17. Valid with the recommended capacitor values on FILT+ and VQ. Increasing the capacitance will also
increase the PSRR.
18. The PGA is biased with VQ, created from a resistor divider from the VA supply. Increasing the capaci-
tance on VQ will also increase the PSRR at low frequencies. A 10 µF capacitor on VQ improves the
PSRR to 42 dB.
