Product data sheet
[1]
Inputs must be connected to V
connected to pins AGND or VREF.
In order to prevent excessive ground and supply noise and to minimize crosstalk of the
digital-to-analog signal paths the printed-circuit board layout must be designed very
carefully. Noisy digital circuits and ground loops must be avoided on the supply lines
common to the PCA9691 device. Decoupling capacitors (> 10 μF) are recommended for
power supply and reference voltage inputs.
During data transfer the first bit written out is the MSB and the last bit is the LSB.

The linearity error is assured if the internal frequency is changed by setting bit 7 and bit 3 of the control byte
to logic 1 (see
