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)

Note 1: Specifications from TA = +25°C to +85°C are guaranteed by production tests. Specifications from TA = +25°C to -40°C are
guaranteed by design and characterization.
Note 2: The minimum clock frequency for the MAX19700 is 2MHz.
Note 3: SNR, SINAD, SFDR, HD3, and THD are based on a differential analog input voltage of -0.5dBFS referenced to the amplitude
of the digital outputs. SINAD and THD are calculated using HD2 through HD6.
Note 4: 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 the power ratio of the first and second channel
FFT test tone.
Note 5: Amplitude and phase matching is measured by applying the same signal to each channel, and comparing the two output
signals using a sine-wave fit.
Note 6: Guaranteed by design and characterization.
