Description
The CD8605, CD8606, and CD8608 are single, dual, and quad rail-to-rail input and output, single-supply amplifiers. They feature very low offset voltage, low input voltage and current noise, and gain bandwidth product characteristic of up to 8.7MHz. The CD8605, CD8606, and CD8608 are specified over the extended industrial temperature range (−40°C to +125°C). The CD8605 single is available in 5-lead SOT-23 and 5-ball WLCSP packages.
The CD8606 dual is available in an 8-lead MSOP, an 8-ball WLSCP, and a narrow SOIC surface-mounted package. The CD8608 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.
