AD7228KNZ

AD7228KNZ Description

The AD7228KNZ is an 8-bit digital-to-analog converter (DAC) designed for high-performance applications requiring precise analog output. Manufactured by Analog Devices Inc., this IC is part of the Data Acquisition ICs category and is housed in a 24-pin DIP package, making it suitable for through-hole mounting. The AD7228KNZ features eight D/A converters, each capable of converting digital input signals into analog outputs with high accuracy and minimal error.

Key technical specifications include an INL (Integral Non-Linearity) and DNL (Differential Non-Linearity) of ±1 LSB (Least Significant Bit) maximum, ensuring high linearity and precision in the conversion process. The data interface is parallel, allowing for efficient and fast data transfer between the DAC and the controlling microprocessor or microcontroller. The settling time of the AD7228KNZ is 5µs for a 10V step and 7µs for a full-scale step, providing rapid response times suitable for dynamic applications.

The AD7228KNZ operates with a digital supply voltage range of 13.5V to 16.5V, ensuring compatibility with various power supply configurations. It requires an external reference, which allows for flexibility in setting the output voltage range. The moisture sensitivity level (MSL) is 1, indicating that the device is not moisture and-sensitive can be stored indefinitely without special handling.
