INTRODUCTION
S1T8603
16- DIP- 300A
The S1T8603 can fulfill the standards of other countries by changing
the external component. Dynamic or piezoelectric type can be used
with receiver. Each gain is controlled with AGC in accordance with the
line current. The S1T8603 can be operated down to D.C line 1.6V.
