DESCRIPTION
The LMH6618 (single, with shutdown) and LMH6619 (dual) are 130 MHz rail-to-rail input and output amplifiers
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 LMH6618 and LMH6619 are members of the
PowerWise family and have an exceptional power-to-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 150
load the output swings to within 37 mV of the ground rail, while a mid-rail terminated 1 k 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 LMH6618 has an active low disable pin which reduces the supply current to 72 A and is offered in the
space saving 6-Pin SOT package. The LMH6619 is offered in the 8-Pin SOIC package. The LMH6618 and
LMH6619 are available with a
40°C to +125°C extended industrial temperature grade.
