TI Introduces Video Amplifiers for Component and Composite SDTV

Texas Instruments Incorporated (TI) has introduced a four-channel video buffer that consumes 57 percent less power than its closest competitor. The device also includes a power-down feature to lower system power consumption even more and help enable manufacturers to achieve ENERGY STAR compliance in set-top boxes (STBs) and personal and digital video recorders (PVRs and DVRs). Supporting supply voltage of 2.85-5.5 V, the 4-channel Models THS7374 and THS7375 feature 9.6 mA total quiescent current at 3.3 V supply for all 4 channels. Power-down option further minimizes quiescent current consumption to 0.1 µA, making amplifiers suitable for consumer devices seeking ENERGY STAR compliance. Both models include 6th order 9.5 MHz Butterworth filter used as DAC reconstruction filter or ADC anti-aliasing filter to deliver optimal analog video outputs or inputs.



The THS7374 and THS7375 are available now in a 14-pin TSSOP lead-free (RoHS compatible) and green-compliant package. Suggested resale pricing in quantities of 1,000 is $0.55. In addition, the THS7374 evaluation module (EVM) is available for device testing while the TSW7374EVM enables manufacturers to rapidly design and evaluate SCART applications.
