Parameters
This parameter is established by characterization and not 100% tested.
INL is the difference between the endpoints line and the measured code at the center of the quantization band.
This current is due to the leakage current and the current due to the offset voltage between V
Input impedance is inversely proportional to clock frequency; typical values are for the MCP3550/1 device. V
Characterized by design, but not tested.
Rejection performance depends on internal oscillator accuracy; see Section 4.0 “Device Overview” for more informa-
tion on oscillator and digital filter design. MCP3550/1 device rejection specifications characterized from 49 to 61 Hz.
