8-Channel, 50 ksps to 1 Msps, 12-Bit A/D Converter


  • 50 kSPS to 1 MSPS Conversion Rate
  • 8-to-1-Channel Input MUX
  • 3.3 V Operating Supply with Very Low Consumption
  • SPI, Serial Digital Output

The 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 8 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 plastic TSSOP-16 package and can operate from -40 °C to +125 °C.
