Typical Operating Characteristics
(VDD = 3.0V, OVDD = 1.8V, VREFIN = VDD (internal reference), CL
≈ 10pF at digital outputs, differential input at -0.5dB FS, fCLK =
7.500567MHz at 50% duty cycle, TA = +25°C, unless otherwise noted.)
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.0V, OVDD = 1.8V, VREFIN = VDD (internal reference), CL
≈ 10pF at digital outputs, fCLK = 7.5MHz, CREFP = CREFN = CCOM
= 0.33F, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
Note 1: Specifications
≥+25°C guaranteed by production test, <+25°C guaranteed by design and characterization.
Note 2: SNR, SINAD, SFDR, HD3, and THD are based on a differential analog input voltage of -0.5dB FS referenced to the
amplitude of the digital output. SNR and THD are calculated using HD2 through HD6.
Note 3: The power consumption of the output driver is proportional to the load capacitance (CL).
Note 4: Guaranteed by design and characterization. Not production tested.
Note 5: SINAD settles to within 0.5dB of its typical value.
Note 6: Crosstalk rejection is measured by applying a high-frequency test tone to one channel and a low-frequency tone to the
second channel. FFTs are performed on each channel. The parameter is specified as power ratio of the first and second
channel FFT test tone bins.
Note 7: Amplitude/phase matching is measured by applying the same signal to each channel, and comparing the magnitude and
phase of the fundamental bin on the calculated FFT.
