This monolithic integrated circuit provides high reliability in demanding line-carrier communications, laser diode drivers, and motor control applications. The high slew rate provides 1MHz full-power bandwidth and excellent linearity. The OPA561 operates from either a single supply in the range of 7V to 15V or dual power supplies of ±3.5V to ±7.5V for design flexibility. In single-supply operation, the input common-mode range extends below ground. At maximum output current, a wide output swing provides a 12Vp-p capability with a nominal 15V supply. The OPA561 is internally protected against overtemperature conditions and current overloads. In addition, the OPA561 is designed to provide an accurate, userselected, current limit. The current limit can be adjusted from 0.2A ...
