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.

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.

PRODUCT HIGHLIGHTS

1. Complete 12-Bit DACPORT^®

The output amplifier is capable of developing +10 V across a

2 kΩ 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 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.

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.

5. Serial Data Output allows easy daisy-chaining in multiple

DAC systems.

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.
