GENERAL DESCRIPTION
The ADA4310-1 is comprised of two high speed, current The ADA4310-1 is available in a thermally enhanced, 10-lead feedback operational amplifiers. The high output current, high MSOP with an exposed paddle for improved thermal conduction bandwidth, and fast slew rate make it an excellent choice for and in a thermally enhanced, 4 mm × 4 mm 16-lead LFCSP. broadband applications requiring high linearity performance The ADA4310-1 is rated to work in the extended industrial while driving low impedance loads. 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-
ADA4310-1
compatible, power-down control pins (PD1 and PD0) enable
V 1 MID
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
1/2
0.65 mA/amplifier, while the amplifier output goes to a high
