SDC04 Analog Channel Differential
Input Voltage Range
——±SV
DD V Limit differential input to
±[(SV
REF+ – SVREF-)/GAIN]
for non-saturated result
SDC05 INL Integral Linearity Error -20 6 +20 LSb See Figure 37-8
SDC06A Offset Error -12 10 +12 mV 1x Gain mode without using
VOSCAL, offset error is mostly
independent of gain setting
SDC06B — 0.0 — mV 1x Gain mode, after VOSCAL
based firmware correction
SDC08 Unadjusted Gain Error -10 -6 -0.001 % 1x Gain mode uncorrected
SDC09B
SINAD
— 75 — dB OSR 1024, high dithering
enabled, 25 Hz input
SDC10 Differential Input Impedance — 684 — kΩ 4 MHz A/D clock, input
impedance is proportional to
1/(A/D Clock Frequency)
SDC13 A/D Clock Input Frequency 1 — 4 MHz
SDC14 SV
DD Operating Current — 3.6 — mA Module enabled, 4 MHz A/D
clock, SV
DD/SVSS as A/D

Note 1: Unless otherwise stated, typical column test conditions are with V
DD = AVDD = SVDD = 3.3V, +25°C,
1x Gain mode, OSR 1024, chopping enabled, SV
DD/SVSS are used as A/D references.
