MAX391ESE+TG05

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX391ESE+TG05 is a precision, quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed (NC) switches and operates from a single +3V to +15V supply or dual ±3.0V to ±8V supplies. The device offers low leakage of 100pA maximum and fast switching speeds with turn-on time ≤ 130ns and turn-off time ≤ 75ns. Power consumption is minimal at 1µW. With ±5V supplies, it provides guaranteed 2Ω maximum channel-to-channel matching, 30Ω maximum on-resistance, and 4Ω maximum on-resistance flatness.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix '+TG05' against official manufacturer documentation to confirm tape and reel packaging details and any unique handling requirements. Ensure compatibility with standard SOIC-16 surface mount processes. Confirm RoHS compliance status through current datasheets as manufacturing standards may evolve over time.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when normally closed analog switching is required in space-constrained designs. The narrow SOIC package allows for high-density PCB layouts. Consider the ±5V performance specifications if bipolar signal handling is necessary, noting that single-supply operation characteristics differ slightly regarding on-resistance limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX391/MAX392/MAX393 family of precision analog switches. While the MAX392 offers normally open switches and the MAX393 combines both types, the MAX391 specifically provides four normally closed channels. This configuration is distinct within the series and requires appropriate logic inversion for control signals compared to the other variants.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX391?

The MAX391 contains four normally closed (NC) switches, meaning they are conductive when the logic input is low.

How does the MAX391 handle overvoltage conditions?

Signals exceeding V+ or V- are clamped by internal diodes. For proper protection without exceeding absolute maximum ratings, external blocking diodes can be added if power-supply sequencing cannot be controlled.

What is the typical charge injection value?

The device offers a maximum charge injection of 5pC, which simplifies sample-and-hold applications by reducing signal distortion during switching transitions.
