Power video amplifiers

Two video amplifiers from Texas Instruments can 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% lower power consumption at 5 V and 50% lower at 3.3 V to help manufacturers achieve Energy Star compliance in set-top boxes and Blu-ray DVD players.

The THS7319 is the lowest profile, three-channel video amplifier supporting EDTV. It delivers 25% lower quiescent current than alternative devices to prolong battery life.

Features of the THS7365 include: 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 video, S-video and Y<0x0027>P<0x0027>_BP<0x0027>_R component video simultaneously; total supply current of 21.6 mA at 5 V and 20.7 mA at 3.3 V; power down disable mode reduces quiescent current to 0.1 µA; wide supply and low voltage operation of 2.6 to 5.5 from a single supply maximises design flexibility.

Features of the THS7319 include: integrated 3rd order Butterworth fixed filter for EDTV provides space savings; low quiescent current of 1.1 mA/channel and 0.15 µA in power down mode; 1.5 mm x 1.5 mm x 0.40 mm MicrostarCSP package; wide supply and low voltage operation of 2.5 to 5.5 from a single supply.
