The AD7243 is a complete 12-bit, voltage output, digital-toanalog converter with output amplifier and Zener voltage reference 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 kΩ load. The output voltage ranges with single supply operation are 0 V to +5 V or 0 V to +10 V, while an additional bipolar ±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 complement 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 digital 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 (LC2 MOS), an advanced, mixed technology process. It is packaged in 16-lead DIP and 16-lead SOIC packages.

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
