Product Summary

The MC14433P is a high-performance, low-power, 3 1/2 digit A/D converter combining both linear CMOS and digital CMOS circuits on a single monolithic IC. The MC14433P is designed to minimize use of external components. With two external resistors and two external capacitors, the system forms a dual-slope A/D converter with automatic zero correction and automatic polarity.

Parametrics

MC14433P absolute maximum ratings: (1)DC supply voltage: -0.5 to +18 V; (2)voltage any pin referenced to VEE: -0.5 to VDD+0.5 V; (3)DC input current per pin: ±10 mA; (4)operating temperature range: -40 to +85 ℃; (5)storage temperature range: -65 to +150 ℃.

Features

MC14433P features: (1)accuracy: ±0.05% of reading ±1 count; (2)two voltage ranges: 1.999 V and 199.9 mV; (3)up to 25 conversions per second; (4)zin>1000 M ohm; (5)auto-polarity and auto-zero; (6)single positive voltage reference; (7)standard B-series CMOS outputs-drives one low power schottky load; (8)use on-chip system clock, or external clock; (9)overrange in auto ranging circuits.
