Notes
1. At code 0000H.
2. Vripple = 1% of supply voltage and fripple = 100 Hz.
3. Measured with 1 kHz sinewave generated at a sampling rate of 192 kHz.
4. Measured with 1 kHz sinewave over a 20 Hz to 20 kHz bandwidth generated at a sampling rate of 192 kHz.
5. R3 = R4 = 11 kΩ; see Fig.1; IFS = 2 mA.
