12-Bit Sampling A/D Converter Conserves Power
This application note uses a timer IC (ICL7555), CMOS logic and discrete transistors to automatically control the conversion the MAX190 12-bit SAR analog-to-digital converter (ADC). The delay between conversions can be programed using a resistor. Logic ci
16-bit ADC provides 19-bit resolution
Many data-acquisition systems require both high accuracy and a fast acquisition rate. These attributes allow the system to detect small data signals and to group more sensor channels into the same system.
555 Timer as an A/D converter
I had a Basic Stamp project that needed to measure a nominal 12 volt battery, and I wanted a simple solution. This is the simplest I could come up with.
A Tamper-resistant Watt-hour Energy Meter Based On The Ad7751 And Two Current Sensors
This application note describes a low-cost, high-accuracy watt-hour meter based on the AD7751.
A/D Converters Easily Interface with 70 Series Microprocessors
This application note describes techniques for interfacing parallel I/O and serial I/O 8-bit A/D converters to the INS8070 series of microprocessors. A detailed hardware and software interface example is provided for each type of A/D.
The A/D Easily Allows Many Unusual Applications
Two design features of the ADC0801 series of A/D converters provide for easy solutions to many system design problems.
