The LTC1286CS8#PBF is a micropower successive approximation sampling 12-bit Analog-to-digital Converter (ADC) typically draw only 250μA of supply current when converting and automatically power down to a typical supply current of 1nA whenever they are not performing conversions. On-chip serial ports allow efficient data transfer to a wide range of microprocessors and microcontrollers over three wires. This coupled with micropower consumption, makes remote location possible and facilitates transmitting data through isolation barriers. This circuit can be used in ratiometric applications or with an external reference. The high impedance analog inputs and the ability to operate with reduced spans allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.
