CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8582 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
REV. 0
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

PIN CONFIGURATIONS
Description
Voltage outputs from the DACs. Fixed
output voltage range of 0 V to 4.095 V
with 1 mV/LSB. An internal
temperature stabilized reference
maintains a fixed full-scale voltage
independent of time, temperature and
power supply variations.
Analog Ground. Ground reference for
the internal bandgap reference voltage,
the DAC, and the output buffer.
Load DAC register strobes. Transfers
input register data to the DAC registers.
Active low inputs, Level sensitive latch.
May be connected together to double-
buffer load DAC registers.
Digital Input: High presets DAC
registers to half scale (800
clears DAC registers to zero (000
upon RST assertion.
Active low digital input that clears the
DAC register to zero, setting the DAC
to minimum scale when MSB pin = 0,
or half-scale when MSB pin = 1.
Twelve Binary Data Bit Inputs. DB11 is
the MSB and DB0 is the LSB.
Chip Select. Active low input.
Select DAC A = 0 or DAC B = 1.
Positive Supply. Nominal value +5 V, 5%.
Nominal 2.5 V reference output
voltage. This node must be buffered if
required to drive external loads.
