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 T
A
= 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.
