Description
General part information
OPA561 Series
The OPA561 is a low-cost, high-current operational amplifier capable of driving up to 1.2-A pulses into reactive loads. This monolithic integrated circuit provides high reliability in demanding line-carrier communications, laser diode drivers, and motor-control applications. The high slew rate provides 1 MHz of full-power bandwidth and excellent linearity.
For design flexibility, the OPA561 operates from either a single supply in the range of 7 V to 15 V or dual power supplies of ±3.5 V to ±7.5 V. In single-supply operation, the input common-mode range extends below ground. At maximum output current, a wide output swing provides a 12 V PP capability with a nominal 15‑V supply.
The OPA561 is internally protected against overtemperature conditions and current overloads. In addition, the OPA561 is designed to provide an accurate, user-selected, current limit. The current limit can be adjusted from 0.2 A to 1.2 A with a low-power resistor or potentiometer, or DAC (digital-to-analog converter). The high-speed characteristics of the current control loop provide accuracy, even under pulsed-load conditions.
