Analog Devices Inc. DAC8212AV/883C Dual 12-Bit Multiplying Digital-to-Analog Converter

The DAC8212AV/883C is a precision dual 12-bit multiplying digital-to-analog converter (DAC) designed and manufactured by Analog Devices Inc., a leader in high-performance analog, mixed-signal, and digital signal processing integrated circuits. This particular model is part of the military-grade product line, which means it adheres to stringent standards for reliability and performance under harsh conditions, making it suitable for aerospace and defense applications.

With its dual-channel configuration, the DAC8212AV/883C provides two independent DACs in a single package, allowing for compact and efficient designs. Each channel has its own 12-bit input register and a multiplying DAC that enables the conversion of digital input signals into precise analog voltages or currents. This feature is particularly useful in applications requiring fine control of analog signals, such as automated test equipment, precision instrumentation, and control systems.

The device operates over a wide supply voltage range, ensuring flexibility in various system designs. It also boasts excellent static performance, with low differential nonlinearity (DNL) and integral nonlinearity (INL), ensuring accurate and stable output. The DAC8212AV/883C's fast settling time and low glitch energy contribute to its high dynamic performance, which is critical in rapidly changing signal environments.

Additional features of the DAC8212AV/883C include a double-buffered interface that allows for simultaneous update of both DACs, a flexible reference input capable of accepting both positive and negative voltages, and a power-on reset circuit that ensures the DAC outputs power up to a known state. The device is packaged in a robust ceramic dual in-line package (CerDIP), providing additional protection against environmental factors.

For engineers and designers working in the defense and aerospace sectors, the DAC8212AV/883C from Analog Devices Inc. offers a reliable and high-performance solution for digital-to-analog conversion needs. Its combination of dual-channel operation, high precision, and military-grade robustness makes it an excellent choice for mission-critical applications where accuracy and durability are paramount.
