The MAX5812LEUT+T is a digital to analog converter (DAC) with an integrated driver and enables low voltage and low power operation for data acquisition and control applications. The device achieves superior linearity performance at a wide temperature range. It operates with a single supply voltage, making it ideal for battery operated and power sensitive applications.

The MAX5812LEUT+T DAC integrates a 12-bit DAC and 12-bit laser trimmed driver. Its high output current capability of up to 100mA can be adjusted with external resistor divider. The on-chip driver supports an effective voltage output range of 0.6V to VCC in both push-pull and open-drain configurations. The power consumption of the device is 0.9mW at 5MHz conversion rate, improving the system power efficiency.

The MAX5812LEUT+T features a digital control register for setting DAC resolution, output range, gain, and software or hardware reset modes. The control register is accessed via 2-wire serial interface (I2C or SMBus compatible). Output data can be updated via the 12-bit serial input. The device has an integrated power-on reset (POR) circuit and an internal supply voltage monitor (VS).

The MAX5812LEUT+T is designed for digital data acquisition and control applications. Its superior linearity performance, low voltage and low power operation, and I2C compatible interface make it suitable for various data acquisition and control applications such as industrial and automotive environment control, motor control, medical instrumentation device control and measurement, etc.

The working principle of the MAX5812LEUT+T is quite straightforward. When the voltage of the output terminal is compared with the reference voltage, the two signals are passed to the analog-to-digital converter. The analog-to-digital converter then converts the voltage into a digital code and sends it to the DAC. The DAC then converts the digital code into an analog voltage and this voltage is applied to the output terminal. The output voltage of the DAC can be adjusted by changing the value of the reference voltage as well as by varying the digital code.

The MAX5812LEUT+T features a high-order noise shaping feature which minimizes the total harmonic distortion, ensuring that the output voltage is free from undesirable noise spikes. The embedded temperature sensor helps to remove thermal error when changing the output voltage. This ensures that the output voltage is free from thermal error or fluctuation.

As data acquisition and control applications become more and more advanced, devices like the MAX5812LEUT+T become essential to ensure reliability, accuracy, and functionality. With its superior linearity performance, wide temperature range operation, low voltage and low power operation, and I2C compatible interface, the MAX5812LEUT+T makes an excellent choice for anyone looking for a high-quality DAC solution.
