_______________General Description

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 instability

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 equiva-

lent speed at a fraction of the power. The MAX912 dual

comparator has equal performance to the MAX913 and

includes independent latch controls.
