Note 1: The TSA7887’s temperature range is –40°C to +125°C for both A and B versions.
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 VDD. 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.
