The MIC5205 is an ultra-small, highly efficient linear voltage regulator available in both adjustable and fixed output voltage variants. This small IC offers ultra-low-noise output, very low dropout voltage and very low ground current.
The MCP4922 is a 12-bit, high accuracy, low noise performance, buffered voltage output Digital-to-Analog Converter (DAC). This is an SPI-compatible Serial Peripheral Interface device with a 2.7V to 5.5V supply.
The ADC0831 is an 8-bit analog-to-digital converter (ADC). It uses the successive approximation method for conversion. The ADC0831 has a serial input/output (I/O) interface and configurable input multiplexers that allow for up to 8 input channels to be selected.
