SPECIFICATIONS

Supply voltage (AVDD) = 3.3 V, TA = 25°C, master clock = 12.288 MHz (48 kHz fS, 256 × fS mode), input sample rate = 48 kHz, measurement

bandwidth = 20 Hz to 20 kHz, word width = 24 bits, CLOAD (digital output) = 20 pF, ILOAD (digital output) = 2 mA, VIH = 2 V, VIL = 0.8 V,

unless otherwise noted. Performance of all channels is identical, exclusive of the interchannel gain mismatch and interchannel phase

deviation specifications.

ANALOG PERFORMANCE SPECIFICATIONS, TA = 25°C

IOVDD = 3.3 V ± 10%.
