The AD5339BRMZ-REEL7 is a Quad-Channel, Low Power, 11-Bit Digital-to-Analog Converter (DAC) that belongs to the Data Acquisition - Digital to Analog Converters (DAC) family. It features low power consumption, four independent DAC output channels operating from ±2.5 V to 3.3 V/5.0 V/2.7 V voltage references. The device is designed for low-voltage, low-power SPI and I2C control. The DACs have 11-bit resolution, with three-state reference inputs for flexibility in system design.

Applications for the AD5339BRMZ-REEL7 include motion control applications such as servo motors, brushless DC (BLDC) motors, robotics, proportional valves and current loop control, medical instrumentation, test and measurement, such as stimulus generation, waveform generation, transimpedance amplifiers, and push-pull DACs. The AD5339BRMZ-REEL7 also has a wide variety of other applications such as industrial, automotive, and consumer markets.

The AD5339BRMZ-REEL7 working principle is based on the use of a Latchable current-to-voltage converter, which has been designed to provide accurate and fast conversion from digital inputs to analog outputs. The converter is capable of converting 11-bit binary encoded digital values into corresponding output currents. The sum of these output currents is then converted into a voltage, which is proportional to the input digital value.

The AD5339BRMZ-REEL7 has an integrated current source and a voltage-to-current conversion output stage, so that it can drive up to four separate analog outputs. The outputs are available individually or as a single summed output. The outputs can be driven from a voltage reference as low as 0.2 V, up to the supply voltage levels. All outputs are configured independently and can be buffered, allowing for multiple output voltage ranges or gains.

The AD5339BRMZ-REEL7 features serial I2C or SPI interface for programming and control. The serial interface can be used to program the DACs for voltage references and output gains. The device also features two logic select pins, one for selecting the serial interface and one for selecting the input and output voltage reference.

The AD5339BRMZ-REEL7 is an ideal solution for applications in power management, signal conversion and conditioning, where low power consumption and precise operation are required. The device is well suited for applications in the industrial, automotive and consumer markets, and is available in the industry-standard 16-pin TSSOP and SOIC packages.
