MC14433

The MC14433 is designed as 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. MC14433 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.

MC14433 has many features. The first oe is its accuracy would be ±0.05% of reading ± 1 count. The second one is two voltage range which would be 1.999V and 199.9mV. The third one is up to 25 conversions per second. The fourth one is Zin would be larger than 1000Mohm. The fifth one is auto-polarity and auto-zero. The sixth one is single positive voltage reference. The seventh one is uses on-chip system clock, or ecternal clock. The eighth one is wide supply range. The ninth one is overange and underrange signals available. The tenth one is operates in auto ranging circuits. And so on. That are the main features.

Some absolute maximum ratings of MC14433 have been concluded into several points as follow. The first one is about its DC supply voltage which would be from -0.5V to +18V. The second one is about its voltage, any pin, referenced to Vee which would be from -0.5V to Vdd+0.5V. The third one is about its DC input current, per pin which would be ±10mA. The fourth one is about its operating temperature range which would be from -40°C to +85°C. The fifth one is about its storage temperature range which would be from -65°C to +150°C. The sixth one is about its recommended DC supply voltage which would be +5.0V to +8.0V for Vdd to analog ground and would be -2.8V to -8V for Vee to analog ground. The seventh one is about its clock frequency whihc would be from 32KHz to 400KHz. The eighth one is about its zero offset correction capacitor which would be 0.1 ±20% uF. And so on.
