Analog Devices MAX98502EVKIT#

General Description

The MAX985/MAX986/MAX989/MAX990/MAX993/MAX994 single/dual/quad micropower comparators feature low-voltage operation and rail-to-rail inputs and outputs. Their operating voltages range from 2.5V to 5.5V, making them ideal for both 3V and 5V systems. These comparators also operate with ±1.25V to ±2.75V dual supplies. They consume only 11µA of supply current while achieving a 300ns propagation delay.

Features

♦ 11µA Quiescent Supply Current
♦ 2.5V to 5.5V Single-Supply Operation
♦ Common-Mode Input Voltage Range Extends 250mV Beyond the Rails
♦ 300ns Propagation Delay
♦ Push-Pull Output Stage Sinks and Sources 8mA Current (MAX985/MAX989/MAX993)
♦ Open-Drain Output Voltage Extends Beyond VCC (MAX986/MAX990/MAX994)
♦ Unique Output Stage Reduces Output Switching Current, Minimizing Overall Power Consumption
♦ 80µA Supply Current at 1MHz Switching Frequency
