MAX5134AGUE+

The MAX5134AGUE+ digital-to-analog converter (DAC) is a reliable, low-noise DAC designed for use in a variety of precision data acquisition systems. Its wide dynamic range and temperature range make it suitable for several application fields. It offers high linearity at 0°C to 70°C and can be used for industrial and automotive systems, test and measurement, auto-calibration and correction, reference voltage generators, and battery-operated data acquisition systems. The MAX5134AGUE+ provides a 16-bit resolution and uses an integrated voltage trim circuit to achieve high accuracy over temperature and supply voltage variation.

The MAX5134AGUE+ DAC has an input stage that allows differential or single-ended input signals to be used. It also has a gain selection circuit that allows users to choose from 5 gain ranges from x2 to x32. The device features adjustable output voltage ranges from 0.3V to 4.096V. Additionally, the MAX5134AGUE+ provides fast settling time, a wide power supply range from 2.7V to 5.5V, and a power-down mode for battery-operated systems.

The MAX5134AGUE+ DAC has a simple, efficient design to produce consistently precise output from input signals. The device converts digital inputs with 0-255 digital codes into an output voltage that follows the equation: Vo(From0 to 4.09V) = Gain x (Dip/255 x Vref). Vref is a user-selectable reference voltage which is derived from the supply voltage, and dip represents a setting in 4PDIP gain selections. The MAX5134AGUE+ has a low output impedance of 0.65Ω with a 1mA output, allowing the device to drive capacitive loads up to 100pF and to achieve higher output voltage density.

The MAX5134AGUE+ DAC also features a very low quiescent power consumption of 350µW for a 1.8 V supply voltage and 650µW for a 3.3 V supply voltage. This is especially beneficial for using the device in battery-powered applications, helping to extend the battery life. The device also has a built-in power-on reset (POR) circuit to ensure that the power-up sequence is initiated properly and the device is reset.

The MAX5134AGUE+ offers a high level of accuracy and reliability for a wide range of applications, making it an excellent choice for digital-to-analog conversion in data acquisition and control systems. The device’s 16-bit resolution and selectable gain yields high accuracy over a broad range of input signals. The MAX5134AGUE+ has a wide temperature range and adjustable output voltage range, allowing the device to be used in a variety of applications and environments. The device’s extremely low power consumption and power-down mode also make it well suited for use in battery-operated systems.
