AD8397:  Rail-to-Rail, High Output Current Amplifier

Product Description

The AD8397 has 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 AD8397 ideal for applications that require a large signal swing into a heavy load.

Fabricated with ADI's high speed eXtra Fast Complementary Bipolar High Voltage (XFCB-HV) process, the high bandwidth and fast slew rate of the AD8397 keep distortion to a minimum while also dissipating minimum power. The AD8397 is available in a standard 8-lead SOIC package and, for higher power applications, a thermally enhanced 8-lead SOIC EPAD package. Both packages can operate from -40°C to +85°C.
