MAX4525CUB+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4525CUB+ is a low-voltage, single-supply CMOS analog switch configured as a double-pole/double-throw (DPDT) device. It operates from a +2V to +12V supply and handles Rail-to-Rail analog signals. The on-resistance is 200 Ω at +5V and 500 Ω at +3V. Each switch features an inhibit input to open all signal paths simultaneously. Off-leakage current is 2nA at +25°C and 20nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility with a +5V supply. The device is housed in a 10-pin µMAX package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUB' against official documentation to confirm the commercial temperature range of 0°C to +70°C and the 10-pin µMAX package configuration. Ensure that the ordering information matches the exact part number variant required for your design specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a DPDT switch topology is required within a compact footprint. Consider the 200 Ω on-resistance at +5V and the 2nA off-leakage current for applications demanding low power consumption and minimal signal distortion in single-supply environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4524/MAX4525 family of low-voltage analog switches manufactured by Maxim Integrated. While the MAX4524 functions as a 4-channel multiplexer, the MAX4525 provides a dual DPDT configuration. Both share identical electrical characteristics and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the MAX4525EUB (-40°C to +85°C), MAX4525ETB (TDFN-EP package), and MAX4525C/D (dice). Verify pinout and thermal performance compatibility before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the function of the INH pin?

The INH pin serves as an inhibit input. Connecting it to a logic-level high turns all switches off simultaneously, opening all signal paths.

How does the on-resistance vary with supply voltage?

The on-resistance is specified as 200 Ω with a +5V supply and increases to 500 Ω with a +3V supply.

Is the MAX4525CUB+ compatible with standard TTL logic levels?

Yes, the digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.
