LMH6646MA.

The LMH6646MA is a dual Operational Amplifier with rail-to-rail input and output. The voltage feedback amplifier offers high speed (55MHz) and low voltage operation (2.7V). Input common-mode voltage range exceeds either supply by 0.3V, enhancing ease of use in multitude of applications where previously only inferior devices could be used. Output voltage range extends to within 20mV of either supply rails, allowing wide dynamic range especially in low voltage applications. Even with low supply current of 650µA/amplifier, output current capability is kept at a respectable ±20mA for driving heavier loads. Important device parameters such as BW, slew rate and output current are kept relatively independent of the operating supply voltage by a combination of process enhancements and design architecture. Both turn-on and turn-off characteristics are well behaved with minimal output fluctuations during transitions.
