Analog Devices AD7247JN Dual 12-Bit DAC

The AD7247JN from Analog Devices Inc. is a high-performance, dual 12-bit digital-to-analog converter (DAC) that offers an exceptional balance of accuracy, speed, and ease of use. Designed with precision applications in mind, this integrated circuit is ideal for a wide range of industrial, communication, and instrumentation systems where reliable digital-to-analog conversion is essential.

This remarkable DAC features two precision 12-bit voltage output DACs on one monolithic chip. Each DAC has its own voltage reference input which can be set independently, allowing for greater flexibility in various applications. The AD7247JN operates from a single +15V supply or dual ±15V supplies, providing designers with versatile power options to suit their specific system requirements.

The AD7247JN boasts a settling time of just 4 microseconds to 1/2 LSB, ensuring quick and accurate updates to the analog outputs. This makes it an excellent choice for closed-loop control systems and other applications that require rapid response times. Additionally, the device is equipped with a power-on reset circuit, which ensures that the DAC outputs power up to zero volts and remain there until a valid write takes place.

Interfacing with microprocessors is made straightforward with the AD7247JN, thanks to its double-buffered interface. This feature allows the input and DAC registers to be updated independently, thereby simplifying the timing and control requirements. The device also supports both parallel and serial input formats, providing additional flexibility for system integration.

Constructed with Analog Devices' advanced, high-performance BiMOS II process, the AD7247JN is packaged in a 24-pin DIP, making it compatible with a wide range of standard sockets and boards. It also features an on-chip, user-selectable output amplifier that can be configured for either a x1 or x2 gain, further enhancing its versatility.

Overall, the AD7247JN is a robust and reliable solution for any system that demands high-quality, dual-channel digital-to-analog conversion. Its combination of speed, precision, and ease of use makes it a top choice for engineers and designers across various industries.
