KA8601C
SPEAKER PHONE WITH SPEECH NETWORK
INTRODUCTION
The KA8601C is a monolithic integrated circuit for use in high perfor-
mance speaker phone system.
The KA860lC consists of speaker phone and speech network. Speaker
phone includes attenuators, amplifiers, level detectors, attenuator
control, hybrid amplifiers, regulator and AGC circuit. Speech network
includes transmit amp, receive amp, voltage regulator for dialer, side
tone control, and line equalizer.
48-SDIP-600
FEATURES
• Speaker Phone
- Low Operating Voltage (3.0 ~ 6.5V)
- High Attenuator Gain Range (52dB)
- Improved Sensitivity (Four-point Signal Sensing)
- Chip Disable for Active or Standby Operation
- Microphone Amp Gain set by External Components
• Speech Network
- Low Operating Voltage (1.5V : speech)
- Regulated Voltage for Dialer (Typically 3.3V)
- Transmit, Receive, Side Tone Gains set by
External Components
- Mute Input for DTMF Dialing
