The AD7245AANZ is a complete 12-bit voltage output Digital-to-analog Converter with output amplifier and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. It is an enhanced version of the industry standard DAC includes operation from 12 to 15V supplies, a ±1/2LSB linearity grade, faster interface times and better full scale and reference variations with VDD. It is microprocessor compatible with high speed data latches and double-buffered interface logic. The AD7245A accepts 12-bit parallel data that is loaded into the input latch on the rising edge of CS or WR. The AD7248A has an 8-bit-wide data bus with data loaded to the input latch in two write operations. For an asynchronous LDAC signal transfers data from the input latch to the DAC latch and updates the analog output. The AD7245A also has a CLR signal on the DAC latch which allows features such as power-on reset to be implemented.
