MAX4518CSD

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4518CSD+ is a precision, monolithic CMOS analog multiplexer housed in a 14-pin SO package. It features four independent channels with an on-resistance of less than 100 Ω and a maximum matching tolerance of 4 Ω between channels. The device operates on a single supply ranging from +2.7 V to +15 V or dual supplies from ±2.7 V to ±8 V. Key electrical parameters include a transition time of 250 ns maximum, charge injection under 5 pC, and off-leakage current below 2 nA at +85°C. It provides over 2000 V electrostatic discharge protection and maintains rail-to-rail signal handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official manufacturer documentation to confirm pinout compatibility and electrical specifications before integration. Ensure that the operating voltage limits and thermal dissipation requirements align with the target system design. Cross-reference the specific suffix codes to validate the exact package type and temperature range intended for the application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise channel matching and low leakage are required for analog signal routing. Consider the 14-pin SO package constraints and verify that the single-supply or dual-supply configuration matches the available power rails. Evaluate the switching speed and charge injection characteristics against the signal bandwidth and accuracy requirements of the circuit.
