Op Amp + Comparator + Reference ICs
General Description Features
The MAX9000 family features the combination of a high-
' Op Amp + Comparator + Reference in
speed operational amplifier, a 185ns comparator, and a
Space-Saving MAX Package
precision 1.230V reference. These devices operate from a
' +2.5V to +5.5V Single-Supply Voltage Range
single +2.5V to +5.5V supply and draw less than 500A of
quiescent current. The MAX9001/MAX9004 feature a shut- ' 340A Supply Current (MAX9002/MAX9005)
down mode that reduces supply current to 2A and puts

ideal for portable and battery-powered applications.
' Op-Amp/Comparator Outputs Swing Rail-to-Rail
The amplifiers in the MAX9000/MAX9001/MAX9002 are
unity-gain stable with a 1.25MHz gain-bandwidth product, ' Ground-Sensing Inputs for Both Op Amp and
while the amplifiers in the MAX9003/MAX9004/MAX9005

are stable for closed-loop gains of +10V/V or greater with
' Op Amp Stable with Capacitive Loads up to 250pF
an 8MHz gain-bandwidth product. The input common-
' Internal 2mV Comparator Hysteresis
mode voltage extends from 150mV below the negative
supply to within 1.2V of the positive supply for the amplifi-
' Fast 185ns Propagation-Delay Comparator
er, and to within 1.1V for the comparator. The amplifier and
' No Phase Reversal for Overdriven Inputs
comparator outputs can swing Rail-to-Rail and deliver up
(Both Op Amp and Comparator)
to 2.5mA and 4.0mA, respectively, to an external load
while maintaining excellent DC accuracy. The unique
