The AD8615 is available in 5-lead TSOT-23 package. The AD8616 is available Applications for the parts include portable and low powered in 8-lead MSOP and narrow SOIC surface-mount packages; the instrumentation, audio amplification for portable devices, MSOP version is available in tape and reel only.
