Video ICs  
VCR Hi-Fi audio signal REC / PB  
amplifier with flying-erase oscillator  
BA7745FS  
The BA7745FS has the recording and playback amplifiers required for Hi-Fi VCR signal processing, and also con-  
tains a flying-erase oscillator. The recording system uses a constant-current amplifeir with AGC to eliminate the need  
to adjust the recording current, and ensure stable operation as the head wears. The IC also features REC MUTE and  
OVER REC functions .  
The playback system has a high-gain preamplifier, a low-offset head switch, a VCA and an EP-gain amplifier. The  
flying-erase oscillator has low 2nd and 3rd harmonic distortion, and when connected to an external driver large out-  
put current can be obtained.  
A H / L control system eliminates the need for special power supplies for the recording and playback systems. The  
IC has low power consumption, and comes in a compact 32-pin SSOP-P package that requires little area on the  
PCB. It will improve the reliability and performance of your designs while reducing external component requirements.  
Applications  
VCRs  
Features  
The low-noise playback amplifier has a total gain of  
83dB (Typ.). Designed for VHS-bandoperation with  
low external parts count. It has two built-in circuits for  
Hi-Fi VCR operation.  
7) Built-in recording level AGC eliminates the need to  
adjust recording current.  
8) Built-in low-pass filter limits the input bandwidth of  
the recording amplifier.  
2) The circuit has been designed to suppress head-  
switching noise.  
9) Built-in OVER REC recording current amplifier  
function and REC MUTE function that stops record-  
ing output.  
3) Built-in EP / SP gain switching function that boosts  
the playback gain by 5dB.  
10) Built-in high-frequency oscillator for use with flying  
erase function.  
4) Built-in VCA for easy playback output adjustment.  
5) High-output recording amplifier for audio FM record-  
ing.  
11) Record / playback switching can be done directly  
via the system controller, and consumes litlle  
power.  
6) Constant-current drive provides stable recording  
characteristics when the load (head impedance) is  
fluctuating.  
12) Possible to construct a high-performance audio  
system by pairing this chip with a Hi-Fi-audio signal  
processing IC.
