Rail-to-Rail I/O Comparators

General Description

____________________________Features

ꢀ 11µA Quiescent Supply Current

The MAX985/MAX986/MAX989/MAX990/MAX993/

MAX994 single/dual/quad micropower comparators

ꢀ 2.5V to 5.5V Single-Supply Operation

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 ±±.25V to ±2.ꢀ5V

dual supplies. They consume only ±±µA of supply cur-

rent while achieving a 300ns propagation delay.

ꢀ Common-Mode Input Voltage Range Extends

250mV Beyond the Rails

ꢀ 300ns Propagation Delay

ꢀ Push-Pull Output Stage Sinks and Sources

Input bias current is typically ±.0pA, and input offset

voltage is typically 0.5mV. Internal hysteresis ensures

clean output switching, even with slow-moving input

signals.

8mA Current (MAX985/MAX989/MAX993)

ꢀ Open-Drain Output Voltage Extends Beyond V

(MAX986/MAX990/MAX994)

ꢀ Unique Output Stage Reduces Output Switching

The output stage’s unique design limits supply-current

surges while switching, virtually eliminating the supply

glitches typical of many other comparators. The

MAX985/MAX989/MAX993 have a push-pull output

stage that sinks as well as sources current. Large inter-

nal output drivers allow rail-to-rail output swing with

loads up to 8mA. The MAX986/MAX990/MAX994 have

an open-drain output stage that can be pulled beyond

Current, Minimizing Overall Power Consumption

ꢀ 80µA Supply Current at 1MHz Switching

Frequency

ꢀ No Phase Reversal for Overdriven Inputs

ꢀ Available in Space-Saving Packages:

UCSP (MAX985)

to 6V (max) above V . These open-drain versions

SOT23 (MAX985/MAX986/MAX989/MAX990)

µMAX (MAX989/MAX990)

are ideal for level translators and bipolar to single-

ended converters.

The single MAX985 is available in a chip-scale pack-

age (UCSP™), significantly reducing the required PC

board area. The single MAX985/MAX986 are available

in 5-pin SCꢀ0 packages and the dual MAX989/MAX990

are available in 8-pin SOT23 packages.
