MB3712 Description

Short technical summary and product information.

The MB3712 is a power audio amplifier designed by Fujitsu Semiconductor for consumer applications. It features a wide supply voltage range from 9V to 18V and a fixed voltage gain of 52.5 dB. The amplifier's unique input stage allows for ground-referenced input signals, and its output automatically self-centers to one-half of the supply voltage.

 

Key electrical characteristics include a low quiescent current of 60mA, a high peak current capability of 4.5A, and low distortion of 0.2% at 1W output into a 2Ω load. The input impedance is 50kΩ. The MB3712 is housed in a SIP_7P_2.54A package.

 

Typical applications for the MB3712 include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, and sound projector systems.
