Datasheet Analog Devices DAC8562 — Ficha de datos

a +5 Volt, Parallel Input
Complete 12-Bit DAC
DAC8562 FEATURES
Complete 12-Bit DAC
No External Components
Single +5 Volt Operation
1 mV/Bit with 4.095 V Full Scale
True Voltage Output, 65 mA Drive
Very Low Power –3 mW FUNCTIONAL BLOCK DIAGRAM DAC-8562 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 В± 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. VOUT 12

12 DGND CE DATA CLR 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.
