MAX4527CPA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4527CPA+ is a CMOS phase-reversal analog switch optimized for low-power applications. It operates from single supplies of +4.5V to +36V or dual supplies of ±4.5V to ±18V. The device features a maximum on-resistance of 175Ω with an on-resistance match of 8Ω maximum. Leakage current is limited to 0.5nA at +25°C and 10nA at +85°C. Charge injection is 10pC maximum, with a charge-injection match of 2pC maximum. Transition time is 250ns maximum. The component supports rail-to-rail analog signal handling and includes 2kV ESD protection per Method 3015.7. It is available in an 8-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The 'CPA' designation indicates an 8-pin Plastic DIP package with a commercial operating temperature range of 0°C to +70°C. Confirm RoHS compliance status as indicated by the '+' suffix in the model name. Ensure the supply voltage requirements align with the specified operational limits before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4527CPA+ when low power consumption is prioritized over high-speed performance, distinguishing it from the MAX4526 variant. Verify that the required operating temperature falls within the 0°C to +70°C commercial range; otherwise, consider the 'E' grade for extended temperatures. Ensure the application utilizes balanced signals suitable for phase reversal, as the device cannot reverse single-ended grounded signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4527 is part of the Maxim Integrated MAX4526/MAX4527 family of phase-reversal analog switches. While the MAX4526 is optimized for high-speed applications, the MAX4527 is designed for lower current consumption. Both share identical analog switch characteristics but differ in their internal logic-level translators and switch drivers. This component serves as a compact solution for implementing chopper amplifiers and balanced modulators in small form factors.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4526 is a direct pin-compatible substitute offering higher speed but increased power consumption. For extended temperature ranges, the MAX4527EPA provides the same functionality in an 8-pin Plastic DIP package with operation from -40°C to +85°C.
