Extend Battery Life in Handheld Video Systems by Reducing Video Subsystem Operating and Standby Power
A greater number of portable devices such as digital still cameras, cell phones, and portable media players are adding composite video output connections. In these devices, the video digital-to-analog converter (DAC) generates the composite video signal, which must be lowpass filtered and amplified before reaching the output connector. Design engineers already consider power consumption, total cost, size, and video quality in choosing their video filter amplifiers.
This article describes the additional requirements for the next generation of portable equipment, and shows how the new generation of video filter amplifiers fulfills those requirements.
