Dual preamplifier with mute function
BA3406AF
The BA3406AF is a multi-function dual-channel preamplifier with a built-in mute circuit and a time-constant switching circuit for use with metal tape. The output circuits have diodes, and can be connected to other circuits in parallel, which eliminates the need for switches. The mute circuit is independent of the preamplifier block, and can be used to mute the whole system. FApplications Car stereos, radio cassette players, and tape decks FFeatures 1) Wide operating power supply voltage range (6V to 14V). 2) Low noise (VNIN = 1.0µVrms Typ.). 3) High open loop voltage gain (GVO = 80dB Typ. at pins 1 and 15). 4) Two channels on one chip, providing good channel balance. 5) Emitter-follower outputs for low output impedance.
