Low Power, Single Supply
Operational Amplifiers
DUAL
Quality bipolar fabrication with innovative design concepts are employed
for the MC33171/72/74 series of monolithic operational amplifiers. These
devices operate at 180
µA
per amplifier and offer 1.8 MHz of gain bandwidth
product and 2.1 V/µs slew rate without the use of JFET device technology.
Although this series can be operated from split supplies, it is particularly
suited for single supply operation, since the common mode input voltage
includes ground potential (VEE). With a Darlington input stage, these devices
exhibit high input resistance, low input offset voltage and high gain. The all
NPN output stage, characterized by no deadband crossover distortion and
large output voltage swing, provides high capacitance drive capability,
excellent phase and gain margins, low open loop high frequency output
impedance and symmetrical source/sink AC frequency response.
The MC33171/72/74 are specified over the industrial/ automotive
temperature ranges. The complete series of single, dual and quad
operational amplifiers are available in plastic as well as the surface mount
packages.
