Samsung S1T8603X01-S0B0, S1T8603X01-D0B0 Datasheet
UNIVERSAL SPEECH NETWORK S1T8603
1
INTRODUCTION
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.
FEATURES
• Independent adjustment of DC resistance and AC impedance.
• ECM or dynamic microphone can be used.
• DTMF signal interface.
• Mute function
• Operates at the low line voltage (1.6V)
• Low or high impedance receiver type can be used.
• Low line current operation. (IL = 4mA)
