Data Acquisition - Digital to Analog Converters (DAC) are designed to convert a digital signal from a computer or microcontroller into an analog signal, allowing the user to process analog signals in a digital system. The LTC2605CGN#PBF is a 16-bit high-speed digital to analog converter (DAC) designed to provide low-power operation and cost performance in a small 4mm x 4mm TQFN package. This device features a wide operating voltage range from 3V to 6V, allowing it to be used in a broad range of applications requiring both high speed and low-power operation.

The LTC2605CGN#PBF is built on a precision CMOS architecture, offering a high signal-to-noise ratio of 75dB at a signal frequency of 1MHz. This DAC provides a wide operating temperature range of -40°C to 85°C, and is guaranteed to meet the worst-case performance requirements over the full temperature range. The low power dissipation of the device, less than 17mW at 6V and 10mV, gives the device an advantage over other DACs in terms of power consumption and thus, stability.

The core of the LTC2605CGN#PBF is the analog voltage output circuit, which converts the 16-bit replicating input information to a voltage output. The output voltage level is determined by the digital output value from 0V to the reference input voltage of VREF. The settling time of the circuit is 250ns and its accuracy is better than 0.2%.

For many applications, the output voltage must remain stable even when the operating temperature changes. The LTC2605CGN#PBF has a temperature drift specification as low as 0.07ppm/°C. This low drift allows the device to maintain a more stable output voltage over a wide range of temperatures. The low supply current for the device, 250µA at 6V, help reduce power consumption and thermal dissipation interfering with other parts of the system.

In addition to its low current consumption, the LTC2605CGN#PBF offers a fast settling time which is independent of input-code speed and peak-code temperatures. The fast speed turns the device into a powerful solution for systems that require fast response times. This device has also features for protection and monitoring. The write protect feature prevents tampering with the output data, while the fault monitor output indicates power and thermal failures.

The LTC2605CGN#PBF is the ideal solution for high-speed, low-power digital to analog conversion. Its low power operation and accuracy over a wide temperature range make it one of the best solutions for data acquisition applications requiring high speed and low power dissipation. Suitable applications include process control, motor control, data conversion and telemetry systems, among others.
