The output ac load during test is 5 pF (Refer to equivalent circuits Figures 5 and 6). 4IIH and IIL are valid for differential input voltages of less than 1.5 V. At higher differential voltages, the input current will increase to a maximum of 1.5 mA. 5Power dissipation is measured under the following conditions: analog input is –1 dBFS at 19.7 MHz. 6Typical thermal impedance for the ST-44 (LQFP) 44-lead package (in still air): θJC = 20°C/W, θCA = 35°C/W, θJA = 55°C/W. 7A change in input offset voltage with respect to a change in VDD. 8SNR/harmonics based on an analog input voltage of –1.0 dBFS referenced to a 1.024 V full-scale input range. Specifications subject to change without notice.
