# ADC Bit Rates and Resolution

## ADC Pi, ADC Differential Pi and ADC-DAC Boards Bit Rate and Resolution

The table below shows the various bit rates and the resolution in millivolts which our ADC boards can sample.

The ADC Pi, ADC Pi Plus and ADC Pi Zero can sample at 17-bit, 15-bit, 13-bit and 11-bit modes.

The ADC Differential Pi and Delta Sigma Pi can sample in 18-bit, 16-bit, 14-bit and 12-bit in differential mode, and the single-ended mode is the same as the ADC PI boards.

The ADC DAC Pi and ADC DAC Pi Zero sample at 12-bit resolution.
