MAX902CPD+

Overview

The MAX902CPD+ is a dual-channel high-speed voltage comparator from the Analog Devices / Maxim Integrated MAX900–MAX903 series. It features TTL-logic outputs with active internal pull-ups and independent latch inputs for holding output states. The device operates on separate analog and digital supplies or a single combined supply, supporting an analog range of +5V to +10V (with VEE grounded) or ±5V. Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 4mA typical operating supply current per channel, and a maximum power dissipation of 500mW. It is housed in a 14-pin PDIP package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Features independent TTL-compatible latch inputs that hold the comparator output state when driven low.
• Provides flexible analog supply operation ranging from +5V to +10V or split ±5V configurations.
• Includes differential analog inputs where the common-mode range extends to the negative supply rail.

Applications

• High-speed A/D converters
• Fast sampling circuits
• Line receivers
• Voltage-to-frequency (V/F) converters

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and temperature rating. Check for availability status as older components may be subject to limited supply or discontinuation notices.

Selection Notes

Select this part for applications requiring fast response times and precise signal discrimination. Ensure the design accommodates the requirement for separate analog and digital power rails if noise isolation is critical. Verify that the input slew rates meet minimum requirements to prevent oscillation during transitions.

Part Context

This component belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices / Maxim Integrated. The MAX902 specifically provides two comparator channels with latch functionality, distinguishing it from the non-latch MAX901 variant.

Replacement Considerations

The datasheet notes the MAX900 was manufactured using a process no longer available and recommends the MAX902/MAX903 for new designs. For newer parts with similar speed but lower power consumption, consult the MAX9201/MAX9202/MAX9203 specifications.
