AC SPECIFICATIONS
AVDD1 = 0.975 V, AVDD1_SR = 0.975 V, AVDD2 = 1.8 V, AVDD3 = 2.5 V, DVDD = 0.975 V, DRVDD1 = 0.975 V, DRVDD2 = 1.8 V,
SPIVDD = 1.8 V, specified maximum sampling rate, clock divider = 4, 1.8 V p-p full-scale differential input, 0.5 V internal reference,
AIN = −1.0 dBFS, default SPI settings, unless otherwise noted. Minimum and maximum specifications are guaranteed for the full
operating junction temperature (TJ) range of −40°C to +105°C. Typical specifications represent performance at TJ = 50°C (TA = 25°C).
