Data acquisition—Digital to Analog Converters (DAC) are necessary for many operations, particularly those involving the conversion of digital signals into analog signals. The popular LTC2655BCGN-L16#PBF is a sixteen-bit, voltage-output digital-to-analog converter (DAC) that has found its way into many industrial applications such as precision instrumentation, data acquisition and medical instrumentation.

The LTC2655BCGN-L16#PBF exercises its functions through a tiny 6-pin SOT23 package. It operates over a range of supply voltages from 3.3V to 5.5V and is offered with a choice of seven internal gain settings resulting in the ability to provide a family of isothermal DACs. Additionally, the device comes with an integrated EEPROM serving as high-value storage for multiple application settings that can be used by the converter upon power-up or as a back-up during system upgrades.

The converter also has an internal voltage reference and supports an external one. The gain selection pins are abled to set the full-scale output to either 5V or 10V, while nine unipolar pressure options provide resolution and a wide bandwidth of 0.02-20V/μs. If a more precise voltage output is needed, the LTC2655BCGN-L16#PBF can connect externally to a reference voltage to configure its digital-analog output. With a refresh rate of maximum 16MHz, the converter can be configured in voltage output mode or current output mode.

The LTC2655BCGN-L16#PBF also has a transparent latch with an input register that stores supplied data, enabling uninterrupted data updates. The converter is alos operable in both polling and interrupt modes, with huge flexibility due to the DAC\'s default polarity code output, programmable polarity, as well as an unipolar output coding option. The sixteen bit coding also produces a high resolution output, while the converter\'s 3MSPS conversion rate involves shunting the output current through an external resistor to provide the required analog output.

The LTC2655BCGN-L16#PBF is incredibly versatile and has the capabilities to address a wide range of analogue configurations that require precision DACs, making it ideal for industrial uses. Its ability to dynamically switch between output modes to facilitate isothermal DACs whilst offering high resilience to in-rush currents and its programmability all make this device a force to be reckoned with.
