General Description

The MAX9000 family features the combination of a high­speed operational amplifier, a 185ns comparator, and a
precision 1.230V reference. These devices operate from a
single +2.5V to +5.5V supply and draw less than 500µA of
quiescent current. The MAX9001/MAX9004 feature a shut­down mode that reduces supply current to 2µA and puts
the outputs into a high-impedance state, making them
ideal for portable and battery-powered applications.

The amplifiers in the MAX9000/MAX9001/MAX9002 are
unity-gain stable with a 1.25MHz gain-bandwidth product,
while the amplifiers in the MAX9003/MAX9004/MAX9005
are stable for closed-loop gains of +10V/V or greater with
an 8MHz gain-bandwidth product. The input common­mode voltage extends from 150mV below the negative
supply to within 1.2V of the positive supply for the amplifi­er, and to within 1.1V for the comparator. The amplifier and
comparator outputs can swing Rail-to-Rail®and deliver up
to ±2.5mA and ±4.0mA, respectively, to an external load
while maintaining excellent DC accuracy. The unique
design of the comparator output stage substantially
reduces switching current during output transitions, virtually
eliminating power-supply glitches.

The comparator’s ±2mV of built-in hysteresis provides
noise immunity and prevents oscillations even with a
slow-moving input signal. The MAX9000/MAX9001/
MAX9003/MAX9004 have an internal 1.230V ±1% preci­sion reference with a low 8ppm/°C temperature coeffi­cient that can sink or source up to 1mA. The amplifier and
reference are stable with capacitive loads up to 250pF
and 100nF, respectively. The comparator’s inverting input
is internally connected to the reference output in the
MAX9000/MAX9003.
