6.1.1
The ADC consists of two second order Sigma Delta converters allowing two separate channels that are
identical in functionality.
ADC Sample Rates
Each ADC supports the following sample rates:
ADC Gain
The ADC contains two gain stages for each channel, an analogue and a digital gain stage.
The digital gain stage has a range of –24dB to +21.5dB.
The ADC analogue amplifier is a two stage amplifier. The first stage of the analogue amplifier is responsible
for selecting the correct gain for either microphone input or line input and therefore has two gain settings,
one for the microphone and one for the line input. In simple terms the first stage amplifier has a selectable
20dB gain stage for the microphone and this creates the dual programmable gain required for the
microphone or the line input. The equivalent block diagram for the two stage is shown in the figure below.
The second stage of the analogue amplifier has a programmable gain with seven individual 3dB steps. In
simple terms, by combining the 20dB gain selection of the microphone input with the seven individual 3dB
gain steps, the overall range of the analogue amplifier is approximately -4dB to 40dB. The overall gain
setting of the ADC is a combined function of the digital and analogue amplifier settings, so that the fullscale
range of the input to the ADC is kept to approximately 400mV rms.
