AD8397

Data Sheet FEATURES Dual operational amplifier Voltage feedback Wide supply range from 3 V to 24 V Rail-to-rail output Output swing to within 0.5 V of supply rails High linear output current 310 mA peak into 32 Ω on ±12 V supplies while maintaining −80 dBc SFDR Low noise 4.5 nV/√Hz voltage noise density at 100 kHz 1.5 pA/√Hz current noise density at 100 kHz High speed 69 MHz bandwidth (G = 1, −3 dB) 53 V/μs slew rate (RLOAD = 25 Ω) APPLICATIONS Twisted-pair line drivers Audio applications General-purpose ac applications GENERAL DESCRIPTION The AD8397 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 AD8397 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 AD8397 keep distortion to a minimum. The AD8397 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. VOUT (V) VOUT (V) Rail-to-Rail, High Output Current Amplifier AD8397...
