MAX907CSA+

Overview

The MAX907CSA+ is a dual high-speed, ultra-low-power voltage comparator designed for single +5V supply systems. It features a 40ns propagation delay with 5mV input overdrive and consumes only 3.5mW per comparator. The device operates within a 4.5V to 5.5V positive supply range and supports an input common-mode range extending from 200mV below ground to within 1.5V of the positive rail. It incorporates internal hysteresis for clean switching and provides TTL-compatible outputs without external pullup circuitry.

Feature Summary

• Incorporates internal hysteresis to ensure clean output switching when driven by slow-moving input signals.
• Features TTL-compatible outputs that require no external pullup circuitry.
• Includes built-in input and output short-circuit protection allowing continuous connection to either supply rail.

Applications

• Battery-powered systems
• High-speed A/D converters
• Threshold detectors/discriminators

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Cross-reference the ordering information in the official datasheet to ensure the specific suffix matches the required temperature range and packaging format. Validate RoHS compliance status as indicated in the documentation.

Selection Notes

Select this component for applications requiring high speed combined with low power consumption under a single +5V supply. Ensure the design accommodates the specified input common-mode range and utilizes a low-inductance ground plane. Consider the fixed internal hysteresis characteristics during circuit layout to optimize performance for threshold detection tasks.

Part Context

This part belongs to the MAX907/MAX908/MAX909 family of comparators manufactured by Analog Devices Inc./Maxim Integrated. While the MAX909 offers complementary outputs and a latch, the MAX907 provides a dual-channel configuration in an 8-pin SO package. The series is engineered for precision analog interface applications where micropower operation is critical.

Replacement Considerations

The datasheet states the device was manufactured using a process no longer available and is not recommended for new designs. Consult technical support for Maxim replacement options or industry second-sources suitable for existing users.
