Twos complement or offset binary
1 Gain error and gain temperature coefficients are based on the ADC only (with a fixed 2.5 V external reference and a 2 V p-p differential analog input).
2 SFDR mode disabled (SFDR MODE = GND) for DNL and INL specifications.
3 Power dissipation measured with rated encode and a dc analog input (outputs static, IVDD = 0). IVCC and IVDD measured with 10.3 MHz analog input @ 0.5 dBFS.
AC SPECIFICATIONS
VDD = 3.3 V, VCC = 5 V; differential encode input, unless otherwise noted.
