NOTE 17: Power-supply rejection measurements are made with both the ADC and the DAC channels idle and a 200-mV peak-to-peak signal
applied to the appropriate supply.

TEST CONDITIONS
ADC channel crosstalk attenuation
DAC channel idle with
DIN = 00000000000000,
ADC input = 0 dB,
1020-Hz sine wave,
Gain = 0 dB (see Note 18)
DAC channel crosstalk attenuation
ADC channel idle with INP, INM,
AUX IN +, and AUX IN – at ADC VMID
DAC channel input = digital equivalent of
a 1020-Hz sine wave (see Note 19)

NOTES: 18. The test signal is a 1020-Hz sine wave with a 0 dB = 6-V peak-to-peak reference level for the analog input signal.
19. 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. The load impedance for the DAC output buffer is 600 Ω from OUT + to OUT –.
