Product Overview

The ADC121C021CIMK/NOPB is a 12-bit monolithic Analog-to-digital Converter (ADC) that operates from a 2.7 to 5.5V supply. The low-power converter is based upon successive approximation register architecture with an internal track-and-hold circuit that can handle input frequencies up to 11MHz. This converter operates from a single supply which also serves as the reference. The device features an I²C-compatible serial interface that operates in all three speed modes, including high speed mode. The alert feature provides an interrupt that is activated when the analog input violates a programmable upper or lower limit value. The device features an automatic conversion mode, which frees up the controller and I²C interface. In this mode, the ADC continuously monitors the analog input for an out-of-range condition and provides an interrupt if the measured voltage goes out-of-range. The automatic power-down feature reduces the power consumption to less than 1µW while not converting.
  • Extended power supply range
  • Up to nine pin-selectable chip addresses
  • Out-of-range alert function
  • Automatic power-down mode while not converting
  • Green product and no Sb/Br
