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: Guaranteed by design and characterization.
Note 3: The minimum clock frequency (fCLK) for the MAX19708 is 1.5MHz (typ). The minimum aux-ADC sample rate clock frequen-
cy (ACLK) is determined by fCLK and the chosen aux-ADC clock-divider value. The minimum aux-ADC ACLK > 1.5MHz /
128 = 11.7kHz. The aux-ADC conversion time does not include the time to clock the serial data out of the SPI. The maximum
conversion time (for no averaging, NAVG = 1) will be tCONV (max) = (12 x 1 x 128) / 1.5MHz = 1024s.
Note 4: 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 5: 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 6: 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.
