A monolithic 12-bit digitally calibrated D/A converter

“…Up until recently, high-resolution digital-to-analog converters (DACs) are widely used in industrial process control applications such as programmable logic controllers and sensor controllers [1][2][3][4][5][6][7][8][9][10][11][12][13]. In these applications, the DAC is part of a sensor/controller feedback system and used for controlling such devices as motors and cylinders based on the sensors inputs.…”

“…In these applications, the DAC is part of a sensor/controller feedback system and used for controlling such devices as motors and cylinders based on the sensors inputs. Therefore, dynamic key performances indicators such as spurious-free dynamic range (SFDR) and signal-tonoise-and-distortion ratio (SNDR) are not subject to strict requirements; however, high resolution and fast settling time to control the objects accurately and fast are more critical [1,2]. For example, in the application of automatic control equipment, the accuracy of DAC is usually required to be 12 bit~16 bit, and the settling time is required to be 1 μs~100 μs.…”
