DESCRIPTION
ADC150 is a high performance programmable 24-
bit integrating A/D converter based on a patented
architecture. The integration time and resolution
along with the power line cycle selection can be
easily programmed through the Mode Control
Byte.
ADC150 offers 2 ppm max. linearity error and
1 ppm/°C max. scale factor error over the military temperature range. It also has excellent offset stability at
2 ppm max. which the user can auto zero if desired.
ADC150's compatibility with popular microcomputer buses increases its ease of application in smart
systems. An on-board microprocessor controls all internal functions of the ADC150. Thaler designers
have minimized external connections to greatly reduce the problem often encountered when applying
ADC's.
Operating from ±15VDC and a +5VDC power supply, ADC150 is packaged in a hermetically sealed 40-pin
ceramic DIP package. Precision test equipment, scientific and medical instruments, and data acquisition
systems are primary application areas for the unusually high resolution and accuracy of this ADC.
