Texas Instruments OPA561 High-Speed Operational Amplifier
Texas Instruments OPA561 High-Speed Operational Amplifiers (Op Amps) are low-cost, high-current op amps 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 of full-power bandwidth and excellent linearity. For design flexibility, the OPA561 operates from a single supply of 7V to 15V or dual power supplies of ±3.5V to ±7.5V. In single-supply operation, the input common-mode range extends below ground. A wide output swing provides a 12VPP capability at maximum output current with a nominal 15V supply.
The OPA561 is internally protected against overtemperature conditions and current overloads. In addition, it 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 Texas Instruments OPA561 is available in a miniature HTSSOP-20 PowerPAD integrated circuit package. This surface-mount package is thermally enhanced and has a very low thermal resistance. Operation is specified over the industrial temperature range of 0°C to 125°C.
