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. The ADC1283 features 8 single-ended

multiplexed inputs. The output serial data is straight binary and is SPI™ compatible.

The analog power supply operates from 2.7 V to 5.5 V. The digital power supply

operates independently from analog supply from 2.7 V to 5.5 V. The power

consumption at 5 V nominal supply is as low as 3.2 mW. The ADC1283 comes

in a plastic TSSOP-16 package and can operate from -40 °C to +125 °C ambient

temperature.
