SN761666DGKRG4 is a triple 8-bit digital-analog converter (DAC) with improved linearity and gain accuracy. It is designed to simplify the design of video and image processing in applications such as liquid-crystal displays (LCDs), cameras, and video decoders.

This triple 8-bit DAC features a two-channel feedback architecture, allowing for improved linearity and gain accuracy at high video frequencies. The comparison gain on each channel can be adjusted through eight different settings, which can be used to optimize linearity and gain settings. The SN761666DGKRG4 also features a low power supply voltage range, meaning that it can be used in low power applications. In addition, it offers a wide input dynamic range and high output rate, making it suitable for high-speed video applications.

The SN761666DGKRG4 is used in video applications such as HDTV, LCD, MPEG-2 and MPEG-4 encoding, and for PC-TV applications. Its two-channel feedback architecture and high output rate allow it to be used in demanding video applications that require precise linearity and gain accuracy. The SN761666DGKRG4 is also ideal for applications that require high resolution and wide input dynamic range, such as PC-SANYO. The SN761666DGKRG4’s low power consumption and wide input range make it an attractive option for applications that require a power efficient solution.

The SN761666DGKRG4 operates on a single supply voltage of 5V and has an output current range of 16 to 32mA. The maximum output current of 32mA is suitable for video applications that require a wide video dynamic range, such as LCDs and HDTVs. The gain accuracy on each channel can be adjusted through eight different settings, allowing for precise linearity and gain settings. The SN761666DGKRG4 also features a low power supply voltage range, meaning that it can be used in low power applications.

The working principle of the SN761666DGKRG4 is based on a two-channel feedback architecture. The feedback circuits control the gain and offset of each channel and the output signals are processed by a comparator/accumulator circuit. This comparison gain on each channel can be adjusted through eight different settings, which can be used to optimize linearity and gain settings. The comparator/accumulator circuit sends the output signals to the DAC output, which can then be used to generate a video signal.

In conclusion, the SN761666DGKRG4 is a versatile triple 8-bit DAC with improved linearity and gain accuracy. It is designed to simplify the design of video and image processing applications such as LCDs, cameras, and video decoders. The two-channel feedback architecture and adjustable gain settings make the SN761666DGKRG4 an ideal choice for applications that require precise linearity and gain accuracy. In addition, its low power consumption and wide input range make it suitable for low power applications.
