IntroductionData Acquisition - Digital to Analog Converters (DAC) are useful components that convert digital signals into analog signals. These devices are often used in fields such as industrial automation, medical equipment, computer peripherals, and instrumentation. The AD7528JNZ is one such DAC device designed to support these applications. This device was designed to meet the needs of a variety of industrial settings and features six 8-bit channels which can be used in different configurations to achieve the desired analog output.This article will cover the application field and working principle of the AD7528JNZ DAC device and provide an overview of its capabilities and current applications. Additionally, this article will discuss the basics of Data Acquisition - Digital to Analog Conversion and provide detailed information about the AD7528JNZ device.Data Acquisition - Digital to Analog ConversionData Acquisition - Digital to Analog Conversion (DA-DAC) is the process of converting digital signals into analog signals for use in applications where analog signals are more beneficial or necessary. Digital and analog signals are different types of electrical signals used to convey information. Digital signals are comprised of binary states (ones and zeroes) while analog signals are continuous signals. In some applications, analog signals are more suitable than digital signals and DA-DAC can be used to bridge this gap between digital and analog signals.AD7528JNZ OverviewThe AD7528JNZ is a 6-channel DAC device designed to meet the needs of a variety of industrial settings. It features a maximum output voltage of 10V and can be used in various configurations to meet a variety of needs. Additionally, the AD7528JNZ provides a low-power shutdown and high-accuracy mode which can be used to achieve the desired accuracy and power savings requirements.The AD7528JNZ features a monotonic resistance-scaled thermocouple input which allows for direct conversion from thermocouple signals to pulses. Additionally, the ADC incorporates a high-order voltage scaling that can be used for direct scaling of temperature signals to volts, thus bypassing the need for a D-A converter in applications that require temperature readings.The AD7528JNZ is also designed to meet various industry standards and can be used in industrial applications such as motor control, HVAC systems, medical equipment, and other applications.AD7528JNZ Working PrincipleThe working principle of the AD7528JNZ is based on the Pulse Width Modulation (PWM) technique. This technique involves digitally controlling the output of a digital signal by varying its duty cycle. When using the PWM technique, the same output can be achieved with much lower power consumption than with conventional digital-to-analog converters (DACs).The AD7528JNZ uses an internal clock to control the output of the device. This clock can be either an external clock or an internal one. The output of the device can be configured to be either bipolar or unipolar. The bipolar configuration allows for output voltages from both a positive and negative voltage, while the unipolar configuration allows for only one output voltage – either positive or negative.The device features an additional output, C/E (conversion/off/enable) which is used to control the operation of the device. When C/E is set to “conversion” the device will convert the digital data into analog data. When set to “off” the device will be in a mode where no data is being converted. When set to “enable” the device will begin converting data.ConclusionThe AD7528JNZ is a 6-channel Digital to Analog Converter device designed for industrial applications. It has been designed to meet various industry standards and its unique features make it well-suited for a variety of applications. The device uses Pulse Width Modulation (PWM) to achieve low-power consumption and provides a monotonic resistance-scaled thermocouple input for direct conversion from thermocouple signals to pulses. Additionally, the ADC incorporates a high-order voltage scaling that can be used for direct scaling of temperature signals to volts. This article has covered the application field and working principle of the AD7528JNZ device and has provided an overview of its capabilities and current applications.
