ADC12441 Dynamically-Tested Self-Calibrating 12-Bit
Plus Sign A/D Converter with Sample-and-Hold
General Description
The ADC12441 is a CMOS 12-bit plus sign successive ap-
proximation analog-to-digital converter whose dynamic
specifications (S/N, THD, etc.) are tested and guaranteed.
On request, the ADC12441 goes through a self-calibration
cycle that adjusts positive linearity and full-scale errors to
less than
g
(/2
LSB each and zero error to less than
g
1 LSB. The ADC12441 also has the ability to go through
an Auto-Zero cycle that corrects the zero error during every
conversion.
The analog input to the ADC12441 is tracked and held by
the internal circuitry, and therefore does not require an ex-
ternal sample-and-hold. A unipolar analog input voltage
range (0V to
a
5V) or a bipolar range (
b
5V to
a
5V) can be
accommodated with
g
5V supplies.
The 13-bit word on the outputs of the ADC12441 gives a 2’s
complement representation of negative numbers. The digi-
tal inputs and outputs are compatible with TTL or CMOS
logic levels.
