Data Acquisition - Digital to Analog Converters (DAC) have a wide range of applications, from audio to industrial control. The AD5663BRMZ-1REEL7 is a 16-bit, binary input DAC and precision monolithic amplifier designed for a variety of applications requiring precision. This DAC is a single channel, 16-bit monolithic DAC distinguished by low glitch energy and the capability of updating to bipolar mode. It converter includes a voltage doubler, eliminating the need for negative power supply and an enhanced on-chip amplifier.

The AD5663BRMZ-1REEL7 boasts a maximum resolution of 16-bits and a minimum full scale output range of 0V to 4.096V. The output update rate is also very fast, with a settling time of a few microseconds. The unit is designed for operation from a single supply voltage ranging from 3.3V to 5.5V, and the output can be offset by up to 1.5V from the reference voltage. It also features low glitch energy and a high power supply rejection ratio.

The AD5663BRMZ-1REEL7 has a typical SNR of -79 dB and is compliant with recomended performance parameters in the EIA RS–232, RS-422 and RS-485 interfaces. In addition, the DAC has a high accuracy, with an integral nonlinearity (INL) of 1LSB, and a high output voltage accuracy over a wide temperature range. The device is also protected against thermal shutdown and current limit protection.

In terms of working principle, the AD5663BRMZ-1REEL7 is a voltage output device that uses a pair of digital inputs to generate an analog output. The internal digital-to-analog converter (DAC) consists of an R-2R ladder network which converts the binary input to a voltage output. This voltage is then amplified by the on-chip amplifier to provide a precision output that is proportional to the DAC’s digital code. The output amplifier has a gain of 2, enables rail-to-rail output swing, is configured for single-supply operation, and can be used for supplying load currents up to 10 mA.

The AD5663BRMZ-1REEL7 is a robust, low-cost and reliable data acquisition-based DAC making it suitable for a range of high-performance and precision applications such as instrumentation, industrial process control, medical devices and audio. Applications where high accuracy and precision is essential, such as data acquisition systems, will also benefit from using this DAC. It is also well suited for applications where wide bandwidth, fast settling time and low output current variations are required.
