The LTC2654BIGN-H16#PBF, part of the LTC2654 family of ultra-precise digital-to-analog converters (DAC), is an ideal device for many applications requiring robust and high-precision data acquisition. Each device incorporates an onboard voltage reference and an 8-bit no latency electronic calibration. The voltage range is from −2.5V to +2.5V and features a selectable full-scale output range from 2V to 5V. This highly integrated design also features active RAM and an on-chip digital filter with programmable sample rate for most data acquisition applications requiring low jitter and noise.

The working principle of a DAC is relatively simple. The device receives digital input words and then converts them into an analog voltage or current. This is done by weighing each input bit and accumulating the weighted bits together. DACs use a variety of architectures to accomplish this, but the most common are R-2R Ladder, Integrating, and Current Steering DACs.

The LTC2654BIGN-H16#PBF is a current-steering type DAC. In this type of device, the internal reference accuracy and gain are maintained by setting the appropriate DAC input voltage (a separate V reference). Current is switched in or out of the DAC output according to the digital input values. This type of architecture has high speed and low noise performance. It also allows for high-precision gains, up to +/-0.001%.

The LTC2654BIGN-H16#PBF is ideal for precision data acquisition applications, such as temperature and pressure sensing, medical diagnostics and control, test and measurement, autonomous systems, and process control. The device delivers high accuracy, low noise, and fast response times, making it a great choice for those demanding applications requiring precision and consistency over the long term.

Because the LTC2654BIGN-H16#PBF uses an integrated reference and a programmable filter rate, the system designer can minimize the drift performance and boost the accuracy of their measurement systems. This is especially important in a wide range of field applications in extreme environmental conditions, such as high/low temperature and humidity, as the integral reference maintains its accuracy regardless of varying environmental conditions.

The LTC2654BIGN-H16#PBF is a versatile and economical option for many data acquisition applications. Its extended temperature range, low noise and high accuracy ensure reliable performance in many demanding environments. The programmable digital filter rate provides further optimization and accuracy, making it an ideal choice for those requiring precision results.
