique logic input architecture for CMOS compatibility without a ground pin and is housed in an 8-pin SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the 'S' suffix corresponds to the 8-pin Small Outline package. Ensure the ordering code matches the exact manufacturer designation provided in official documentation to avoid discrepancies in specifications or packaging.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring dual-supply SPST switching with low leakage. Consider the MAX4501/MAX4502 if single-supply operation is required instead. Evaluate the on-resistance variations across different supply voltages and temperatures. Verify that the logic levels are compatible with the positive supply voltage V+.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4503 belongs to the MAX4503/MAX4504 family of low-voltage CMOS analog switches. The MAX4503 variant is specifically designed as a Normally Open switch, whereas the MAX4504 serves as the Normally Closed counterpart. Both share identical pinouts and electrical characteristics except for their default states.
