Note 2: SNR calculation includes distortion and noise components. Note 3: Sample tested at TA = 25 °C to ensure compliance. Note 4: All digital inputs at GND except for CS at V DD. All digital outputs are unloaded. Analog inputs are connected to GND. Note 5: SCLK is at GND when SCLK is off. All digital inputs are at GND except for CS at VDD. All digital outputs are unloaded. Analog inputs are connected to GND. |
