STMicroelectronics' ADC120 is a low-power, eight-channel pure CMOS 12-bit analog-to-digital converter specified for conversion from 50 ksps to 1 Msps, tested at 1 Msps. The architecture is based on a successive-approximation register with an internal track-and-hold cell. The ADC120 features eight single-ended multiplexed inputs. The output serial data is straight binary and is SPI™ compatible. The analog and digital power supplies operate from 2.7 V to 3.6 V. The power consumption at 3.3 V nominal supply is as low as 6.6 mW. The ADC120 comes with plastic TSSOP-16 and can operate from -40°C to +125°C ambient temperature.
