The output amplifier of all buffers can be adjusted using the AMPL pad (pad 6) in pad control mode. The amplitude is set to 300 mVpp differential if the pad is left open, 250 mVpp if the pad is tied to ground and 500 mVpp if the pad is tied to VCC (recommended mode of operation). In 2-wire control mode, the amplitude of each channel can be adjusted from 0mVpp to 600 mVpp. The amplitude is controlled with the AMPL[0..3] bits in registers 1, 7, 13 and 19 respectively for channels 1, 2, 3 and 4.
