16-Bit Digital-to-Analog Converter
The digital to analog converter takes as its input a digital value from the binary inputs and converts the decimal value into an analog voltage between the voltage levels detected on the AGND and VREF analog inputs. If the WR input is Low, the analog voltage is calculated every time an input bit changes. If WR input is High the analog output voltage do not change. Following a change on one or more of the binary inputs, the analog output changes linearly from the old value to the new value over the specified TSW time.
