DC CHARACTERISTICS (CONTINUED)
Electrical Specifications: Unless otherwise indicated, all parameters apply at -40°C
≤ TA ≤ +85°C, VDD = 2.7V or 5.0V.
VREF = 2.5V. VIN+ = VIN- = VCM = VREF/2. All ppm units use 2*VREF as full scale range. Unless otherwise noted, specification
applies to entire MCP3550/1/3 family.

Conditions
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 VIN+ and VIN-.
4:
Input impedance is inversely proportional to clock frequency; typical values are for the MCP3550/1 device. VREF =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. MCP3550/1 device rejection specifications characterized from 49 to 61 Hz.
