D/A 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. 510, 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 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
divided by the resistance between R1 or R2 to Vss.
2. Offset
DAC
: The Offset of a DAC is defined as the deviation between the measured and ideal output, when the DAC input is 01h. It is
expressed in LSB.
FSError
DAC
: The Full Scale Error of a DAC is defined as the deviation between the measured and ideal output, when the input is
FFh. It is expressed in LSB. The Offset
DAC
is subtracted from the measured value before calculating FSError
DAC
.
DNL
DAC
: The Differential Non-Linearity of a DAC is defined as the deviation between the measured and ideal incremental change in
the output of the DAC, when the input changes by one code step. It is expressed in LSB. The measured values are adjusted for Off-
set and Full Scale Error before calculating DNL
DAC
.
INL
DAC
: The Integral Non-Linearity of a DAC is defined as the deviation between the measured and ideal transfer curves, after
adjusting the measured transfer curve for Offset and Full Scale Error. It is expressed in LSB.

These parameters are periodically sampled and not 100% tested.
