GENERAL DESCRIPTION

The ADA4311-1 is comprised of two high speed, current

feedback operational amplifiers. The high output current, high

bandwidth, and fast slew rate make it an excellent choice for

broadband applications requiring high linearity performance

while driving low impedance loads.

The ADA4311-1 incorporates a power management function

that provides shutdown capabilities and the ability to optimize

the quiescent current of the amplifiers. The CMOS-compatible,

power-down control pins (PD1 and PD0) enable the ADA4311-1

to operate in four different modes: full power, medium power,

low power, and complete power-down. In power-down mode, the

quiescent current drops to only 1.0 mA/amplifier, while the outputs

go to a high impedance state.

The ADA4311-1 is available in a thermally enhanced, 10-lead

MSOP with an exposed paddle for improved thermal conduction.

The ADA4311-1 is rated to work in the extended industrial

temperature range of −40°C to +85°C.
