HA-4741
Data Sheet September 1998 File Number 2922.3
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. HA-4741/883 product and data sheets available upon request.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES: 1. Maximum power dissipation, including output load, must be designed to maintain junction temperature below 175oC for the ceramic package, and below 150oC for the plastic packages. 2. JA is measured with the component mounted on an evaluation PC board in free air. 3. One amplifier may be shorted to ground indefinitely.
