MAX5237EUB+T Datasheet/PDFThe MAX5237EUB+T is a 12-bit digital-to-analog converter (DAC) that is used for data acquisition applications. It features a flexible, power-efficient architecture and high linearity resolution, making it an ideal solution for applications that require both precision and high speed. The device also features an integrated input latch and two voltage references to simplify the design process.
Application Field
The MAX5237EUB+T can be used in data acquisition applications requiring a variety of input formats. It is ideal for applications that require a variable output voltage range, such as control systems, medical instrumentation, industrial process control, and telecommunications systems. It is also well-suited to consumer audio applications because of its low-distortion linearity and wide range of output voltages.
Working Principle
The MAX5237EUB+T works by converting analog signals into digital signals, which are then processed and outputted as an analog voltage. The 12-bit DAC operates on a 0 to 5.0V range for both input and output signals, providing a maximum output resolution of 1.22mV. By changing the values of the input registers, the DAC can be used to output any voltage within the specified range.
The max5237EUB+T contains both a program counter and an accumulator to provide increased speed and accuracy. The accumulation function is used to keep track of the present value of the conversion, which helps improve the linearity of the output. The digital-to-analog conversion is performed on each clock cycle, and the output will be equalized to the input value by the last clock cycle.
The MAX5237EUB+T also contains an integrated output latch and two on-chip reference voltages. The reference voltages can be configured to provide either a full-scale or a mid-scale output, depending on the application. The MAX5237EUB+T also features an active current source output driver and a surge-limited power-on reset circuit.
