AD7841ASZ Data Acquisition - Digital to Analog Converters (DAC)

The AD7841ASZ is a digital to analog converter (DAC) designed for high-speed operation in demanding applications. The device offers the performance required for a wide range of general-purpose applications, ranging from audio and video processing to medical imaging and consumer electronics.

The AD7841ASZ is a single-channel, 10-bit DAC that can operate as either a voltage-output device or current-output device. The converter has a full-scale current capability of 500 µA and a full-scale voltage output of 4.096 volts. The device is available in a small 8-lead SOIC package.

Features:

• Single-channel, 10-bit DAC
• Voltage-output or current-output device
• Full-scale current capability of 500 µA
• Full-scale voltage output of 4.096 volts
• Small 8-lead SOIC package

Applications:

• Audio and video processing
• Medical imaging
• Consumer electronics

Working Principle:

The AD7841ASZ uses a binary-weighted architecture to generate an analog voltage or current output. The device takes an 8-bit digital input and produces an analog voltage or current output that is proportional to the value of the digital input. The device uses a voltage reference (VREF) and a current reference (IREF) to provide a reference for the output voltage or current. The output is then related to the reference by a scaling factor.

The converter operates at a maximum conversion rate of 400 kHz and has no latency, allowing it to be used in time-critical applications. The device also features a power-down mode, which can reduce power consumption by up to 90% when the device is not in use. The device can be used with a wide range of logic families, including both TTL and CMOS, as well as with 3.3V and 5V supplies.

The AD7841ASZ is ideal for use in applications that require high resolution and high speed, such as video and imaging, as well as industrial, medical, and consumer applications.
