The DAC8562FSZ is a complete parallel input 12-bit voltage output Digital-to-analog Converter (DAC) designed to operate from a single 5V supply. Built using a CBCMOS process, this monolithic DAC offers the user ease-of-use in 5V only systems. Included on the chip, in addition to the DAC, is a rail-to-rail amplifier, latch and reference. The reference (REFOUT) is trimmed to 2.5V and the on-chip amplifier gains up the DAC output to 4.095V full scale. The DAC8562 is coded straight binary. The op amp output swings from 0 to 4.095V for a 1-mV-per-bit resolution and is capable of driving ±5mA. Built using low temperature-coefficient silicon-chrome thin-film resistors, excellent linearity error over temperature has been achieved. Digital interface is parallel and high speed to interface to the fastest processors without waits states. The interface is very simple requiring only a single CE signal. An asynchronous CLR input sets the output to zero scale.
