The TC14433 is a low-power, high-performance,
monolithic CMOS 3-1/2 digit A/D converter. The
TC14433 combines both analog and digital circuits on
a single IC, thus minimizing the number of external
components.
This dual slope A/D converter provides automatic
polarity and zero correction with the addition of two
external resistors and two capacitors. The full scale
voltage range of this ratiometric IC extends from
199.9 millivolts to 1.999 volts. The TC14433 can
operate over a wide range of power supply voltages,
including batteries and standard 5-volt supplies.

the industry standard TC14433. Rollover, which is the
measurement of identical positive and negative
signals, is specified to have the same reading within
one count for the TC14433A. Power consumption of
the TC14433A is typically 4 mW, approximately one-
half that of the industry standard TC14433.
The TC14433/A is available in 24-Pin PDIP, 24-Pin
SOIC (TC14433 device only), and 28-Pin PLCC
packages.
