Notice:
Stresses above those listed under "Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
those or any other conditions above those indicated in the
operation listings of this specification is not implied. Exposure
to maximum rating conditions for extended periods may affect
device reliability.

Note
1:
This parameter is established by characterization and not 100% tested.
2:
INL is the difference between the endpoints line and the measured code at the center of the quantization band.
3:
This current is due to the leakage current and the current due to the offset voltage between V
IN
+ and V
IN
-.
4:
Input impedance is inversely proportional to clock frequency; typical values are for the MCP3551 device. V
REF
= 5V.
5:
Characterized by design, but not tested.
6:
Rejection performance depends on internal oscillator accuracy; see
Section 4.0 “Device Overview”
for more informa-
tion on oscillator and digital filter design. MCP3551 device rejection specifications characterized from 49 to 61 Hz.
