Overview
The MAX902ESD+ is a high-speed, low-power dual voltage comparator from the MAX900–MAX903 series. It features differential analog inputs and TTL-logic outputs with active internal pull-ups. The device operates on separate analog and digital supplies or a single combined supply. Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 18mW power consumption per comparator at +5V, and an input common-mode range that includes the negative rail for ground sensing.
Feature Summary
- Features independent TTL-compatible latch inputs to hold output states when driven low.
- Supports flexible analog supply voltages ranging from +5V to +10V or ±5V.
- Provides separate analog and digital power supply pins to isolate signals in mixed-signal applications.
Applications
- High-speed A/D converters
- Line receivers
- Voltage-to-frequency (V/F) converters
- Data-discrimination circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for Not Recommended for New Designs (NRND) status before integration into new hardware designs. Ensure proper handling of static-sensitive components during installation.
Selection Notes
Select this part for applications requiring fast response times and latch functionality. Consider the MAX920x series for newer designs offering pin-for-pin compatibility with reduced power dissipation. Verify supply voltage requirements match the specific analog and digital rails available in the target system architecture.
Part Context
This component belongs to the MAX900–MAX903 family of high-speed comparators manufactured by Maxim Integrated, now part of Analog Devices Inc. The MAX902 specifically provides two comparator channels in a 14-pin package. The datasheet indicates it was manufactured using a process no longer available for new designs.
Replacement Considerations
The MAX9202 is identified as a newer, pin-for-pin compatible replacement offering similar speed with lower power dissipation. Users should consult the MAX9202 data sheet for updated specifications and availability.
