Analog Devices rolled out a single-chip, universal output digital-to-analog converter (DAC) which combines a 16-bit data converter, ±2 ppm/°C 2,5 V reference, output buffer and gain scaling function on-chip.
The innovative feature set of the AD5761R removes the need for external components, including gain setting precision resisters and amplifiers. In data acquisition and actuator control applications, this quickens and simplifies system design, enabling both unipolar and bipolar operation, through a software register update.
The company also released two dual DC-DC regulators that power the new DAC with two independently regulated positive and negative rails for power sensitive applications. This two-chip solution enables users to generate bipolar 10 V outputs from only a single, low-voltage positive supply rail.
The AD5761R’s 3 x 3 mm LFCSP standard package is ideal for designs within shrinking form factors, such as actuator control. The total unadjusted error specification of ±0,15% FSR max is a true error including all on-chip circuitry and reference. This enables more accurate end systems and eliminates multiple system calibration routines in industrial environments.
For a lower-cost, less accurate option within the same series, a pin compatible 12-bit version and non-reference options are also available.
