Analog Output Circuitry

Last Modified: May 14, 2018

The NI ELVIS III provides four analog output channels on the NI ELVIS III Prototyping Board. These channels are controlled independently by the FPGA. Each analog output channel consists of a DAC and an output buffer.

FPGA

The FPGA converts the intended voltage level into digital codes which are then sent to the DAC for digital-to-analog conversion.

Digital-to-Analog Converter

Each analog output channel has a 16-bit digital-to-analog converter (DAC) to convert digital codes to analog voltages.

Output Buffer

The output buffer receives the analog voltage from the DAC and converts it to an output analog signal with a range of ±10 V.
