DESCRIPTION

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 powerto-

performance ratio.

The amplifier’s 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

external compensation.

The LMH6619Q is offered in the 8-Pin SOIC package.
