AN7148
Dual 2.1W Audio Power Amplifier Circuit
amplifier of 2.1W (9V, 4 ) output. Stereo operation is
enabled due to incorporating two amplifiers on one chip.
It is most suitably used for battery operated set such as
radio cassette recorder because quiescent circuit current
is small comparing to current power amplifier. Low distor-
tion and low noise are realized and external components
are very few. 12-pin SIL package has realized compact
and high density mounting of a set.
The AN7148 is an integrated circuit designed for power
Low quiescent current
High operation stability
Low radiation
Low distortion
Low noise
Low shock noise from power ON/OFF operation
Fewer external components
