DDA
Input impedance of MIC and AUX when selected
as the A/D input:
Input impedance of MIC and AUX when not
selected as the A/D input
Maximum source or sink current of MIC or AUX
when not selected as the A/D input
Input capacitance on MIC and AUX
Peak input voltage on the MIC/AUX input for full
scale linearity at V
Absolute gain variation due to V
all A/D and D/A gain settings (0.83 dB due to 10%
variation on V
A/D absolute gain variation due to internal
circuitry for all A/D gain settings (variation from
ideal VRAD of 0.5 V
D/A absolute gain variation due to internal
circuitry for all D/A gain settings (variation from
ideal VRDA of 0.5 V
VRDA and VRAD output voltage plus offset
(assumes no leakage current on the VDIV pin and
VDDA = 5.000 V)
SPKP, SPKM, VRDA, and VRAD output current
VDIV AC input impedance
VDIV I/O voltage plus offset (assumes there is not
leakage current on the I/O and V
Differential DC offset between SPKP and SPKM
Single-ended DC offset of SPKP and SPKM with
respect to VRDA
