Video Amps Address High Volume Apps May 2004 Issue Published Date: May 03, 2004
Meeting the requirements of high-volume video applications that include RGB signal driving and switching, the TSH8x family of operational amplifiers feature a gain/bandwidth product of 100 MHz and a slew rate of 100 V/µs. The TSH80, TSH81, and TSH82 are single, single with stand-by, and dual-voltage feedback operational amplifiers, respectively. Operating from a 5V supply, each is capable of driving a 150? load with a total harmonic distortion figure of –61 dB at 4 MHz for an output amplitude of 1 Vp-p. Other shared specs include a differential gain of 0.5% and a differential phase of 0.5° at 4.5 MHz, gain flatness of 0.2 dB at 6 MHz for a gain of 2, negative input rail and a rail-to-rail output stage (48 mV from rail), quiescent current of 8 mA, voltage noise of 11 nV/vHz, and operation from 4.5V to 12V dual or single supplies. Prices for the TSH80, TSH81, and TSH82 are $0.35, $0.35, and $0.40 each/5,000. STMICROELECTRONICS INC., Lexington, MA. (781) 861-2650.
