MAX385ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX385ESE+T is a precision, low-voltage analog switch featuring four double-pole single-throw (DPST) channels in a 16-pin narrow SOIC package. It operates with a single positive supply from +3V to +15V or split supplies of ±3V to ±8V. The device provides an on-resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the specified analog signal range with a maximum variation of 4Ω. Leakage current is less than 250pA at +25°C and less than 2.5nA at +85°C. Switching performance includes a turn-on time of less than 175ns and a turn-off time of less than 100ns. Charge injection is guaranteed below 5pC, and power consumption remains under 10µW.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Supports single-supply (+3V to +15V) and bipolar-supply (±3V to ±8V) operation while maintaining CMOS-logic input compatibility.
• Features extremely low charge injection (<5pC) and low power consumption (<10µW) for high system accuracy.
• Provides rail-to-rail analog signal handling capability across the full supply voltage range.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix '+T' corresponds to tape-and-reel packaging as indicated by standard Maxim Integrated conventions, though specific reel quantities are not detailed in the provided datasheet. Confirm the 'E' temperature grade (-40°C to +85°C) matches the application requirements. Ensure the narrow SOIC package dimensions align with the PCB footprint design. Cross-reference the RoHS compliance status if required by local regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple DPST switching functions are required in a compact surface-mount form factor. The guaranteed on-resistance matching of less than 2Ω makes it suitable for applications requiring precise signal routing without significant channel-to-channel variation. Consider the low leakage and fast switching speeds for high-frequency or sensitive analog signal paths where minimal distortion is critical.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX385 is part of the MAX381/MAX383/MAX385 family of precision, low-voltage analog switches fabricated using Maxim’s low-voltage silicon-gate process. This family shares common electrical characteristics such as low on-resistance and low leakage, differing primarily in the number of poles and throw configurations. The MAX385 specifically offers four double-pole single-throw channels, providing higher integration density compared to the single-pole variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin-compatibility with DG401/DG403/DG405 devices. Verify that any substitute maintains the same 16-pin narrow SOIC package and electrical specifications, particularly on-resistance and leakage currents, to ensure direct interchangeability without circuit redesign.
