SiChange XC121S101

The XC121S101 is an ultra- low power, small size, single- channel 12- bit analog- to- digital converter with a high speed serial interface. Unlike the conventional practice of specifying performance at a single sample rate only, the XC121S101 is fully specified over a sample rate range of 500 KSPS to 800 KSPS from a single 4 V to 5.25 V supply. The converter is based upon a successive- approximation register architecture with an internal track- and- hold circuit. The XC121S101 is available in a 6- pin SOT- 23 package and has an operating temperature range of - 40℃ to 85℃. The XC121S101 is a drop- in replacement for the ADC121S101 and consumes only half dynamic power of their counterpart.
