COS8042ARZ

COS8042ARZ is the tape-and-reel ordering code for the Cosine COS8042, a dual-channel high-speed rail-to-rail input/output operational amplifier in an SOP-8 package — for signal conditioning, active filtering and ADC driving where two matched amplifier channels are needed in one standard footprint. The COS8042 datasheet rates this model at 170 MHz gain-bandwidth with 6.1 mA supply current per channel on supplies from 3.2 V to 12 V, so one dual device covers a differential or two-stage signal path without a second package, and the rail-to-rail swing preserves dynamic range on low rails. Selection advice: quote the full ARZ code — the COS8042AMR in the same ordering table is the MSOP-8 version and the COS8041ARZ is the single-channel part, so package and channel count are decided by the suffix, not the base name; and design against this model's own 170 MHz figure, since other Cosine documents carry an older 160 MHz value for the family. Parameters verified against Cosine documentation.
