ADS7818P

The ADS7818P is designed as a 12-bit sampling analog-to-digital converter (ADC) complete with sample/hold, internal 2.5V reference, and synchronous serial interface. Typical power dissipation is 11mW at a 500kHz throughput rate.

It has nine features. (1)500kHz throughput rate. (2)2.5V internal reference. (3)Low power 11mW. (4)Single supply +5V operation. (5)Differential input. (6)Srial interface. (7)Guaranteed no missing codes. (8)8-pin mini-DIP and MSOP. (9)Unipolar input range. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its Vcc to GND would be from -0.3V to +6V. (2)Its analog input would be from -0.3V to Vcc+0.3V. (3)Its logic input would be from -0.3V to Vcc+0.3V. (4)Its power dissipation would be 325mW. (5)Its maximum junction temperature would be 150°C. (6)Its storage temperature would be from -65°C to 150°C. (7)Its lead temperature soldering 10s would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics are concluded into several points as follow. (1)Its resolution would be typ 12bits. (2)Its full-scale input span would be min 0V and max 5V. (3)Its absolute input range would be min -0.2V and max Vcc+0.2V for +IN and would be min -0.2V and max +0.2V for -IN. (4)Its capacitance would be typ 15pF. (5)Its leakage current would be typ 1uA. (6)Its logic input high voltage would be min 3.0V and max Vcc+0.3V. (7)Its input low voltage would be min -0.3V and max 0.8V. (8)Its output voltage high would be min 3.5V. (9)Its output voltage low would be max 0.4V. (10)Its Vcc would be min 4.75V and max 5.25V. (11)Its quiescent current would be typ 2.2mA. (12)Its power dissipation would be typ 11mW and max 20mW.
