Texas Instruments has introduced two new video amplifiers, that the company claims will help manufacturers meet the demand for energy-efficient home and portable entertainment systems.
The company claimed that 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 volts (V) and 50% lower at 3.3V to help manufacturers achieve ENERGY STAR compliance in set-top boxes (STBs) and Blu-ray DVD players.
The THS7319 is reportedly the lowest profile, three-channel video amplifier supporting EDTV. It is said to deliver 25% lower quiescent current than alternative devices to prolong battery life in portable media devices.
The THS7365 includes integrated 6th order Butterworth fixed filter for HD and SD video. Bypass mode provides up to 250MHz bandwidth to support full HD 1080p60 or UWXGA video. The other features include six-channel operation that supports composite (CVBS) video, S-video and Y’P'(B)P’ component video simultaneously; total supply current of 21.6mA at 5V and 20.7mA at 3.3V that provides the low power consumption necessary for devices seeking ENERGY STAR compliance; and power down disable mode that reduces quiescent current to 0.1uA to save power when the system is idle.
The features of the THS7319 include: integrated 3rd order Butterworth fixed filter for EDTV to provide space savings; low quiescent current of 1.1mA/channel and 0.15uA in power down mode to extend battery life; 1.5 mm x 1.5 mm x 0.40 mm MicrostarCSP package to reduce height by more than 30% for a thinner profile; and wide supply and low voltage operation of 2.5V to 5.5V from a single supply.
The THS7365 is available in a TSSOP-20 package that is reportedly lead-free and green (RoHS-compliant) and priced at $0.70 in 1,000-unit quantities. The THS7319 is available in a MicrostarCSP package for $0.85 in 1,000-unit quantities.
