MAX901ACPE+

Overview

The MAX901ACPE+ is a quad high-speed, low-power voltage comparator in a 16-pin Plastic DIP package. It features differential analog inputs and TTL-logic outputs with active internal pull-ups. The device operates from separate analog and digital supplies or a single combined supply ranging from +5V to +10V (or ±5V). Key electrical characteristics include an 8ns typical propagation delay at 5mV overdrive, 2mV maximum input offset voltage, and 6µA maximum input bias current. Power consumption is typically 18mW per comparator at +5V.

Feature Summary

• Features four independent comparators with fast propagation delay for high-speed data discrimination.
• Provides TTL-compatible outputs with active internal pull-ups for direct logic interfacing.
• Supports flexible power supply configurations including separate analog/digital rails or single supply operation.
• Analog input common-mode range extends to the negative rail, enabling ground sensing.

Applications

• High-speed A/D converters
• Fast V/F converters
• Line receivers
• Threshold detectors
• Input trigger circuitry

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm the specific suffix indicates the commercial temperature grade and PDIP packaging. Check for RoHS compliance status as indicated in official documentation. Ensure design-in compatibility with existing board layouts due to pin configuration.

Selection Notes

Select this part when four independent comparators are required without latch functionality. The MAX901 lacks the latch inputs found in the MAX900/MAX902/MAX903 variants. Consider the MAX920x series for newer designs requiring similar speed with lower power dissipation. Verify supply voltage requirements match the +5V to +10V operational range.

Part Context

The MAX901 is part of the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices/Maxim Integrated. Unlike other members of the series, it does not include latch inputs. The datasheet notes that the original manufacturing process is no longer available, and the component is not recommended for new designs.

Replacement Considerations

The MAX9201/MAX9202/MAX9203 are suggested replacements offering pin-for-pin compatibility with half the power dissipation. Industry second-sources may also be available for existing designs.
