All typical values are at VDD = 5 V and TA = 25°C.
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.

All typical values are at VDD = 5 V and TA = 25°C.
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
from OUT+ to OUT–.
