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.
