... Audio ICs 3V dual preamplifier BA3304F The BA3304F is a monolithic, dual-preamplifier IC designed for 3V applications. It has been designed especially for low- voltage operation. The preamplifiers can be directly coupled to the head to minimize the “pop” noise at power on. When combined with the Rohm BA5204 simple matter to design a high-performance circuit for cassette players. ...

... The second stage uses Darlington pairs to increase the input impedance and the gain of the first stage. The out- put is an emitter follower which suppresses deterioration of the linearity due to the influence of the equalizer termi- nal, and prevents drop in maximum output. = 3V, f= 1kHz and BA3304F 179 ...

... R and R determines the bass cutoff frequency and C and C : equalizer terminal (NAB These components set the time constant for normal tape (120 s), and the tape speed to 4.75cm / s. The gain is 33dB at 1kHz. BA3304F ...

... Capacitive loads The BA3304F has an emitter-follower output, so oscilla- tion is apt to occur if the load is capacitive (if the capaci- tance of the load exceeds 150pF with V will occur). Oscillation is apt to occur if the closed-loop gain ( lower than 30dB 1kHz ...
