MAX4503EUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4503EUK-T is a low-voltage, dual-supply, single-pole/single-throw (SPST) CMOS analog switch housed in a SOT23-5 package. It operates with dual supplies between ±1V and ±6V, handling rail-to-rail analog signals. The device features an off-leakage current of 1nA at +25°C and 10nA at +85°C. On-resistance is guaranteed at 250Ω with ±5V supplies. Switching speeds include a turn-on time of 150ns and a turn-off time of 100ns. Charge injection is limited to 10pC maximum. The digital input is CMOS-logic compatible without requiring a ground pin.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'E' designation corresponds to the -40°C to +85°C industrial temperature range. Ensure the component matches the SPST NO configuration for the MAX4503 variant. Cross-reference the manufacturer's official ordering information to validate availability and lead times before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage dual-supply operation and rail-to-rail signal handling. The absence of a ground pin simplifies layout in compact designs. Verify that the logic supply voltage aligns with the CMOS compatibility requirements. Consider the 250Ω on-resistance limit for signal integrity in high-impedance circuits. Evaluate thermal performance within the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4503EUK-T belongs to the MAX4503/MAX4504 family of low-voltage, dual-supply, SPST CMOS analog switches. The MAX4503 variant is normally open, while the MAX4504 is normally closed. Both share identical electrical characteristics and pin configurations. The EUK suffix denotes the SOT23-5 package with an extended temperature range. This family is designed for portable and battery-powered applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4501 and MAX4502 are pin-for-pin equivalents designed for single-supply operation. Verify supply voltage requirements before substitution. Ensure the replacement part supports the necessary analog signal range and leakage specifications. Check package compatibility if physical footprint constraints exist.
