The MAX551BCUB+T is a 8-bit, micropower digital-to-analog converter (DAC) from Maxim Integrated. It provides 2× the accuracy of conventional single-supply DAC solutions, and 3× increased dynamic range. The device also features programmable current and voltage outputs for a variety of applications. The DAC features a 5V low drift voltage reference, which can be set to a desired operating range.

The MAX551BCUB+T is designed to be used in a wide range of applications, including audio, video, and automotive. It is ideal for nonvolatile products, where the DAC is required to maintain its state without external power. It features low power consumption and low distortion, making it well suited for applications where power efficiency and traditional audio performance are demanded.

The DAC consists of two independent analog converter blocks, one between the current and voltage outputs, and one between the current and voltage inputs. The converters are controlled by a short, 8-bit wide and 2.2 μs wide reference clock input. The device utilizes an asynchronous focus-out programming method to provide wide-ranging, stable current and voltage outputs.

The MAX551BCUB+T offers a highly programmable output current or voltage. The user has the ability to program currents and voltages directly as digital values, or as analog voltages or currents. In addition, the user can select either a 1, 2, or 3 cell bipolar or unipolar output type. The device also offers an adjustable, +/- 1.2% accurate, 0.5V low drift voltage reference.

In addition to providing a highly programmable output voltage or current, the MAX551BCUB+T also offers a low operating current of 0.7mA, a fast settling time of 1mA/μs and a low noise density of 41nV/√Hz. The device also features an integrated voltage output multiplier circuit, and is capable of up to a 5x voltage swing.

The MAX551BCUB+T also benefits from an advanced on-board EMI filter, allowing the device to operate in any environment, even those subjected to heavy EMC requirements. This EMI filter offers improved DC offset, power line filtering and immunity against RFI, making it ideal for automotive, medical and industrial applications.

In summary, the MAX551BCUB+T is a high performance, low power digital-to-analog converter. It offers a wide range of programmable outputs, and benefits from an advanced on-board EMI filter. The device is suitable for a wide range of applications, including automotive, medical and industrial.
