1 MSPS ， 8通道，软件可选的真双极性输入， 12位加符号位ADC 1 MSPS, 8-Channel, Software-Selectable, True Bipolar Input, 12-Bit Plus Sign ADC
GENERAL DESCRIPTION
The 1 is an 8-channel, 12-bit plus sign successive approximation ADC designed on the iCMOS™ industrial CMOS process. iCMOS is a process combining high voltage CMOS and low voltage CMOS. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no previous generation of high voltage parts could achieve. Unlike analog ICs using conventional CMOS processes, iCMOS components can accept bipolar input signals while providing increased performance, dramatically reduced power consumption, and reduced package size.
