Data Acquisition - Digital to Analog Converters (DAC)Digital to analog converters, often referred to as digital-to-analog converters (DACs), are electronic devices that are used to convert digital signals into corresponding analog signals. DACs are commonly used in digital signal processing (DSP) applications, where digital signals are converted into analogue signals for further signal processing. In particular, the LTC2654BCUF-L16#PBF is a high-precision 16-bit current-output Digital-to-Analog Converters(DAC) with frame signal capability. The LTC2654BCUF-L16#PBF is a 16-bit, current output DAC with a wide range of programmable current outputs. The device includes integrated reference, operating power supply and logic interface. It is ideal for low voltage and low power applications such as audio, industrial and medical applications. The device has an extended temperature range of -40°C to +85°C. The main features of the LTC2654BCUF-L16#PBF include: an easy-to-use parallel or serial I2C/SPI interface, a 0.5µA maximum quiescent current, a user programmable output voltage range, and a 16-bit resolution with ±3LSB INL and ±1LSB DNL accuracy. The device supports up to 3 independent write units with 12 different output configurations. Additionally, the device supports single frame write programming and frame signal programming. The LTC2654BCUF-L16#PBF is designed for applications that require high accuracy at low current consumption over a wide range of output voltage resolutions. Some applications for this device include Power Supply sub-systems, Medical instruments, and Instrumentation systems. The operating principle of the LTC2654BCUF-L16#PBF is simple and yet very effective. The device is an integrated current-output DAC that can receive I2C/SPI input instructions. The instructions are analyzed and the necessary current value is generated. The current is then converted into an analog signal that can be used in the application. The device supports three independent write sections, each of which can produce a different output voltage. The device also supports single-frame write programming and frame signal programming. The LTC2654BCUF-L16#PBF is a highly accurate, modern device with a wide array of features that makes it suitable for a variety of digital signal processing applications. Its wide range of programmable current outputs, its extremely low quiescent current draw, and its 0.5µA maximum current draw make it ideal for low-voltage, low-power applications. Additionally, its extended temperature range of -40°C to +85°C makes it suitable for a variety of conditions and applications. Together, these features make the LTC2654BCUF-L16#PBF one of the most versatile digital-to-analog converters available to the market today.
