NOTES:
1. Maximum power dissipation, including output load, must be designed to maintain junction temperature below 175 for the ceramic package,and below 150 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.DescriptionHA-4741, which contains four amplifiers on a monolithic chip, provides a new measure of performance for general purpose operational amplifiers. Each amplifier in the product 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 product 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.
