Low-Power Video Amps Target Energy-Efficient Entertainment Systems

Two video amplifiers help designers meet the demand for more energy-efficient home and portable entertainment systems. The THS7365 is an extremely low-power six-channel, fixed filter video amplifier supporting HDTV and SDTV. It consumes 21 percent less power at 5 V and 50 percent less at 3.3 V to help achieve Energy Star compliance in set-top boxes (STBs) and Blu-ray DVD players. A power-down disable mode reduces quiescent current to 0.1 µA to save power when the system is idle. The THS7319 is a very-low-profile, three-channel video amplifier supporting EDTV. It delivers 25 percent lower quiescent current than alternative devices to prolong battery life in portable media devices. A 1.5-mm x 1.5-mm x 0.40-mm tiny MicrostarCSPTM package reduces height by more than 30 percent. The THS7365 is available today in a TSSOP-20 package that is lead-free and RoHS-compliant. It’s priced at $0.70 in 1000-unit quantities. The THS7319 is available today in a tiny MicrostarCSP package for $0.85 in 1000-unit quantities. TEXAS INSTRUMENTS INC., Dallas, TX. (888) 772-3544.
