The LMH6704 includes on chip feedback and – AV = +2, VO = 2 VPP 400 MHz gain set resistors, simplifying PCB layout while • High output current ±90 mA providing user selectable gains of +1, +2 and −1 V/V. • Very low distortion The LMH6704 provides a disable pin, which places the amplifier in a high output impedance, low power – 2nd/3rd harmonics (10 MHz, RL = 100Ω): mode. The Disable pin may be allowed to float high. −62/−78dBc – Differential gain/Differential phase: With a 650 MHz Small Signal Bandwidth (AV = +1), 0.02%/0.02° full power gain flatness to 200 MHz, and excellent Differential Gain and Phase, the LMH6704 is • Low noise 2.3nV/ √Hz optimized for video applications. High resolution video • High slew rate 3000 V/ μs systems will benefit from the LMH6704 ability to drive • Supply current 11.5 mA multiple video loads at low levels of differential gain or differential phase distortion. APPLICATIONS The LMH6704 is constructed with proprietary high • HDTV, NTSC and PAL video systems speed complementary bipolar process using proven current feedback circuit architectures. It is available in • Video switching and distribution 8 Pin SOIC and 6 Pin SOT-23 packages. • ADC driver • DAC buffer • RGB driver • High speed multiplexer CONNECTION DIAGRAM 6 Pin SOT-23 Top View 8 Pin SOIC Top View See Package Number D0008A See Package Number DBV0006A 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 LMH is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
