MAX932CPA

Comparators Overview

The MAX932CPA+ is a dual micropower, low-voltage analog comparator housed in an 8-pin Plastic DIP package. It operates from a single +2.5V to +11V supply or ±1.25V to ±5.5V dual supplies. The device features an internal 1.182V ±2% bandgap voltage reference and adjustable hysteresis via the HYST pin. It provides TTL/CMOS-compatible outputs capable of sourcing up to 40mA continuously. Key electrical parameters include a maximum propagation delay of 12µs at 10mV overdrive, a maximum input offset voltage of ±10mV, and a typical quiescent supply current of 6µA.

Comparators Feature Summary

• Dual comparators with integrated 1.182V ±2% bandgap reference
• Adjustable hysteresis using the dedicated HYST pin and two resistors
• TTL- and CMOS-compatible push-pull output stage
• High continuous source current capability of 40mA

Comparators Applications

• Battery-Powered Systems
• Threshold Detectors
• Window Comparators
• Oscillator Circuits
• Alarm Circuits

Comparators Procurement Notes

Verify the specific suffix CPA+ corresponds to the commercial temperature range (0°C to +70°C) and 8-pin Plastic DIP package. Confirm that the ordering information matches the manufacturer's current datasheet revision, as component specifications and availability may change. Ensure compatibility with the required supply voltage range and load conditions before finalizing procurement.

Comparators Selection Notes

Select this component for applications requiring low power consumption alongside high output drive capability. The dual configuration allows for complex logic functions like window detection within a single package. Consider the internal reference accuracy and the need for external hysteresis programming when designing threshold circuits. Verify that the input common-mode range meets the signal requirements relative to the negative supply rail.

Comparators Part Context

The MAX932CPA+ belongs to the MAX931-MAX934 family of ultra-low-power comparators manufactured by Analog Devices / Maxim Integrated. This family is designed for space-saving and energy-efficient applications. The MAX932 specifically offers two comparators per package, distinguishing it from the single-channel MAX931 and the quad-channel MAX934.

Comparators Replacement Considerations

The TSM932 is documented as an electrically and form-factor identical alternate source. For higher precision requirements, the MAX922 series offers a 1% accurate reference, though it is not pin-compatible with the MAX932.
