Note 1:
Specifications from T
A
= +25°C to +85°C guaranteed by production tests. Specifications at T
A
< +25°C guaranteed by
design and characterization.
Note 2:
The minimum clock frequency (f
CLK
) for the MAX19713 is 7.5MHz (typ). The minimum aux-ADC sample rate clock frequency
(A
CLK
) is determined by f
CLK
and the chosen aux-ADC clock-divider value. The minimum aux-ADC A
CLK
> 7.5MHz / 128 =
58.6kHz. The aux-ADC conversion time does not include the time to clock the serial data out of DOUT. The maximum con-
version time (for no averaging, NAVG = 1) will be t
CONV
(max) = (12 x 1 x 128) / 7.5MHz = 205μs.
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 sec-
ond channel. FFTs are performed on each channel. The parameter is specified as the power ratio of the first and second
channel FFT test tones.
Note 5:
Amplitude and phase matching are 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.
