Test Conditions/Comments
Over a dynamic range of 100 to 1, PGA = 1, 2, 4, 8
PGA = 1, differential inputs between the
following pins: IAP and IAN, IBP and IBN, ICP
and ICN; single-ended inputs between the
following pins: VAP and VN, VBP and VN, VCP,
and VN
PGA = 1, uncalibrated error, see the Terminology
section
External 1.2 V reference
Sampling CLKIN/2048, 16.384 MHz/2048 = 8 kSPS
See the Waveform Sampling Mode section
PGA = 1, fundamental frequency: 45 Hz to
65 Hz, see the Terminology section
PGA = 1; fundamental frequency: 45 Hz to
65 Hz, see the Terminology section
Line frequency = 45 Hz to 65 Hz, HPF on
WTHR = VARTHR = VATHR = PMAX = 33,516,139
If CF1, CF2, or CF3 frequency > 6.25 Hz and
CFDEN is even and > 1
If CF1, CF2, or CF3 frequency > 6.25 Hz and
CFDEN is odd and > 1
If CF1, CF2, or CF3 frequency < 6.25 Hz
For CF1, CF2, or CF3 frequency = 1 Hz and
nominal phase currents are larger than 10% of
full scale
Minimum = 1.2 V − 8%; maximum = 1.2 V + 8%
Nominal 1.2 V at the REFIN/OUT pin at TA = 25°C
Drift across the entire temperature range of −40°C
to +85°C is calculated with reference to 25°C;
see the Reference Circuit section for more details
All specifications CLKIN of 16.384 MHz. See the
Crystal Circuit section for more details.
VDD = 3.3 V ± 10%
VDD = 3.3 V ± 10%
Input = 0 V, VDD = 3.3 V
