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 (fCLK) for the MAX19707 is 7.5MHz (typical). The minimum aux-ADC sample rate clock fre-
quency (ACLK) is determined by fCLK and the chosen aux-ADC clock-divider value. The minimum aux-ADC ACLK >
7.5MHz / 128 = 58.6kHz. 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) / 7.5MHz = 205s.
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.
