(STMicroelectronics) today introduced two new 300MHz video driver ICs for high-end industrial and medical imaging systems and HDTV set-top boxes and DVD players for driving sharpness on 75Ω video lines High video signal. The new TSH340 and TSH341 features a single 3V-5V supply that can drive near zero voltage video signals.

The TSH340 is a gain internal fixed buffer. It features a small footprint and a small number of peripheral components. To maintain good line matching while ensuring the correct level of the video signal, the gain is set at 6dB. The TSH341 is an operational amplifier with a voltage feedback architecture identical to that of the TSH340, but the gain can be set externally. Both chips feature a 0.25-micron high-speed complementary manufacturing process with bandwidths up to 300MHz and a quiescent current of only 9.8mA.

High slew rate, low distortion, 65MHz gain flatness, 7nV/sqrtHz low input voltage noise, these features make the TSH340 and TSH341 the best choice for driving digital-to-analog converter output on 75Ω video lines. / Output negative voltage rail, working at a single 5V supply, can drive a minimum of 60mV ground signal (production test value), and can directly drive the video signal from the digital-to-analog converter without any bypass capacitor.

Because the use of a single power supply eliminates the need for a negative supply, the single-supply approach helps reduce application complexity and cost, and is an important, easy-to-use component for high-performance video equipment that requires high bandwidth and high signal purity. The specified loads for these two products are 150Ω and 75Ω, and are packaged in tiny SOT23-5 and SO8 plastic packages.

Video amplifiers are equipped with an evaluation board tool optimized for high-speed op amps, including a CD containing data sheets, application notes, technical articles, and user manuals. Now you can order in bulk and order 5,000 pieces for $1.50.
