Functional Description
Power Supply Range This IC is designed to operate on single supply, shown by table 1. Table 1
Item Single Supply
Spply Voltage
Power Supply Range 9.5V to 15.0V
Reference Voltage So little is the current drivability of AC reference (Vref) that the Vref voltage may be altered by A/B switching of PB-EQ. Provided it causes you anxiety, please use the constant 1/2 VCC voltage circuit, for example, figure 1. In addition, this IC has a capacitor charger for Vref pin.

Block Diagram
This IC can be constructed for simple system which has little external parts by used the head serving both as Recording and Play back because of REC return SW built-in. With output Hi-Z of REC-EQ and input muting, this IC is realized not only REC mute attenuation sufficiently but reducing pop noise in REC muting. Note: Referring to Parallel Data Format also.

Level Diagram It is the target that total play back output level is adjusted to 300mV; Dolby level, which the PB system gain in all is included of external amplifier's (Dolby IC etc.) as follows figure 3. Though A head adjustment is independent of B, select the value of R9, R18 adequately. Regarding REC-EQ adjust the gain in front of input to this IC. The level diagram at 1kHz is shown by figure 4. Note: 1. R1 needs the value more than 1kHz. 2. Depending on the employed REC/PB head and test tape characteristics, there is rare case that the REC-EQ frequency characteristics of this IC can not be matched to the required characteristics because of built-in resistors which determined the REC-EQ parameters in this case, please inquire the responsible agent because of the adjustment of built-in resistors is necessary.
