The MAX9001–MAX9005 are combinations of a high-
speed operational amplifier, a 185ns comparator, and a
1%-accurate, 8ppm/°C, 1.230V reference. The devices
are offered in space-saving 8-pin and 10-pin µMAX pack-
ages. The comparator’s inverting input is internally con-
nected to the reference output in the MAX9000/MAX9003.
The MAX9002/MAX9005 do not have an internal refer-
ence, but the inverting input of the comparator is avail-
able externally. The MAX9001/MAX9004 include both the
inverting input and the reference output. The MAX9000/
MAX9001/MAX9003/MAX9004 typically consume only
410µA of quiescent current, while the MAX9002/
MAX9004 typically consume 340µA. These low-power,
Rail-to-Rail devices provide excellent AC and DC perfor-
mance and are ideally suited to operate from a single
supply. The MAX9001/MAX9004 feature a shutdown
mode that sets the outputs in a high-impedance state and
reduces the supply current to 2µA, making these devices
ideal for portable and battery-powered systems.
The op amps in the MAX9000/MAX9001/MAX9002 are
unity-gain stable with a gain-bandwidth product of
1.25MHz and a slew rate of 0.85V/µs. The amplifiers in
the MAX9003/MAX9004/MAX9005 are stable at closed-
loop gains greater than or equal to 10V/V, with a gain-
bandwidth product of 8MHz and a slew rate of 6.0V/µs.
The common-mode input voltage range extends from
150mV below the negative rail to within 1.2V of the pos-
itive rail. The amplifier output does not undergo phase
reversal when the common-mode input range is
exceeded, and the input impedance is relatively con-
stant for input voltages within both supply rails. The
MOS differential inputs of the amplifiers feature
extremely high input impedance and ultra-low input
bias currents. The CMOS output stage achieves true
rail-to-rail operation; the outputs swing to within a few
millivolts of the supply rails, thus extending the dynamic
range. A proprietary design achieves high open-loop
gain, enabling these devices to operate at low quies-
cent currents yet maintain excellent DC and AC char-
acteristics under various load conditions. These
devices have been designed to maintain low offset volt-
age over the entire operating-temperature, common-
mode, and supply-voltage ranges.
