The LMH6646MM is a dual rail-to-rail input and output voltage feedback amplifier designed for low voltage operation, with a supply voltage range of 2.5V to 12V. It features a bandwidth of 55MHz and a slew rate of 22V/µs, making it suitable for high-speed applications. The device consumes a low supply current of 650µA per channel while providing a linear output current capability of ±20mA, allowing it to drive heavier loads effectively. The input common mode voltage range exceeds the supply rails by 0.3V, and the output voltage can swing to within 20mV of either rail, ensuring a wide dynamic range. The LMH6646MM is available in an 8-pin MSOP package, making it a compact choice for applications where board space is limited. It is ideal for use in active filters, high-speed portable devices, and multiplexing applications.
