Data acquisition is an important component of almost every research and development environment. It involves collecting data from a variety of physical sources, such as temperature, pressure, and other signals. In order to process this data, digital to analog converters (DAC) are used to convert the digital data into an analog signal to be processed. One such DAC device is the LTC2635HUD-LMI12#PBF, a high-performance, high-resolution, voltage output Digital-to-Analog Converter (DAC). This device provides 12-bit resolution and has an excellent temperature drift of 0.02%/°C.

The LTC2635HUD-LMI12#PBF is designed to provide a wide output range, up to 10.5V full-scale. Its built-in voltage reference ensures that the outputs remain stable with temperature and supply voltage variations. It also features SPI-compatible serial data input and a daisy-chainable feature for simultaneous programming of more than one DAC for multi-channel applications. The device can also be used in a multi-chip configuration, allowing for independent programming of each DAC device.

The LTC2635HUD-LMI12#PBF is well suited for a variety of applications, including DACs for current and voltage output control, data acquisition and conversion, servo control, digital potentiometers and arbitrary waveform generation. It is also ideal for use in medical equipment and instrumentation, communication systems, and audio/video systems. This device is available in a variety of packages, including PDIP, SOIC, TSSOP and LLP packages.

The LTC2635HUD-LMI12#PBF combines a high-accuracy, low-drift voltage reference, a precision internal oscillator, and a 12-bit DAC. The entire device is controlled by a simple 3-wire SPI-compatible interface, making it easy to use and configure. The device also has an optional MODE input that allows for power savings in applications where no programming updates are needed.

The operation of the LTC2635HUD-LMI12#PBF is and easy to understand. When the device is initialising, an “on-the-fly” calibration is performed, and the DAC\'s internal reference is adjusted for factory-set accuracy. Once the device is up and running, a 12-bit data word is sent to the DAC via the SPI interface. The DAC then follows the data word and outputs a precise analog voltage, or current in the case of a current DAC, corresponding to the value of the data word. The DAC\'s output range and resolution is proportional to the full-scale range and resolution of the voltage reference.

The LTC2635HUD-LMI12#PBF is a high-performance, low-drift, 12-bit DAC with a wide output range and excellent temperature drift over temperature. It provides a flexible interface, allowing for simultaneous programming of more than one DAC for multi-channel applications. It is ideal for applications such as DACs for current and voltage output control, data acquisition and conversion, servo control, digital potentiometers, and arbitrary waveform generation.
