The AD7243BRZ is a monolithic 12-bit voltage output digital-to-analog converter (DAC) from Analog Devices, fabricated on LC2MOS technology. It integrates an output amplifier and a factory-trimmed 5 V Zener voltage reference, eliminating the need for external trimming. The device supports single or dual supply operation with analog power ranges of +10.8 V to +16.5 V and -10.8 V to -16.5 V. It features a 3-wire serial interface capable of 300 kHz update rates and includes a daisy-chain capability via the SDO pin. Key performance metrics include a settling time of 10 µs, differential nonlinearity of ±0.9 LSB, and integral nonlinearity of ±0.5 LSB.
Verify the specific grade suffix 'B' corresponds to the industrial temperature range (-40°C to +85°C) as defined in the datasheet specifications. Confirm package type is 16-lead SOIC. Ensure supply voltages remain within the specified limits (+10.8 V to +16.5 V) to maintain guaranteed linearity and accuracy parameters.
Select this component when a complete 12-bit voltage output DAC with integrated reference is required. The B-grade version is suitable for industrial environments operating between -40°C and +85°C. Consider the bipolar ±5 V range only if dual supplies are available. Verify that the 10 µs settling time meets system timing requirements.
The AD7243 belongs to the DACPORT family of CMOS data converters. The BRZ suffix indicates the B-grade temperature rating and RoHS-compliant lead-free packaging in a 16-lead SOIC format. This part replaces older discrete DAC solutions by integrating the reference and amplifier on a single chip.
AD7243ARZ is the A-grade equivalent with the same electrical characteristics but a wider temperature range (-55°C to +125°C). Other variants include AD7243ANZ (DIP package) and AD7243SNZ (extended temperature). Check pin compatibility and thermal ratings when substituting.
