BA3304F 3V Dual Preamplifier

of circuit (see Fig. 1) As shown in the equivalent circuit for the BA3304 in Fig. 1, the first stage is a differential amplifier. This gives good stability with respect to temperature and supply voltage variation, and improves resistance to earth and power supply noise. The second stage uses Darling.

BA3304F Features

* 1) Low noise (VNIN = 1.2µVrms). 2) Input coupling capacitors not required. 3) No input coupling capacitors means high bass stability. 4) Good channel balance. 5) Built-in bias circuit minimizes “pop” noise. 6) Emitter-follower output for low output impedance. 7) Good low voltage characteristics (op
