AD7225KN

AD7225KN Description

The AD7225KN is an 8-bit digital-to-analog converter (DAC) designed by Analog Devices Inc., a leading manufacturer in the electronics industry. This DAC is part of the Data Acquisition ICs category and is housed in a through-hole package, specifically a 24-pin DIP (Dual In-line Package). The AD7225KN features a parallel data interface, allowing for efficient and straightforward integration into various electronic systems. It operates with a digital supply voltage ranging from 14.25V to 15.75V, ensuring compatibility with a wide range of power sources.

The AD7225KN is known for its high performance and precision, with a maximum INL (Integral Non-Linearity) and DNL (Differential Non-Linearity) of ±1 LSB (Least Significant Bit). This level of accuracy makes it suitable for applications requiring precise analog signal generation. The settling time of 4µs ensures rapid response, enabling the DAC to quickly stabilize its output voltage after a digital input change. The AD7225KN also supports an external reference, providing flexibility in setting the output voltage range.

Despite its obsolescence, the AD7225KN remains a reliable choice for many applications due to its robust design and performance characteristics. It is packaged in a tube, which is ideal for bulk handling and storage. The moisture sensitivity level (MSL) of 1 (Unlimited) indicates that the device is not sensitive to moisture, making it suitable for a variety of environmental conditions.
