MAX394CAP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394CAP+ is a precision, low-voltage, quad single-pole/double-throw (SPDT) analog switch in a 20-pin SSOP package. It operates with bipolar supplies from ±2.7V to ±8V or a single supply of +2.7V to +15V. The device features an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the analog signal range with a maximum variation of 4Ω. It provides break-before-make switching with a typical delay of 10ns, turn-off times under 75ns, and turn-on times under 130ns. Quiescent current is less than 1μA, making it suitable for portable applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CAP+ indicates the commercial temperature range and SSOP packaging. Confirm RoHS compliance status through official documentation as ordering suffixes may affect environmental certifications. Ensure the component matches the exact pinout and electrical specifications required for the target circuit design before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPDT switch with low voltage operation is required. Verify that the supply voltage range aligns with the system's power rails. Consider the thermal performance and derating requirements if operating near the upper limits of the specified temperature range. Ensure logic input levels are compatible with the driving circuitry across the full operating voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX394CAP+ belongs to the MAX394 family of low-voltage analog switches manufactured by Analog Devices/Maxim Integrated. It serves as a direct replacement for the MAX333 and MAX333A series. The part is designed for applications requiring multiple independent analog signal paths with minimal signal distortion and low power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX394CAP+ is pin-compatible with the MAX333 and MAX333A. When substituting these parts, verify that the new component meets the original design's voltage and current requirements. Check for any differences in switching speed or leakage characteristics that might impact high-frequency performance.
