Thermally Enhanced, 4 mm × 4 mm 16-Lead LFCSP GENERAL DESCRIPTION The ADA4310-1 incorporates a power management function that provides shutdown capabilities and/or the ability to optimize the amplifiers quiescent current. The CMOScompatible, 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. 1/2 ADA4310-1 VMID1 1/2 ADA4310-1 = 1V MID VCC – VEE 2 06027-003 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. Figure 3.

C | Page 9 of 14 ADA4310-1 Data Sheet THEORY OF OPERATION The ADA4310-1 is a current feedback amplifier with high output current capability. With a current feedback amplifier, the current into the inverting input is the feedback signal, and the open-loop behavior is that of a transimpedance, dVO/dIIN or TZ. The open-loop transimpedance is analogous to the open-loop voltage gain of a voltage feedback amplifier. Figure 20 shows a simplified model of a current feedback amplifier. Because RIN is proportional to 1/gm, the equivalent voltage gain is just TZ × gm, where gm is the transconductance of the input stage. Basic analysis of the follower with gain circuit yields Because G × RIN
