Product Description

Description
The LMH6645 (single) and LMH6646 (dual), rail-to-rail 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.
Features
• (VS = 2.7V, TA = 25°C, RL = 1kΩ to V+/2, AV = +1. Typical Values Unless Specified.
• −3dB BW 55 MHz
• Supply Voltage Range 2.5 V to 12 V
• Slew Rate 22 V/μs
• Supply Current 650 μA/channel
• Output Short Circuit Current 42 mA
• Linear Output Current ±20 mA
• Input Common Mode Voltage 0.3 V Beyond Rails
• Output Voltage Swing 20 mV from Rails
• Input Voltage Noise 17 nV/√Hz
• Input Current Noise 0.75 pA/√Hz
Applications
• Active Filters
• High Speed Portable Devices
• Multiplexing Applications (LMH6647)
• Current Sense Buffer
• High Speed Transducer Amp
