2730 amplifiers, and high impedance sensors all benefit from the Figure 5. 8-Lead MSOP (RM Suffix), Figure 6. 14-Lead TSSOP (RU Suffix) combination of performance features. Audio and other ac 8-Lead SOIC_N (R Suffix) 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.
