GENERAL DESCRIPTION

Figure 2. Output Swing, V_S= 1.5 V, R_L= 25 Ω

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 appli-

cations, a thermally enhanced 8-lead SOIC EPAD package. Both

packages can operate from −40°C to +85°C.
