KA8603
UNIVERSAL SPEECH NETWORK
INTRODUCTION
The KA8603 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 KA8603 can be operated down to
D.C line 1.6V.
16-DIP-300A
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)
