Product Details
The AD5766/AD5767 are 16-channel, 16-bit/12-bit, voltage output denseDAC® digital-to-analog converters (DACs).
The DACs generate 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. Each of the 16 channels can be monitored with an integrated output voltage multiplexer.
The AD5766/AD5767 have 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 dedicated dither pins simplify the system design by reducing the number of external components required for a similar external implementation, like operational amplifiers or resistors. The reduction of external components makes the AD5766/AD5767 suitable for indium phosphide Mach Zehnder modulator (InP MZM) biasing applications.
The devices incorporate a power-on reset (POR) circuit that ensures that the DAC outputs are clamped to ground on power up and remain at this level until the output range of the DAC is configured. The outputs of all DACs are updated through register configuration, with the added functionality of user-selectable DAC channels to be simultaneously updated.
The AD5766/AD5767 use a versatile 4-wire serial interface that operates at clock rates of up to 50 MHz for write mode and is compatible with serial peripheral interface (SPI), QSPI™, MICROWIRE™, and DSP interface standards. The AD5766/ AD5767 also contain a VLOGIC pin intended for 1.8 V/3.3 V/5 V logic.
The AD5766/AD5767 are available in a 4 mm × 4 mm WLCSP package and a 40-lead LFCSP package. The AD5766/AD5767 operate at a temperature range of −40°C to +105°C.

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
