Data Acquisition – Digital to Analog Converters (DAC) are fundamental components required in every application that involves controlling and monitoring processes. This article examines the application field and working principle of the AD7537KRZ Digital to Analog Converter (DAC).

The AD7537KRZ is a 10-Bit Digital to Analog Converter (DAC) that is composed of R-2R ladders and a fast output amplifier. It is capable of producing monotonically increasing digital-to-analog output, relative to a reference voltage or accuracy of ±0.1% (25°C). The device has an operating temperature range of -40°C to +85°C and is housed in a 20-pin LCC package with a 3.50 mm lead spacing.

The AD7537KRZ has a wide range of applications, which includes telecommunications, industrial and medical equipment, motor control, and audio. Telecom applications include analog output for line control; Industrial and medical equipment applications include speed control for printers, copiers, motor and motor control, position control for stepper motor, measurement and control for test equipment; Audio applications include volume control for sound cards and audio systems.

The operation of the AD7537KRZ can be divided into two parts: Digital to analog conversion and output conversion. The digital input data is written to the device through the SDA pin. The device then converts the digital code into a voltage (or current) in accordance with the digital/analog output data relationship table. Then, the on-chip output amplifier amplifies the analog output signal to generate a stable output point.

The full-scale voltage of the AD7537KRZ is controlled by the external reference voltage, which is applied to the reference input (REF). The reference voltage determines the linearity and accuracy of the device, with the typical value of 5V. The output voltage range can be adjusted by the control resistor C3 connected between the OPT1 and COM1/COM2 pins. The control resistor can also lower the device\'s power consumption.

Additionally, the device is provided with an on-chip low pass filter (LPF) that passes low-frequency signals and reduces high-frequency noise. The filter can be disabled by setting the appropriate bits in the control register. The AD7537KRZ also has a low power shutdown feature that puts the device into low-power consumption mode with a few microamps of consumption when the device is not in use.

In conclusion, the AD7537KRZ Digital to Analog Converter (DAC) is a versatile device that is designed for a wide range of applications including telecommunications, industrial and medical equipment, motor control and audio. It is composed of R-2R ladders and a fast output amplifier which produces monotonically increasing digital-to-analog output with a reference voltage or accuracy of ±0.1%. It also has a variety of features such as a low pass filter and a low power shutdown feature.
