The MAX5383EUT+T is a digital-to-analog converter (DAC) used in data acquisition applications, allowing digital signals to be transformed into analog signals. Unlike traditional DACs, the MAX5383EUT+T is designed to drive moderately high current analog outputs, allowing it to be used in more demanding applications.

The device can achieve an accuracy of 12 bits and a resolution of 13 to 16 bits when operating at the rated analog output of ±4.096 V (0.31 V/lsb). The output current (IOUT) range is up to 3.2 mA and the maximum output voltage swing is ±4.048 V, which is either self-calibrating or user programmable.

The user interface for the device includes three externally accessible buttons for programming the device. It also includes an optional SPI interface for programming and control of the device. A wide range of features can be programmed, providing significant flexibility in defining the DAC response. Programmable features include power modes, selectable full-scale ranges (±4.096V, ±2.048V, and ±1.024V) and a programmable gain centre point (±2.44mV), adjustable blanking level, temperature compensation range, and temperature offset.

The MAX5383EUT+T utilizes a monolithic,14-bit current output DAC that supports a wide variety of applications such as bridge power supplies, motor control, and piezoelectric actuators. The device integrates a programmable non-volatile memory (EEPROM) that allows the user to store their custom configuration settings and data. This allows the user to quickly change device settings, such as full-scale range, gain center point, temperature compensation range, and temperature offset. Additionally, the device automatically self-calibrates for improved precision.

The MAX5383EUT+T is ideal for applications where there is a need for high current output and high resolution. It is also suitable for industrial and automotive applications that require high accuracy, stability and repeatability. Additionally, the device has a low power design, making it ideal for applications with tight power budgets.

The internal architecture of the MAX5383EUT+T is based on an internal current divider and a switchable resistor network. The current divider consists of two resistors in a differential feedback configuration that divide the analog output voltage. The resistor network consists of eight precision resistors that are adjusted to provide a linear output response.

A thermistor is also included in the device to sense temperature changes. This provides temperature compensation to ensure stable operation over a wide temperature range. The device also includes an internal voltage reference that ensures a very stable output over a wide temperature range.

The MAX5383EUT+T is a versatile device that can be used in a variety of data acquisition and control applications. Its wide range of programmable features and high output accuracy make it an ideal choice for applications requiring high precision and reliability.
