The wide bandwidth is well suited for video or slow-scan applications, while the low power consumption and low quiescent current make the ISL45042IR-T ideal for applications that draw low power.

Applications

The ISL45042IR-T is ideally suited for a range of linear and video-processing applications. These include gaming consoles, computer sets, medical imaging equipment, LCD monitors, and LED/LCD TVs.

Gaming consoles may use the ISL45042IR-T as a DAC to create video images during game play. In computer sets, the ISL45042IR-T can be used to improve video quality during computer operation, such as scrolling or graphic manipulation. The ISL45042IR-T has also been used in medical imaging equipment to process digital images quickly and accurately. In LCD monitors and LED/LCD TVs, the ISL45042IR-T is used to ensure that the image quality produced by the device remains high and meets the demanding standards of these products.

Working Principle

The ISL40042IR family is built on Intersil’s precision low-voltage DAC technology. The ISL45042IR-T uses a 5-bit digital-to-analog converter that can create high-accuracy and low-resolution output. The ISL45042IR-T can output up to 1.2V p-p, and it is capable of producing voltages from -0.6V to +1.2V p-p. It is powered by a single supply operating between 1.1V and 1.8V.

The ISL45042IR-T can be programmed to output either a Low Voltage Digital (LVD) signal or a Voltage Output signal. The LVD signal is a binary-coded signal (using 1s and 0s) whose voltage values range from -1.2V to +3.3V. The Voltage Output signal is a reference voltage signal whose voltage values range from -1.2V to +1.2V. These signals can be used for a variety of video-processing applications.

The ISL45042IR-T includes programmable multipliers and scaling settings, allowing the user to precisely adjust the amplitude and/or frequency of the output signal. The device also offers a wide range of sample rate options to ensure that the signal is able to keep up with the demands of the application. Finally, the ISL45042IR-T features low power consumption and low quiescent current, making it ideal for low-power applications.

Conclusion

The ISL45042IR-T from Intersil Corporation is a versatile, quick-response digital-to-analog converter with a range of applications in linear and video-processing. Its precision low-voltage DAC technology, wide range of features, and low power consumption make it ideal for gaming consoles, computer sets, medical imaging equipment, LCD monitors, and other linear-video applications. In addition, the ISL45042IR-T can output both Low Voltage Digital and Voltage Output signals for a variety of video-processing applications.
