Product Description

The OPA561 is a low-cost, high-current operational amplifier capable of driving up to 1.2A 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 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 over-temperature 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 0.2A to 1.2A with a low-power resistor/potentiometer or DAC (Digital-to-Analog Converter). The high-speed characteristics of the current control loop provide accuracy even under pulsed load conditions.
The Enable/Status (E/S) pin performs two functions: it can be monitored to determine if the device is in thermal shutdown (active LOW), and it can also be forced LOW to disable the output, disconnecting the load.
The OPA561 is available in the miniature, HTSSOP-20 PowerPAD power package. This surface-mount package is thermally enhanced and has a very low thermal resistance. Operation is specified over the extended industrial temperature range, 40°C to +125°C.
