ADC1283 Description
The ADC1283 is a low-power, eight-channel pure CMOS 12-bit analog-to-digital converter specified for conversion from 50 ksps to 200 ksps, tested at 200 ksps (3.2 MHz clock frequency). The architecture is based on a successive-approximation register with an internal track-and-hold cell.
