Analog Gain of Balanced Amplifier
The DAC voltage outputs are followed by balanced amplifier stages, which sum the differential signals for each
channel, creating a single-ended voltage output. In addition, the balanced amplifiers provide a third-order
low-pass filter function, which band limits the audio output signal. The cutoff frequency and gain are determined
by external R and C component values. In this case, the cutoff frequency is 77 kHz with a gain of 1.83. The
output voltage for each channel is 5.9 V p-p, or 2.1 V rms.
Application for Monaural-Mode Operation
A single-channel signal from the stereo audio data input is output from both VOUTL and VOUTR as a differential
output. The channel to be output is selected by setting the CHSL bit in register 20. The advantage of monaural
operation is to provide over 115 dB of dynamic range for high-end audio applications.
