GENERAL DESCRIPTION

The ADA4310-1 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 ADA4310-1 is available in a thermally enhanced, 10-lead

MSOP with an exposed paddle for improved thermal conduction

and in a thermally enhanced, 4 mm × 4 mm 16-lead LFCSP.

The ADA4310-1 is rated to work in the extended industrial

temperature range of −40°C to +85°C.

The ADA4310-1 incorporates a power management function

that provides shutdown capabilities and/or the ability to

optimize the amplifiers quiescent current. The CMOS-

compatible, power-down control pins (PD1 and PD0) enable

the ADA4310-1 to operate in four different modes: full power,

medium power, low power, and complete power down. In the

power-down mode, quiescent current drops to only

0.65 mA/amplifier, while the amplifier output goes to a high

impedance state.
