Note 1: VDD = 1.5V, VREF = 1.5V, and VAIN = 1.5V.
Note 2: VDD = 1.5V, VREF = 1.5V, VAIN = 1.5VP-P, fSCLK = 5MHz, fSAMPLE = 357ksps, and fIN (sine-wave) = 85kHz.
Note 3: All digital inputs swing between VDD and GND. VREF = VDD, fIN = 85kHz sine-wave, VAIN = VREFP-P, CLOAD = 30pF on DOUT.
Note 4: CS = VDD, OE = UNI/BIP = CH1/CH2 = VDD or GND, SCLK is active.
Note 5: CS = VDD, OE = UNI/BIP = CH1/CH2 = VDD or GND, SCLK is inactive.
Note 6: Change in VAIN at code boundary 1022.5.
