MAX352ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX352ESE+ is a precision, quad, single-pole single-throw (SPST) analog switch featuring four normally open channels. It operates with a single positive supply from +10V to +30V or split supplies ranging from ±4.5V to ±20V. The device guarantees an on resistance of less than 35Ω, matched within 2Ω between channels and remaining flat over the analog signal range with a maximum variation of 3Ω. Switching performance includes a turn-on time of less than 175ns and a turn-off time of less than 145ns. Leakage current is specified at less than 250pA at +25°C and less than 6nA at +85°C. Charge injection is extremely low at 10pC. The component utilizes a 44V silicon-gate process for rail-to-rail analog signal handling and electrostatic discharge protection exceeding 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure that any alternative part numbers are cross-referenced with the original datasheet to validate pinout and electrical parameter compatibility before integration into designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high precision and low leakage are required for analog signal routing. The wide supply voltage range supports both single and dual supply architectures. Verify that the 35Ω on-resistance meets system requirements for signal integrity and power dissipation limits in the target application environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX351/MAX352/MAX353 family of precision analog switches. While the MAX351 features normally closed contacts and the MAX353 combines both types, the MAX352 specifically provides four normally open channels. All variants share identical fabrication processes and core electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same series include the MAX351ESE+ and MAX353ESE+. These parts share the same package and thermal specifications but differ in switch contact states. Verify functional requirements match the specific NO/NC configuration of the replacement.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX352 handle overvoltage conditions?

Signals on the COM, NO, or NC terminals exceeding the supply rails will be clamped by internal diodes. Designers must limit the forward diode current to the maximum rating of 30mA to prevent damage.

What is the charge injection specification?

The MAX352 offers extremely low charge injection of 10pC, guaranteed by design, which minimizes signal distortion during switching transitions.

Can the device operate with unbalanced supplies?

Yes, the device can be powered from unbalanced supplies, such as +24V and -5V, provided the difference between V+ and V- does not exceed the absolute maximum rating of 44V.
