AD7228ABQ

The AD7228ABQ is a precision 8-bit digital-to-analog converter (DAC) from Analog Devices / Maxim Integrated, offering eight independent output channels with a buffered voltage output. It utilizes an R-2R ladder architecture for linear conversion and supports a parallel data interface for fast data transfer. The device requires an external voltage reference and operates over a supply voltage range of 10.8V to 16.5V. It is designed for through-hole mounting in a 24-pin CDIP (Ceramic Dual In-line Package) with a 0.300-inch width, also known as a 24-CERDIP package. The DAC features a settling time of 5µs to 7µs, ensuring responsive analog output updates. With differential outputs available, it is suitable for applications requiring balanced or differential analog signals. The operating temperature range of -40°C to +85°C allows for use in industrial environments. The integral non-linearity (INL) and differential non-linearity (DNL) are specified at ±1 LSB maximum, ensuring monotonic performance. This DAC is suitable for a variety of data acquisition systems, process control, and industrial automation applications where multiple analog outputs are needed.
