73 wide variety of applications. Filters, integrators, photodiode 02 Figure 5. 8-Lead MSOP (RM Suffix), Figure 6. 14-Lead TSSOP (RU Suffix) amplifiers, and high impedance sensors all benefit from the 8-Lead SOIC_N (R Suffix) combination of performance features. Audio and other ac applications benefit from the wide bandwidth and low distortion. Applications for these amplifiers include optical control loops, portable and loop-powered instrumentation, and audio amplification for portable devices. The AD8605, AD8606, and AD8608 are specified over the extended industrial temperature range (−40°C to +125°C). The AD8605 single is available in 5-lead SOT-23 and 5-ball WLCSP packages. The AD8606 dual is available in an 8-lead MSOP, an 8-ball WLSCP, and a narrow SOIC surface-mounted package. The AD8608 quad is available in a 14-lead TSSOP package and a narrow 14-lead SOIC package. The 5-ball and 8-ball WLCSP offer the smallest available footprint for any surface-mounted operational amplifier. The WLCSP, SOT-23, MSOP, and TSSOP versions are available in tape-and-reel only. 1 Protected by U.S. Patent No. 5,969,657.
