Manufacturer:AD Description:Before the A/D digitizing the voice-band analog signal into digital format, the analog signal can be processed by a built-in Automatic Level Control (ALC) and pro- grammable Gain Amplifier (PGA). The ALC circuit controls the input level of A/D converter to about 1.5 Volt, so as to get a better signal to noise ratio during a low-level input. The PGA circuit is used to control the gain of different sources : microphone, aux or line input. After the digital data is converted into analog signal by the D/A converter, a fully differential line driver is supported to drive the telephone line directly without the need of external amplifier. On the other hand, the analog signal can be monitored by passing the analog signal to the on-chip volume control circuit, which can drive an external driver like LM386. |
