Evaluation Boards - Expansion Boards, Daughter Cards

The MAX5318PMB# is a comprehensive evaluation board that facilitates evaluation of the MAX5318 single-channel, low-power, 10ppm 16-bit, low-voltage, buffered voltage-output digital-to-analog converter (DAC). This board has been designed to get a quicker evaluation of the MAX5318’s features and functions, including its dual-supply operation, small size, low power, and low output noise. The users can also take advantage of the features in the MAX5318, such as the low glitch energy, wide temperature range and low cost, through this evaluation board.

Application Field

The MAX5318PMB# can be used in many different applications. These include automotive, data measurement, test and measurement, medical, consumer, industrial, communication, computing, audio, and video. It can be used in any application where a low-power, low-voltage, low-noise, buffered, and fast-settling DAC is required. For example, the board can be used in automotive applications like engine control, navigation systems, anti-lock braking systems, and audio systems. In data measurement applications, the board can be used for low-power industrial control systems, or for fast-settling systems with low latency.

Working Principle

The MAX5318PMB# utilizes the MAX5318 low-power, low-noise, buffered DAC. This DAC provides a low-power alternative to the traditional DAC architectures, offering both low-power and low-voltage operation. A reference input voltage at the Vref pin sets the full-scale voltage of the output, which is available at the high impedance output buffer connected to OUT pin. The MAX5318HPBI drives its output directly from the device, accessing the low-power and low-voltage features offered by the MAX5318. The board includes the important features of the MAX5318, including low-voltage and low-power operation, wide output voltage range, fast settling time, low output noise, and low integrated circuit (IC) power consumption. The MAX5318PMB# is capable of driving a load of up to 500µA.

The board has a 3.3V logic supply, with a 5V analog reference volt supply, mask select pins, and a 2x20 pin header, which simplifies the evaluation and user debug of the board. It also features the EVAL1 and EVAL2 headers, which are designed to connect to a logic analyzer or oscilloscope for digital interface debugging. The board is also capable of providing supply voltages up to 30V, enabling the evaluation of the MAX5318 with high supply voltages.

The board also includes the integrated calibration and offset/gain adjustment features of the MAX5318. These features enable the user to reduce the output noise to under 0.25LSB. The board also includes two low-noise voltage regulators, an analog ground plane, and the OVP (overvoltage protection) feature. This feature helps to protect the MAX5318 from overvoltage conditions, preventing the board from damage in the event of an overvoltage condition.

Overall, the MAX5318PMB# is an ideal tool to evaluate and debug the low-power, low-voltage, low-noise, buffered DAC. This board provides the necessary features and functions for evaluating the unique features of the MAX5318, including its low-power, low-voltage, low-noise, and fast-settling features. With its integrated calibration and offset/gain adjustment features, the user can achieve a low output noise level and realize the full performance of the MAX5318.
