MAX900BEWP

Overview

The MAX900BEWP is a quad general-purpose analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels in a 20-SOIC surface-mount package. Key electrical specifications include an 8 ns response time, a supply voltage range of 5 V to 10 V, and a typical input offset voltage of 4 mV. The device operates with a supply current of 15 mA and supports push-pull outputs capable of sourcing or sinking 8 mA per channel. It offers high common-mode rejection of 82.5 dB and power supply rejection of 80 dB, functioning within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent general-purpose comparators in a single compact package
• Features fast 8 ns propagation delay for high-speed signal processing applications
• Provides robust noise immunity with 82.5 dB common-mode rejection ratio
• Delivers strong output drive capability via push-pull TTL-compatible stages

Applications

• General-purpose voltage threshold detection circuits
• High-speed digital interface level shifting
• Over-voltage and under-voltage protection monitoring
• Pulse width modulation (PWM) generation circuits

Procurement Notes

Verify the specific suffix BEWP confirms the 20-SOIC package and commercial temperature grade. Confirm end-of-life status as some sources indicate discontinuation. Ensure compatibility with existing PCB footprints for SOIC-20 components. Check for lead-free RoHS compliance if required by assembly standards. Validate that the 5V-10V supply range meets system power constraints.

Selection Notes

Select this component when multiple comparator channels are needed in a space-constrained design. It is suitable for applications requiring moderate speed and standard logic-level outputs. Consider alternatives if rail-to-rail input operation or lower supply voltages below 5V are required. Evaluate thermal dissipation capabilities given the 500 mW power dissipation rating in the SOIC package.

Part Context

This part belongs to the MAX900 series of quad comparators from Maxim Integrated. It serves as a cost-effective solution for multi-channel comparison tasks where high precision is not critical but speed and integration density are valued. The series typically includes variants with different packages and temperature ranges to support diverse industrial and consumer electronics designs.
