HA-4741
Quad, 3.5MHz, Operational Amplifier
HA-4741, which contains four amplifiers on a monolithic
chip, provides a new measure of performance for general
purpose operational amplifiers. Each amplifier in the
HA-4741 has operating specifications that equal or exceed
those of the 741-type amplifier in all categories of
performance.
HA-4741 is well suited to applications requiring accurate
signal processing by virtue of its low values of input offset
voltage (0.5mV), input bias current (60nA) and input voltage
noise (9nV/
√
Hz at 1kHz). 3.5MHz bandwidth, coupled with
high open-loop gain, allow the HA-4741 to be used in
designs requiring amplification of wide band signals, such as
audio amplifiers. Audio application is further enhanced by
the HA-4741’s negligible output crossover distortion.
These excellent dynamic characteristics also make the
HA-4741 ideal for a wide range of active filter designs.
Performance integrity of multi-channel designs is assured by
a high level of amplifier-to-amplifier isolation (69dB at
10kHz).
A wide range of supply voltages (
±
2V to
±
20V) can be used
to power the HA-4741, making it compatible with almost any
system including battery-powered equipment.
