The AD8615/AD8616/ AD8618 offer the highest output drive capability of the DigiTrim® family, which is excellent for audio line drivers and other low The AD8615/AD8616/AD8618 are specified over the extended impedance applications. industrial temperature range (−40°C to +125°C). 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. The AD8618 is portable phone headsets, bar code scanners, and multipole available in 14-lead SOIC and TSSOP packages. filters. The ability to swing rail-to-rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in single-supply systems.
