ADS7834P

The ADS7834P is designed as a 12-bit, sampling analog-to-digital converter (ADC) complete with sample-and-hold (S/H), 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)2.5 internal reference. (3)Low power 11mW. (4)Single supply +5V operation. (5)differential input. (6)Serial interface. (7)Guaranteed no missing codes. (8)8-pin mini-DIP and MSOP. (9)0V to Vref 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 inputs to GND would be from -0.3V to Vcc+0.3V. (3)Its digital inputs to GND 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 operating temperature range would be from -40°C to +85°C. (7)Its storage temperature range would be from -65°C to 150°C. (8)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 Vref. (3)Its absolute input range would be min -0.2V and max Vref+0.2V for +IN and would be miun -0.2V and max +0.2V for -IN. (4)Its capacitance would be typ 25pF. (5)Its leakage current would be typ 1uA. (6)Its logic input voltage high would be min 3.0V and max Vcc+0.3V. (7)Its input voltage low 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. And so on.
