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.

Maximum Power Dissipation
The maximum safe power dissipation for the
ADA4310-1
is
limited by the associated rise in junction temperature (T
J
) on
the die. At approximately 150°C, which is the glass transition
temperature, the plastic changes its properties. Even temporarily
exceeding this temperature limit can change the stresses that the
