STMicroelectronics ADC1283 12-Bit SAR Analog-to-Digital Converter
STMicroelectronics ADC1283 12-Bit SAR Analog-to-Digital Converter (ADC) is a low-power, eight-channel pure CMOS 12-bit ADC specified for conversion from 50ksps to 200ksps, tested at 200ksps (3.2MHz clock frequency). The architecture is based on a successive-approximation register (SAR) with an internal track-and-hold cell. The ADC1283 features eight single-ended multiplexed inputs. The output serial data is straight binary and is SPI™ compatible.
The analog power supply operates from 2.7V to 5.5V. The digital power supply operates independently from the analog supply from 2.7V to 5.5V. The power consumption at a 5V nominal supply is as low as 3.2mW. The STMicroelectronics ADC1283 comes in a plastic TSSOP-16 package and can operate from -40°C to +125°C ambient temperature.
