MAX901AESE+T

Overview

The MAX901AESE+T is a high-speed, low-power quad 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, input offset voltage of 2mV (typ), and input bias current of 6µA (typ). Power consumption is 18mW per comparator at +5V. The component supports flexible analog supply voltages ranging from +5V to +10V or ±5V.

Feature Summary

• Features fast propagation delay for high-speed data discrimination applications
• Provides TTL-compatible outputs with active internal pull-ups
• Supports separate analog and digital power supplies for noise isolation
• Analog input common-mode range includes the negative supply rail

Applications

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

Procurement Notes

Verify the specific suffix 'E' indicates the -40°C to +85°C temperature range and 'SE' denotes the SOIC package. Confirm RoHS compliance status through official documentation. Check for availability as the datasheet notes this family may be not recommended for new designs; consult technical support for current production status and potential replacement options.

Selection Notes

Select the MAX901AESE+T when four independent comparators are required without latch functionality. Choose this part over the MAX900/MAX902/MAX903 if latch inputs are unnecessary. Ensure the design accommodates separate analog and digital ground planes to minimize noise coupling in mixed-signal environments. Verify that the input slew rate meets requirements to prevent output oscillation.

Part Context

This component belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices Inc./Maxim Integrated. The MAX901 specifically provides quad channels but lacks the independent TTL-compatible latch inputs found in the MAX900, MAX902, and MAX903 variants. It shares the same pinout and performance characteristics regarding speed and power consumption within the series.

Replacement Considerations

The datasheet recommends the MAX9201/MAX9202/MAX9203 series as newer alternatives offering pin-for-pin compatibility with half the power dissipation.
