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.
The op amp output swings from 0 to +4.
095 volts for a one millivolt per bit resolution, and is capable of driving ± 5 mA.
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.
The interface is very simple requiring only a single CE signal.
An asynchronous CLR input sets the output to zero scale.
The DAC8562 is available in two different 20-pin packages, plastic DIP and SOL-20.
Each part is fully specified for operation over –40°C to +85°C, and the full +5 V ± 5% power supply range.
For MIL-STD-883 applications, contact your local ADI sales office for the DAC8562/883 data sheet which specifies operation over the –55°C to +125°C temperature range.
