BA3423S  
The BA3423S is a record/playback system preamplifier for radio cassette decks. With four control pins it allows switch-  
ing between I/O for the A (play only) and B (record and play) mechanisms, input for tape, radio, and microphone, on  
and off switching for line out and recording output, and equalizer switching for normal and high-speed dubbing.  
Itrequiresabouthalfthenumberofexternalcomponentsofitspredecessorswhichmeanssimplifiedassemblyandover-  
all cost savings.  
FApplications  
Dual-cassette radio cassette players.  
FFeatures  
1) Built-in switch for playback equalizer amplifier for the  
A and B mechanisms.  
6) Built-in ALC circuit.  
7) Built-in recording equalizer circuit, and internal  
switching of the normal/high-speed equalizer is  
possible.  
2) Built-in normal/high-speed equalizer switch for the  
playback equalizer amplifier.  
3) The B mechanism input is also used as the recording  
output, so a switch is not required.  
8) All stages are directly connected, so coupling ca-  
pacitors are not required.  
4) Built-in tape/radio input switch, and microphone mix-  
ing.  
9) Muting is applied as required during switching to re-  
duce switching noise (transition muting).  
10) Pin assignments has been designed to facilitate  
placement of attached components and PCB de-  
sign.  
5) The microphone amplifier is used as the mixing am-  
plifier, and the line can be muted to allow the built-in  
microphone to be used for recording.  
FAbsolute maximum ratings (Ta = 25_C)  
FRecommended operating conditions (Ta = 25_C)
