MAX965–MAX970
Single/Dual/Quad, Micropower,
Ultra-Low-Voltage, Rail-to-Rail I/O Comparators
General Description
Features
The MAX965–MAX970 single/dual/quad micropower
comparators feature rail-to-rail inputs and outputs, and
fully specified single-supply operation down to +1.6V.
These devices draw less than 5µA per comparator and
● Ultra-Low Single-Supply Operation down to +1.6V
● Rail-to-Rail Common-Mode Input Voltage Range
● 3µA Quiescent Supply Current per Comparator
● Open-Drain Outputs Swing Beyond V
have open-drain outputs that can be pulled beyond V
CC
CC
to 6V (max) above ground. In addition, their rail-to-rail
input common-mode voltage range makes these
comparators suitable for ultra-low-voltage operation.
● 1.235V ±1.5% Precision Internal Reference
(MAX965/967/968/969)
● 10µs Propagation Delay (50mV overdrive)
A +1.6V to +5.5V single-supply operating voltage range
makes the MAX965 family of comparators ideal for 2-cell
battery-powered applications. The MAX965/MAX967/
MAX968/MAX969 offer programmable hysteresis and an
internal 1.235V ±1.5% reference. All devices are available
● Available in Space-Saving Packages:
• 8-Pin µMAX (MAX965–MAX968)
• 16-Pin QSOP (MAX969/MAX970)
