6. Note on Connecting with Tape Head to IC
This IC has no internal resistor to give the DC bias current to equalizer amp, therefore the DC bias
current will give through the head. This IC provides the Vref buffer output pin for Rch and Lch
separately (has two Vref terminal). In case of use that the Rch and Lch reference of head are
connected commonly, please use one of Vref terminals of IC (47 pin or 52 pin) for head reference.
If both 47 pin and 52 pin of IC are connected, rush current give the great damage to IC. The
application circuit is shown in figure 3.
