A/D CONVERTER CHARACTERISTICS
All typical values are for 25°C ambient temperature and 5 V at pin Vcc. Maximum and minimum specifications are over the
recommended operating conditions. All voltages are referred to the voltage at pin Vss unless otherwise specified. All bits in control
registers are “0” unless otherwise specified.

, 0.1%,
resistor connected between R1 and Vss, and another between R2 and Vss
unless otherwise specified. 400kHz TTL input at SCL unless otherwise specified. SDA pulled to Vcc through an external 2k
Ω
resistor
unless otherwise specified. 2-wire interface in “standby” (see notes 1 and 2 on page 22), unless otherwise specified. WP, A0, A1, and A2
floating unless otherwise specified.
Notes: 1.
“LSB” is defined as V(VRef)/63, “Full Scale” is defined as V(VRef).
Offset
ADC
: For an ideal converter, the first transition of its transfer curve occurs a
amount of deviation between the measured first transition point and the ideal point.
FSError
ADC
: For an ideal converter, the last transition of its transfer curve occurs at
of deviation between the measured last transition point and the ideal point,
after subtracting the Offset from the measured curve.
DNL
ADC
: DNL is defined as the difference between the ideal and the measured code transitions for successive A/D code outputs
expressed in LSBs. The measured transfer curve is adjusted for Offset and Fullscale errors before calculating DNL.
INL
ADC
: The deviation of the measured transfer function of an A/D converter from the ideal transfer function. The INL error is also
defined as the sum of the DNL errors starting from code 00h to the code where the INL measurement is desired. The measured trans-
fer curve is adjusted for Offset and Fullscale errors before calculating INL.
These parameters are periodically sampled and not 100% tested.
