A | Page 4 of 20 Test 105 MSPS 125 MSPS Parameter Temp Level Min Typ Max Min Typ Max Unit DIGITAL OUTPUTS Logic 1 Voltage Full VI VDD − 0.05 VDD − 0.05 V Logic 0 Voltage Full VI 0.05 0.05 V Output Coding Twos complement or offset binary 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. Table 2.
