High-speed op-amps from TI, in a somewhat challenging WSON8-package...
OPA858 is a 5.5 GHz GBWP FET-input amplifier (stable at gains >= 7V/V), and the OPA859 looks like a slower 1.8 GHz unity-gain stable version.
OPA855 is a 8 GHz bipolar input opamp, gain >=7V/V.
These should be useful where OPA847 and OPA659 were used previously, e.g. in high-speed transimpedance amplifiers.
