Data Acquisition - Digital to Analog converters (DAC) are used in many types of applications and offer a wide range of flexibility and accuracy. The LTC2634CMSE-HMI12#PBF is a 12-Bit, pin-programmable Digital to Analog Converter (DAC) designed for high speed, I/O flexibility and low power. The device family offers a broad range of multi-bit resolutions, pin programmability and high speed operation at low currents.

Input Data and Digital Interface

The LTC2634CMSE-HMI12#PBF features a 12-bit monotonic, a two-wire pin-selectable input interface. Inputs can be configured for Serial Peripheral Interface (SPI) format with 3- or 4-wire serial interface, as well as for Inter-Integrated Circuit (I2C) format. This allows for operation in a wide range of applications, and eliminates the custom digital programming needed for some applications.

Output Ranges and Resolution

The LTC2634CMSE-HMI12#PBF is available in several output ranges, including +2.5V, +3V, +5V, -2.5V, -3V, and -5V. Resolution of output is 12-bits, meaning that the output voltage can be adjusted with 0.015% accuracy. This device is capable of sourcing load currents up to 200mA, and sinking up to 20mA.

Power Supply and Application

The LTC2634CMSE-HMI12#PBF requires a single +5V supply voltage and is provided as a mid-packaged Plastic 5-lead MOTOROLA ULN package. Its power consumption is very low, with high speed operations that won\'t create any noise, making it the ideal power supply for high-performance DAC applications, such as industrial automation, audio production and multiple output digital control. Its versatile interface and customizeable outputs make it an ideal choice for many digital-to-analog conversion applications.

Working Principle

The working principle of the LTC2634CMSE-HMI12#PBF is relatively simple. An analog voltage is generated in a given range by a combination of six voltage levels, five of which are provided on the device\'s terminal pins. The sixth is provided by the equivalent resistance on the device. The device works by referring incoming digital input data to the equivalent resistance. The output voltage is then varied based on the values of the equivalent resistance.

Conclusion

The LTC2634CMSE-HMI12#PBF offers many features and benefits for digital-to-analog applications. Its small size and self-configuration make it an excellent choice for many applications. Its high speed operations, low power consumption and excellent resolution help to ensure a high quality product. Finally, its wide range of output ranges and interface make it suitable for many applications.
