Notice: Stresses above those listed under “Maximum Rat-
ings” 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
operational listings of this specification is not implied.
Exposure to maximum rating conditions for extended periods
may affect device reliability

ELECTRICAL CHARACTERISTICS
Electrical Specifications: Unless otherwise specified, all parameters apply for TA = -40°C to +85°C, VDD = +5.0V, VSS = 0V,
CHn+ = CHn- = VREF/2, VINCOM = VREF /2. All ppm units use 2*VREF as differential full scale range.

Note
1:
Any input voltage below or greater than this voltage causes leakage current through the ESD diodes at the input pins.
This parameter is ensured by characterization and not 100% tested.
2:
This input impedance is due to 3.2 pF internal input sampling capacitor.
3:
This parameter is ensured by design and not 100% tested.
4:
The total conversion speed includes auto-calibration of offset and gain.
5:
INL is the difference between the endpoints line and the measured code at the center of the quantization band.
6:
Includes all errors from on-board PGA and VREF.
7:
This parameter is ensured by characterization and not 100% tested.
8:
MCP3427 and MCP3428 only.
9:
Addr_Float voltage is applied at address pin.
10: No voltage is applied at address pin (left “floating”).
