MAX900ACPP

Overview

The MAX900ACPP is a low-power voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It features four general-purpose channels with latch functionality in a 20-pin DIP package. The device operates on a single supply voltage ranging from 5 V to 10 V, consuming 15 mA of operating current. Key electrical specifications include an 8 ns response time, 4 mV input offset voltage, and 10 uA input bias current. It provides high common-mode rejection of 82.5 dB and power supply rejection of 80 dB, with a maximum power dissipation of 500 mW.

Feature Summary

• Integrates four independent general-purpose comparators within a single integrated circuit.
• Includes built-in latch functionality for holding output states after triggering events.
• Designed for low-power operation suitable for battery-powered or energy-efficient applications.
• Features push-pull outputs compatible with TTL logic levels.

Applications

• General-purpose voltage monitoring circuits
• Threshold detection systems
• Logic interface adapters
• Over-voltage protection circuits

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm the specific suffix 'ACPP' denotes the commercial temperature range and 20-DIP packaging variant. Check for obsolescence status as older Maxim products may have limited availability or be subject to last-time-buy notices. Ensure compatibility with existing PCB footprints for 20-pin DIP packages during procurement planning.

Selection Notes

Select this component when multiple comparator channels are required in a compact through-hole package. It is suitable for designs needing latch capability without external components. Consider the 5 V to 10 V supply range and 15 mA current consumption against system power budgets. Verify that the 8 ns propagation delay meets the timing requirements of the target application compared to faster alternatives.

Part Context

The MAX900 series represents a family of low-power analog comparators from Maxim Integrated. The ACPP variant specifically refers to the commercial grade version housed in a 20-pin dual in-line package. This part belongs to the broader linear IC category focused on signal conditioning and comparison tasks. It shares architectural similarities with other MAX90x devices but offers distinct channel counts and package options.

Replacement Considerations

Direct pin-to-pin replacements may include other MAX900 variants with different suffixes indicating package or temperature changes. Cross-reference with MAX900BCWP for surface mount equivalents if board space allows. Verify functional equivalence regarding latch behavior and output drive capabilities before substitution.

FAQ

Does the MAX900ACPP include internal hysteresis?

No, the datasheet specifies it as a general-purpose comparator with latch functionality but does not list internal hysteresis as a standard feature.

What is the maximum power dissipation rating?

The maximum power dissipation is rated at 500 mW (1/2 W).
