DAC8562FSZ

DAC8562 is a complete, parallel input, 12bit, voltage output DAC designed to operate from a single +5 volt supply. Built using a CBCMOS process, these monolithic DACs offer the user low cost, and ease-of-use in +5 volt 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 2.5 volts, and the on-chip amplifier gains up the DAC output to 4.095 volts full scale. The user needs only supply a +5 volt supply. The DAC8562 is coded straight binary. Built using low temperature-coefficient silicon-chrome thin-film resistors, excellent linearity error over temperature has been achieved as shown below in the linearity error versus digital input code plot. Digital interface is parallel and high speed to interface to the fastest processors without wait states. Application includes digitally controlled calibration, servo controls, process control, equipment, PC peripherals.
