Introduction

Data Acquisition - Digital to Analog Converters (DAC) are essential tools for applications that require digital conversion of signals from form A to form B. Conventional DACs have been use for many years, often for the purpose of turning electrical signals into analogue signals for measurement and control systems. A more modern and efficient type of DACs is the LTC2634HUD-HZ12#PBF. This particular DAC provides a high-accuracy 12-bit digital to analogue conversion. It is mainly used in industrial or professional applications andis capable of driving current and voltage outputs of up to +5V/+10V. The LTC2634HUD-HZ12#PBF also provides excellent power and accuracy specifications, facilities that offer superior performance when compared to most standard DACs. In addition to the ADC, the device contains a DAC, an input register, a set of analog multiplexers and a number of control pins in a single monolithic package.

Device Description

The LTC2634HUD-HZ12#PBF is a single device that contains a 12-bit Digital to Analogue Converter. It integrates 12-bit resolution in a variety of voltage and current output formats, including current output ranges up to +5V and +10V. The device provides excellent power and accuracy specifications, with low power consumption and high speed performance. Input to the LTC2634HUD-HZ12#PBF is either a 3-wire digital interface (I2C) or a serial SPI interface. Output is provided in either voltage or current models, providing an analogue output range up to ±10V or +5V/+10V. The device has full-scale output ranges of either 0mA or ±1mA or ±2mA or ±10V or ±20V.

Application Fields and Working Principle

The LTC2634HUD-HZ12#PBF is primarily used in industrial or professional applications where high accuracy and resolution are key requirements. The device’s wide voltage and current output range makes it suitable for driving both digital and analogue signals. Its fast response times and low power consumption make this device suitable for use in applications such as processing motor control signals, level sensing, pressure sensing, and temperature sensing.The device’s digital inputs are translated into analogue output signals by the device’s internal digital-to-analogue converter. The LTC2634HUD-HZ12#PBF has two high-accuracy 12-bit DACs that operate independently but in parallel. The device has two sets of control pins: EOC (End of Conversion) and Data Input. EOC indicates that the conversion from the digital inputs to the analog outputs is complete.The LTC2634HUD-HZ12#PBF’s Data Input pin accepts a 12-bit digital signal that is then translated into analog form by its internal DACs. The device has two DACs, one for current output and one for voltage output. The voltage output DAC is capable of generating output values of up to ±10V and the current output DAC is capable of generating up to ±2mA output. The device has an internal reference voltage that supports a wide range of input data resolution and output voltage/current ranges.

Conclusion

The LTC2634HUD-HZ12#PBF is a high-accuracy DAC that is capable of producing signals up to ±10V or ±2mA. It is suitable for applications in motor control signals, level sensing, pressure sensing, temperature sensing, and other industrial or professional applications. The device has excellent power and accuracy specifications, with fast response times and low power consumption.
