NOTE 7: The input signal is the digital equivalent of a 1020-Hz sine wave (digital full scale = 0 dB). The nominal differential DAC channel output

with this input condition is 6 V peak to peak.

NOTE 8: The input signal, VI, is the digital equivalent of a 1020-Hz sine wave (full-scale analog output at full-scale digital input = 0 dB). The nominal

differential DAC channel output with this input condition is 6 V peak to peak. The load impedance for the DAC output buffer is 600

Ω

from OUT + to OUT –.
