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 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.
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.
