Renesas Quad, 3.5MHz, Operational Amplifier

Consisting of four amplifiers on a single chip, the HA-4741 provides a new measure of general-purpose operational amplifier performance, each with operating specifications equal to or exceeding the Type 741 amplifier in all performance categories. Due to its low input bias voltage (0.5mV), input bias current (60nA), and input voltage noise (9nV/ Hz at 1kHz) values, it is well suited for applications requiring precise signal processing.

Pinout

The 3.5MHz bandwidth, coupled with high open-loop gain, allows the HA-4741 to be used in designs that require amplification of broadband signals, such as audio amplifiers. Audio applications further enhance the HA-4741's negligible output crossover distortion. These excellent dynamic characteristics also make HA-4741 an ideal choice for various active power filter designs.

Test Circuit

The performance integrity of the multi-channel design is ensured by a high level of amplifier to amplifier isolation (69dB at 10kHz). A wide range of supply voltage (± 2 v to ± 20 v) can be used for power supply, the HA - 4741 to make it compatible with almost any system, including battery powered equipment.
