The AD8397ARDZ-REEL comprises two voltage feedback operational amplifiers capable of driving heavy loads with excellent linearity. The common-emitter, rail-to-rail output stage surpasses the output voltage capability of typical emitter-follower output stages and can swing to within 0.5 V of either rail while driving a 25 Ω load. The low distortion, high output current, and wide output dynamic range make the AD8397ARDZ-REEL ideal for applications that require a large signal swing into a heavy load.
Fabricated with Analog Devices, Inc., high speed extra fast complementary bipolar high voltage (XFCB-HV) process, the high bandwidth and fast slew rate of the AD8397ARDZ-REEL keep distortion to a minimum. The AD8397ARDZ-REEL is available in a standard 8-lead SOIC_N package and, for higher power dissipating applications, a thermally enhanced 8-lead SOIC_N_EP package. Both packages can operate from −40°C to +85°C.
