The AD8802ARZ is a highly versatile digital-to-analog converter (DAC) manufactured by Analog Devices Inc., designed for precision calibration of analog systems directly from digital sources. This 12-channel, 8-bit TrimDAC features a compact design, making it an ideal choice for applications where space is at a premium.

Key Features

• 12 Independent DAC Channels: Each channel can be programmed with its own 8-bit digital code, which provides a corresponding analog voltage output.
• Single 5V Supply Operation: Designed to operate from a single 5V power supply, simplifying power management in complex systems.
• Serial Data Input: The device accepts serial input data, which minimizes the number of required I/O lines for DAC control.
• Power Shutdown Capability: Features a power shutdown mode that reduces current consumption to 4 µA max, significantly saving power when the DAC is not in active use.
• Flexible Reference Inputs: Each DAC has its own reference input, allowing for a wide range of output voltage spans.

Applications

The AD8802ARZ is suitable for a variety of applications where precise digital control of analog parameters is needed, including:

• Automatic Test Equipment (ATE)
• Industrial Process Controls
• Data Acquisition Systems
• Instrumentation
• Programmable Amplifiers and Attenuators

Technical Specifications

Overall, the AD8802ARZ by Analog Devices Inc. is a robust and reliable DAC solution for designers looking to integrate precise analog control into their digital systems. Its multi-channel capability and low power consumption make it an efficient and effective choice for a wide range of applications.
