Digital to Analog Converters (DAC)

Digital-to-Analog Converter (DAC) ICs transform digital binary codes into proportional analog voltage or current signals, enabling microprocessors, DSPs, and FPGAs to reconstruct analog waveforms, adjust bias voltages, control analog actuators, and generate complex radio signals. DACs are critical components in audio systems, industrial process controllers, precision motor drives, and telecommunication transmitters.

DAC architectures include R-2R ladder networks for precise, low-noise voltage outputs, and current-steering DACs for high-speed, high-frequency signal generation. Key selection parameters span resolution (bits), settling time (measured in nanoseconds or microseconds), update rate (SPS), output interface (SPI, I2C, parallel, or JESD204B), integral non-linearity (INL), and differential non-linearity (DNL). High-precision DACs often include integrated low-drift voltage references and output buffer amplifiers.
