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 ADS1015 is a high precision, low-power, 12-bit, I2C compatible, analog-to-digital converter (ADC). The ADS1015 includes a low-drift voltage reference and an oscillator.
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.
The AD7791 is a low-power, low-noise, 24-bit sigma-delta analog-to-digital converter (ADC) from Analog Devices. It's commonly used in precision measurement applications due to its high resolution and low noise characteristics.
