Description
Single/dual, Ultra-fast, Low-power, Precision Ttl Comparators
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX913 single and MAX912 dual, high-speed,
low-power comparators have differential inputs and
complementary TTL outputs. Fast propagation delay
(10ns, typ), extremely low supply current, and a wide
common-mode input range that includes the negative
rail make the MAX912/MAX913 ideal for low-power,
high-speed, single +5V (or ±5V) applications such as
V/F converters or switching regulators.
The MAX912/MAX913 outputs remain stable through
the linear region. This feature eliminates output instabili-
ty common to high-speed comparators when driven
with a slow-moving input signal.
The MAX912/MAX913 can be powered from a single
+5V supply or a ±5V split supply. The MAX913 is an
improved plug-in replacement for the LT1016. It pro-
vides significantly wider input voltage range and equiv-
alent speed at a fraction of the power. The MAX912
dual comparator has equal performance to the MAX913
and includes independent latch controls.
