MAX901BCSE+T

Overview

The MAX901BCSE+T is a quad high-speed, low-power voltage comparator in a 16-pin SOIC package. It operates from a single +5V to +10V analog supply or split ±2.5V to ±5V supplies. Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 4mV maximum input offset voltage, and 10µA maximum input bias current. The device features TTL-compatible push-pull outputs and consumes approximately 18mW per comparator.

Feature Summary

• Features four independent comparators with fast response times suitable for high-speed data discrimination.
• Outputs are TTL-logic compatible with active internal pull-ups, eliminating the need for external termination resistors.
• Analog inputs include the negative supply rail, enabling ground sensing when powered by a single supply.
• Supports separate analog and digital power supplies to isolate noisy digital environments from sensitive analog signals.

Applications

• High-speed A/D converters
• Line receivers
• Voltage-to-frequency (V/F) converters
• Threshold detectors

Procurement Notes

Verify that the specific ordering suffix matches the required temperature range and packaging format. Confirm RoHS compliance status as indicated in official documentation. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any specific handling requirements related to moisture sensitivity levels before assembly.

Selection Notes

Select this part when four comparators are needed without latch functionality. The MAX901 lacks the latch inputs found on the MAX900, MAX902, and MAX903 variants. Choose this model if the application requires standard continuous comparison rather than sampled or held output states. Verify that the 8ns propagation delay meets the system timing requirements.

Part Context

The MAX901 is part of the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices / Maxim Integrated. While sharing similar performance characteristics with other family members, it is distinct in its lack of latch inputs. It serves as a general-purpose solution for applications requiring multiple independent comparisons.

Replacement Considerations

For newer designs requiring pin-for-pin compatibility with half the power dissipation, consider the MAX9201, MAX9202, or MAX9203 series. These devices offer equivalent speed but improved efficiency. Verify that the absence of latch inputs in the replacement does not conflict with existing circuit logic.
