MX7847BN Description

The MX7847BN is a high-performance 12-bit digital-to-analog converter (DAC) designed by Analog Devices Inc./Maxim Integrated, a leading manufacturer in the electronics industry. This DAC 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 MX7847BN is designed to provide precise analog output signals from digital inputs, making it an essential component in various electronic systems that require accurate signal conversion.

MX7847BN Features

• 12-Bit Resolution: The MX7847BN offers a 12-bit resolution, providing a high level of precision for analog output signals. This high resolution ensures that the DAC can accurately represent a wide range of digital input values, making it suitable for applications that demand high accuracy.
• Two DACs: The MX7847BN features two independent DACs, allowing for simultaneous control of two different analog signals. This dual-DAC configuration is ideal for applications that require multiple output signals, such as audio processing or multi-channel control systems.
• Parallel Data Interface: The DAC employs a parallel data interface, which allows for fast and efficient data transfer between the DAC and the controlling microprocessor or microcontroller. This interface ensures that the DAC can quickly respond to changes in the digital input, providing real-time analog output.
• Wide Supply Voltage Range: The MX7847BN operates with a wide supply voltage range of ±11.4V to ±16.5V for both analog and digital supplies. This wide range makes the DAC versatile and compatible with various power supply configurations, reducing the need for additional voltage regulation components.
• Low Integral and Differential Non-Linearity (INL/DNL): The DAC exhibits low INL and DNL errors of ±0.5 LSB (max) and ±1 LSB (max), respectively. These low error values ensure that the DAC's output is highly linear and accurate, minimizing distortion and improving overall system performance.
• Fast Settling Time: With a typical settling time of 4µs, the MX7847BN can quickly stabilize its output to the desired analog level. This fast settling time is crucial for applications that require rapid response times, such as real-time control systems or high-speed data acquisition.
• External Reference: The MX7847BN uses an external reference voltage, allowing users to select a high-quality reference source to further enhance the accuracy and stability of the DAC's output.
• Moisture Sensitivity Level (MSL) 1: The DAC has an MSL rating of 1, indicating that it is not sensitive to moisture and can be stored or operated in a wide range of environmental conditions without the need for special handling.
