LTC2758BILX#PBF

Data Acquisition - Digital to Analog Converters (DAC)

The LTC®2758BILX#PBF is a 10-bit, dual digital-to-analog converter (DAC) from Linear Technology (LT). This type of device is often used in data acquisition applications, such as those dealing with temperature, voltage, current, and humidity control. The LTC2758BILX#PBF architecture consists of an 8-bit parallel input and a 10-bit serial output, which is analogous with the digital equivalent of a waveform. Its 10-bit resolution and ± 10V output range make it a suitable choice for various test and measurement applications.

Working Principle

The working principle of LTC2758BILX#PBF is based on the output signals generated by the internal DAC chips which are of either 10-bit resolution or 8-bit resolution. The 10-bit resolution provides a ± 10V output range and the 8-bit resolution provides a programmable output range of up to ± 10V. The voltage range is determined by the values of the external reference voltage (REF) and the internal reference voltage (VREF). The data is then stored in the register and the DAC chips are enabled to output the corresponding analog voltage. The output from the DAC chips is then amplified and filtered before being output from the device. In comparison with other DACs, the LTC2758BILX#PBF offers superior linearity and low power consumption.

The LTC2758BILX#PBF is an ideal choice for applications such as data acquisition systems, digital data acquisition, power supply control, temperature and humidity control, pressure control, as well as digital generation of waveforms and pulse-width modulation (PWM). With its extended temperature range and high resolution, the LTC2758BILX#PBF is a versatile device that is suitable for a wide range of applications.
