See Figure 11 for the equivalent analog input structure. 2 Measured with a 9.7 MHz, full-scale sine wave input, NCO enabled with a frequency of 13 MHz, FIR filter enabled and the fS/8 output mix enabled with approximately 5 pF loading on each output bit. 3 The maximum limit applies to the combination of IAVDD and IDVDD currents. 4 Standby power is measured with a dc input and with the CLK pin inactive (set to AVDD or AGND). |
