DIGITAL SPECIFICATIONS

AVDD1 = 0.975 V, AVDD1_SR = 0.975 V, AVDD2 = 1.9 V, AVDD3 = 2.5 V, DVDD = 0.975 V, DRVDD1 = 0.975 V, DRVDD2 = 1.9 V, SPIVDD

= 1.9 V, specified maximum sampling rate, 1.54 V p-p full-scale differential input, AIN = −2.0 dBFS, L = 4, M = 1, F = 1, and −20°C ≤ TJ ≤

+100°C, unless otherwise noted. The TJ range of −20°C to +100°C translates to a TA range of −40°C to+85°C. Typical specifications represent

performance at TJ = 40°C (TA = 25°C).
