GENERAL DESCRIPTION
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.
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.
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.
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.

Description
Positive supply. Nominal value
+5 volts, ± 5%.
Twelve Binary Data Bit inputs. DB11
is the MSB and DB0 is the LSB.
Chip Enable. Active low input.
Active low digital input that clears the
DAC register to zero, setting the DAC
to minimum scale.
Digital ground for input logic.
Analog Ground. Ground reference for
the internal bandgap reference voltage,
the DAC, and the output buffer.
Voltage output from the DAC. Fixed
output voltage range of 0 V to 4.095 V
with 1 mV/LSB. An internal tempera-
ture stabilized reference maintains a
fixed full-scale voltage independent of
time, temperature and power supply
variations.
Nominal 2.5 V reference output volt-
age. This node must be buffered if re-
quired to drive external loads.
No Connection. Leave pin floating.
