AD8397

Rail-to-Rail, High Output Current Amplifier
Manufactured by:

Product Details

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.

We have tested AD8397 in audio circuit and came to conclusion that this chip is great as a headphone amplifier. We are using C0G caps for powersupply decoupling ( 0.01uF + 0.1uF) and 10uF tantalum capacitor. Chip is powered by two paralleled 12V accu ( about 26V), it's running hot, better to install small radiator. Sound reproduction is great, it is all about pcb design and resistors (we have used vishay dale ptf 0.1% 5ppm resistors in our prototype)/ capacitors. We need more AD8397 for next project, but for standalone headphone amplifier we can say only one word - brilliant.

We needed an ultra low noise opamp for a DAC prototype. This one was perfect. It is being used in a differential setup, with balanced outputs.
