ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3V, OVDD = 1.8V, internal reference (1.024V), CL ≈ 10pF on all digital outputs, fCLK = 7.5MHz (50% duty cycle), ADC input
amplitude = -0.5dBFS, DAC output amplitude = 0dBFS, differential ADC input, differential DAC output, CREFP = CREFN = CCOM =
0.33F. Typical values are at TA = +25°C, unless otherwise noted. CL < 5pF on all aux-DAC outputs.) (Note 1)
