Differential Section
The PCM1796 voltage outputs are followed by differential amplifier stages, which sum the differential signals for each
channel, creating a single-ended I/V op-amp output. In addition, the differential amplifiers provide a low-pass filter
function.
The op amp recommended for the differential circuit is the low-noise type.
