TC14433/A
3-1/2 Digit, Analog-to-Digital Converter
Features: Description 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. Accuracy: В±0.05% of Reading В±1 Count
Two Voltage Ranges: 1.999V and 199.9 mV
Up to 25 Conversions Per Second
ZIN > 1000M Ohms
Single Positive Voltage Reference
Auto-Polarity and Auto-Zero
Overrange and Underrange Signals Available
Operates in Auto-Ranging Circuits
Uses On-Chip System Clock or External Clock
Wide Supply Range: В±4.5V to В±8V 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. Applications: The TC14433A features improved performance over
the industry standard TC14433. Rollover, which is the …
