Digital-to-Analog Converters (DACs) are used to convert digital signals into analog signals. The AD7528KPZ is a high resolution, low noise, low power, single-channel DAC designed for multi-channel, industrial, automotive and consumer applications. This device offers resolution up to 8 bits and temperature drift as low as 6 ppm/ºC.

The AD7528KPZ is a monolithic integrated circuit (IC) that utilizes a switched capacitor DAC architecture. This type of DAC is characterized by the use of digital data to control a series of electronic switches that disconnect and connect capacitors in the DAC circuit. As the digital data increase or decrease in number, the resulting output voltage of the DAC changes correspondingly. This process of converting digital data into analog signals is known as delta-sigma conversion.

The AD7528KPZ operates over a wide supply voltage range (2.7V to 15V) and offers excellent power supply noise rejection. It also has an on-chip amplifier and a small (typically 0.3uVpp) programmable output filter. The AD7528KPZ has full 8-bit resolution, very low distortion (typically 0.01%) and low total harmonic distortion (THD).

The AD7528KPZ is designed to interface with a variety of control and data acquisition systems such as microcontrollers, sensor interfaces, and PC-based systems. It is capable of producing linear and accurate analog voltages, which is required in some motor control and multimedia applications. The low power usage of this DAC makes it suitable for battery-powered and portable systems.

This device also has an on-board deglitcher circuit, which helps eliminate noisy transitions between digital words. In addition, it has an internal voltage reference which allows for accurate analog conversion even in noisy and power-disturbed environments. The AD7528KPZ also has an integrated write protect feature that prevents unauthorized data writing.

The AD7528KPZ is an excellent choice for applications that require multiple data channels such as industrial process control, instrumentation, automotive systems, and consumer audio/video products. The low power usage and very low distortion makes it an ideal solution for battery-powered or portable systems. It also has excellent power supply noise rejection and robust output filter characteristics, making it a reliable and cost-effective choice.
