Data Acquisition - Digital to Analog Converters (DAC) utilize an integrated circuit (IC) that takes in a digital value and converts it into a corresponding analog voltage or current output. The LTC2631CTS8-LM10#TRPBF from Linear Technology is a great example of this IC. This versatile IC family offers a wide range of DAC resolutions that range from 8 bits up to 16. The LTC2631CTS8-LM10#TRPBF is a 10-bit, non-volatile, Voltage Output DAC that offers excellent performance for modern electronic applications.

The DAC offers excellent relative accuracy values of 0.5% mid-code and 8/10-bit fixed range (models) and 0.25% mid-code and 10/12/14/16-bit adjustable range (models). It utilizes a 3.0V - 5.5V single supply and can generate an analog reference voltage or adjust external references. It features an I2C serial interface that is used to change the output voltage, power the device on/off, reset, load the EEPROM (electrically erasable programmable read only memory), and write back the voltage to the EEPROM.

The LTC2631CTS8-LM10#TRPBF can operate over the commercial temperature range of -40°C to 85°C. In addition, the device is ESD (electrostatic discharge) protected, allowing it to handle the high level of ESD pulses and charge accumulation.

The LTC2631CTS8-LM10#TRPBF is an ideal device for many data acquisition and embedded applications that require digital to analog conversion with excellent accuracy. It is especially suited for automotive, industrial and medical applications because of its wide single supply, non-volatile storage, low power requirements and high accuracy.

The working principle of the LTC2631CTS8-LM10#TRPBF is simple. An ‘x’ bit digital code is fed into the input of the DAC, which is then compared to a reference voltage through a network of resistors. The analog output is then generated inversely proportional to the ‘x’ bit digital code that is fed into the DAC.

An example of a DAC conversion can be seen in the following illustration. Let us assume that we have an 8-bit DAC with a reference voltage of 5V. The 8-bit digital code of 10011 101 is fed into the input of the DAC. The analog output voltage in this case is 2.34V. This happens because the bit wise comparison of the digital code (1\'s = 5V and 0\'s = 0V) results in the analog output of 2.34V.

The LTC2631CTS8-LM10#TRPBF is a versatile and accurate digital to analog converter. It offers excellent performance characteristics and will be a great addition to any data acquisition application.
