Two new video amplifiers from Texas Instruments help manufacturers meet the demand for more energy-efficient home and portable entertainment systems. The THS7365 is the lowest power six-channel, fixed filter video amplifier supporting HDTV and SDTV. The device delivers 21 percent lower power consumption at 5 volts (V) and 50 percent lower at 3.3 V to help manufacturers achieve ENERGY STAR compliance in set-top boxes (STBs) and Blu-ray DVD players.

The THS7319 is the lowest 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.

Key features and benefits of the THS7365
· Integrated 6th order Butterworth fixed filter for HD and SD video. Bypass mode provides up to 250 MHz bandwidth to support full HD 1080p60 or UWXGA video
· Six-channel operation supports composite (CVBS) video, S-video and Y'P'BP'R component video simultaneously
· Total supply current of 21.6 mA at 5 V and 20.7 mA at 3.3 V provides the low power consumption that is important for devices seeking ENERGY STAR compliance
· Power down disable mode reduces quiescent current to 0.1uA to save power when the system is idle
· Wide supply and low voltage operation of 2.6 V to 5.5 V from a single supply maximizes design flexibility

Key features and benefits of the THS7319
· Integrated 3rd order Butterworth fixed filter for EDTV provides space savings
· Low quiescent current of 1.1 mA/channel and 0.15 uA in power down mode extends battery life
· 1.5 mm x 1.5 mm x 0.40 mm tiny MicrostarCSPTM package reduces height by more than 30 percent for a thinner profile
· Wide supply and low voltage operation of 2.5 V to 5.5 V from a single supply maximizes design flexibility
