and updated integrated circuit technologies, analog circuit
design techniques and processes in response to the needs
of the marketplace. The enhanced performance of newer
operational amplifiers and comparators has come through
innovative application of these technologies, designs and
processes. Some early designs are still available but are
giving way to the new, higher performance operational
amplifierand comparator circuits. Motorola has pioneered in
JFET inputs, low temperature coefficient input stages, Miller
loop compensation, all NPN output stages, dual–doublet
frequency compensation and analog “in–the–package”
trimming of resistors to produce superior high performance
operational amplifiers and comparators, operating in many
cases from a single supply with low input offset, low noise,
low power, high output swing, high slew rate and high
gain–bandwidth product at reasonable cost to the customer.
Present day operational amplifiers and comparators find
applications in all market segments including motor controls,
instrumentation, aerospace, automotive, telecommunications,
medical, and consumer products.
