ADC120 Datasheet 8-channel, 50 ksps to 1 Msps, 12-bit A/D converter TSSOP-16 Maturity status link ADC120 Device summary Order code ADC120IPT Temperature range -40 °C to +125 °C Package TSSOP-16 Marking ADC120I Features 50 ksps to 1 Msps conversion rate 8-to-1-channel input MUX 3.3 V operating supply Pure CMOS Very low consumption SPI, serial digital output Power-down function Applications Shunt resistor detector Analog multiplexing and conversion Telemetry Description 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 trackand-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, and can operates from -40 °C to +125 °C ambient temperature.
