LMH6618 Single/LMH6619 Dual

130 MHz, 1.25 mA RRIO Operational Amplifiers

General 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

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

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 max-

imum 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 µA and is offered in the space saving

6-Pin TSOT23 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.
