The LMH6619Q (dual) is a 130 MHz rail-to-rail input and output amplifier designed for ease of use in a wide
range of applications requiring high speed, low supply current, low noise, and the ability to drive complex ADC
and video loads. The operating voltage range extends from 2.7V to 11V and the supply current is typically 1.25
mA per channel at 5V. The LMH6619Q is a member of the PowerWise® family and have an exceptional power-to-
The amplifiers voltage feedback design topology provides balanced inputs and high open loop gain for ease of use and accuracy in applications such as active filter design. Offset voltage is typically 0.1 mV and settling time
to 0.01% is 120 ns which combined with an 100 dBc SFDR at 100 kHz makes the part suitable for use as an
input buffer for popular 8-bit, 10-bit, 12-bit and 14-bit mega-sample ADCs.
The input common mode range extends 200 mV beyond the supply rails. On a single 5V supply with a ground
terminated 150Ω load the output swings to within 37 mV of the ground rail, while a mid-rail terminated 1 kΩ load
will swing to 77 mV of either rail, providing true single supply operation and maximum signal dynamic range on
low power rails. The amplifier output will source and sink 35 mA and drive up to 30 pF loads without the need for
The LMH6619Q is offered in the 8-Pin SOIC package.
