The AD5766 is a 16-channel, 16-bit, voltage output denseDAC digital-to-analogue converter (DAC).
The DAC generates output voltage ranges from an external 2,5 V reference. Depending on the voltage range selected, the midpoint of the output span can be adjusted, allowing a minimum output voltage as low as −20 V or a maximum output voltage of up to 14 V.
The AD5766 has integrated output buffers that can sink or source up to 20 mA. In conjunction with these buffers, a low-frequency signal can be superimposed onto each DAC output via dedicated dither pins. These pins simplify the system design by reducing the number of external components required for a similar external implementation.
The AD5766 uses a versatile four-wire serial interface that operates at clock rates of up to 50 MHz for write mode, and is compatible with SPI, QSPI, MICROWIRE, and DSP interface standards.
