Part Description
The LMH6645 (single) and LMH6646 (dual), rail-torail input and output voltage feedback amplifiers, offer high speed (55 MHz), and low voltage operation (2.7 V) in addition to micro-power shutdown capability (LMH6647, single). Input common mode voltage range exceeds either supply by 0.3 V, enhancing ease of use in multitude of applications where previously only inferior devices could be used. Output voltage range extends to within 20 mV of either supply rails, allowing wide dynamic range especially in low voltage applications. Even with low supply current of 650 μA/amplifier, output current capability is kept at a respectable ±20 mA 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.
