LMH6609 is an ultra wideband, unity gain stable, low power, voltage feedback op amp that offers 900MHz bandwidth at a gain of 1, 1400V/µs slew rate and 90mA of linear output current. The LMH6609 is designed with voltage feedback architecture for maximum flexibility especially for active filters and integrators. The LMH6609 has balanced, symmetrical inputs with well-matched bias currents and minimal offset voltage. With Differential Gain of .01 and Differential Phase of .026 the LMH6609 is suited for video applications. The 90mA of linear output current makes the LMH6609 suitable for multiple video loads and cable driving applications as well. The recommended supply voltage range of 6V to 12V and is specified at 6.6 and 10V. A low supply current of 7mA (at 10V supply) makes the LMH6609 useful in a wide variety of platforms, including portable or remote equipment that must run from battery power. The LMH6609 is available in the industry standard 8-pin SOIC package and in the space-saving 5-pin SOT package. The LMH6609 is specified for operation over the -40°C to +85°C temperature range. The LMH6609 is manufactured in National Semiconductor’s state-of-the-art VIP10™ technology for high performance.
The LMH6609 is a unity‑gain stable, low‑power voltage‑feedback operational amplifier designed for video and RF applications. It offers a 900 MHz -3 dB bandwidth, 1400 V/µs slew rate, and up to 90 mA linear output current, making it suitable for driving multiple video loads and cable‑driven circuits.
The device operates from a 6 V to 12 V supply, draws only 7 mA no‑load current, and is available in 8‑pin SOIC and 5‑pin SOT‑23 packages. It is specified for -40 °C to +85 °C operation and includes robust ESD protection (2000 V HBM).
