GENERAL DESCRIPTION

The DAC8562 is available in two different 20-pin packages,

plastic DIP and SOL-20. Each part is fully specified for opera-

tion over –40°C to +85°C, and the full +5 V ± 5% power supply

range.

The DAC8562 is a complete, parallel input, 12-bit, voltage out-

put 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.

For MIL-STD-883 applications, contact your local ADI sales

office for the DAC8562/883 data sheet which specifies opera-

tion over the –55°C to +125°C temperature range.

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 sup-

ply 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 resolu-

tion, and is capable of driving ±5 mA. Built using low tempera-

ture-coefficient silicon-chrome thin-film resistors, excellent

linearity error over temperature has been achieved as shown be-

low 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 sim-

ple requiring only a single CE signal. An asynchronous CLR in-

put sets the output to zero scale.
