9.Audio Codec
The DLBM-CA120 CODEC is compatible with the direct speaker drive and microphone input
using a minimum number of external components. It is primarily intended for voice
applications and it is fully operational from a single 1.8 Volt power supply. A fully differential
architecture has been implemented for optimal power supply rejection and low noise
performance. The digital format is 15-bit/sample linear PCM with a data rate of 8kHz.
The CODEC has an input stage containing a microphone amplifier, variable gain amplifier
and a - ADC. Its output stage contains a DAC, low-pass filter and output amplifier. The
CODEC functional diagram is shown below:

10. Input Stage
A low noise variable gain amplifier amplifies the signal difference between inputs MIC_N
and MIC_P. The input may be from either a microphone or line. The amplified signal is then
digitised by a - ADC. The high frequency single bit output from the ADC is converted to
15-bit 8kHz linear PCM data.
The gain is programmable via a PSKEY and has a 42dB range with 3dB resolution. At
maximum gain the full scale input level is 3mV rms. A bias network is required for operation
