AD5380BSTZ-3

Data Acquisition systems, such as laptops or computers, require Digital to Analog Converters (DACs) to display or store information in an analog format. DACs take digital values and turn them into analog signals, which can then be interpreted by other data acquisition devices. The AD5380BSTZ-3, from Analog Devices, is a precision Digital-to-Analog Converter (DAC) that provides exceptional accuracy and reliability. This application note will cover the various features and working principle of the AD5380BSTZ-3 DAC, as well as its various applications and advantages.

The AD5380BSTZ-3 is a low power 8-bit, voltage output DAC with a voltage reference. It features excellent dynamic performance, with a settling time of 10us, and a maximum total different output error of ±2.5mV. This DAC also features low temperature drift, and low noise, with an offset temperature coefficient of on-chip Trim of ±1mV/°C. The AD5380BSTZ-3 is also designed to operate over a wide range of voltages and temperatures. It can operate from -40°C to +125°C with a maximum supply voltage of +5.5V.

The AD5380BSTZ-3 DAC is available in a space saving, TSSOP-16 package. It has a power consumption of only 9mW and has a wide supply range of single-supply operation. Additionally, this device is offered in a customized version with up to 14-bit resolution. It is ESD protected and RoHS compliant.

The working principle of the AD5380BSTZ-3 DAC is based on a DAC ladder composed of an array of 8-bit small capacitors. The capacitors are cascaded in a way that each capacitor divides the DAC output voltage with a value proportional to the digital input. This is multiplexed to generate an analog output voltage that is equivalent to the digital value of the input. The Output Voltage is further divided by a variable resistor that acts as a gain to set the needed range of the output voltage.

The main application field of the AD5380BSTZ-3 is industrial automation and machine control, as well as process control, measurement and monitoring systems. It has a wide variety of applications in virtually any industrial setting. It can be used in systems such as fuel-injection systems, power supplies, motor power supplies, motor control systems, motor and fan speed control systems, servo control systems, and robotic arms. Additionally, the AD5380BSTZ-3 DAC can be used in medical devices such as respirators, ECG machines, and blood pressure monitors, as well as communications systems and audio systems.

The AD5380BSTZ-3 DAC is a powerful, reliable, and highly accurate Digital-to-Analog converter. It has a wide variety of applications in many industrial, medical, and communications systems. Its low power, exceptional accuracy, excellent dynamic performance and low noise make it an ideal choice for a wide range of applications. Its space-saving and RoHS compliant, making it a great choice for applications requiring reliable, high-quality performance.
