The Intersil HA-4741/883, which contains four amplifiers on a monolithic chip, provides a new measure of performance for general purpose operational amplifiers. Each amplifier in the HA-4741/883 has operating specifications that equal or exceed those of the 741-type amplifier in all categories of performance.

The HA-4741/883 is well suited to applications requiring accurate signal processing by virtue of its low values of input offset voltage (3mV max), input bias current (200nA max) and input voltage noise (9nV/√Hz typ at 1kHz). The 2.5MHz bandwidth, coupled with high open loop gain, allow the HA-4741/883 to be used in designs requiring amplifiers of wideband signals, such as audio amplifiers. Audio application is further enhanced by the HA-4741/883�fs negligible output crossover distortion. These excellent dynamic characteristics also make the HA- 4741/883 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 (66dB at 10kHz).

A wide range of supply voltages (±2V to ±20V) can be used to power the HA-4741/883, making it compatible with almost any system including battery-powered equipment.
