GENERAL DESCRIPTION
The AD7243 is a complete 12-bit, voltage output, digital-to-
analog converter with output amplifier and Zener voltage refer-
ence on a monolithic CMOS chip. No external trims are
required to achieve full specified performance.
The output amplifier is capable of developing +10 V across a
2 k
load. The output voltage ranges with single supply opera-
tion are 0 V to +5 V or 0 V to +10 V, while an additional bipo-
lar
±5 V output range is available with dual supplies. The ranges
are selected using the internal gain resistor.
The data format is natural binary in both unipolar ranges, while
either offset binary or two’s complement format may be selected
in the bipolar range. A
CLR function is provided which sets the
output to 0 V in both unipolar ranges and in the two’s comple-
ment bipolar range, while with offset binary data format, the
output is set to –REFIN. This function is useful as a power-on
reset as it allows the output to be set to a known voltage level.
The AD7243 features a fast versatile serial interface which
allows easy connection to both microcomputers and 16-bit digi-
tal signal processors with serial ports. The serial data may be
applied at rates up to 5 MHz allowing a DAC update rate of
300 kHz. A serial data output capability is also provided which
allows daisy chaining in multi-DAC systems. This feature allows
any number of DACs to be used in a system with a simple
4-wire interface. All DACs may be updated simultaneously
using
LDAC.
The AD7243 is fabricated on Linear Compatible CMOS
(LC2MOS), an advanced, mixed technology process. It is pack-
aged in 16-lead DIP and 16-lead SOIC packages.
PRODUCT HIGHLIGHTS
1. Complete 12-Bit DACPORT
The AD7243 is a complete, voltage output, 12-bit DAC on
a single chip. The single chip design is inherently more
reliable than multichip designs.
2. Single or Dual Supply Operation.
3. Minimum 3-wire interface to most DSP processors.
4. DAC Update Rate–300 kHz.
5. Serial Data Output allows easy daisy-chaining in multiple
DAC systems.
