Hot-selling and scarce OPA561PWPG4 High-Current High-Speed OPERATIONAL AMPLIFIER IC 20-HTSSOP spot stock

Product Descriptions

The  OPA561  is  a  low-cost,  high-current  operationalamplifier capable of driving up to 1.2A pulses into reactiveloads .  This  monolithic  integrated  circuit  provides  highreliability in demanding line-carrier communications, laserdiode drivers, and motor control applications . The highslew  rate  provides   1MHz  full-power  bandwidth  andexcellent linearity.

The OPA561 operates from either a single supply in therange of 7V to 15V or dual power supplies of ±3.5V to±7 .5V for design flexibility. In single-supply operation, theinput  common-mode  range  extends  below  ground . Atmaximum output current, a wide output swing provides a12Vp-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 adjustedfrom 0.2A to 1.2A with a low-power resistor/potentiometeror  DAC  (Digital-to-Analog  Converter).  The  high-speedcharacteristics of the current control loop provide accuracyeven under pulsed load conditions .

​

The Enable/Status (E/S) pin performs two functions: it canbe  monitored to determine  if the device  is  in thermalshutdown (active LOW), and it can also be forced LOW todisable the output, disconnecting the load .

The OPA561 is available in the miniature, HTSSOP-20PowerPAD  power package . This surface-mount package is thermally enhanced and has a very low thermalresistance .  Operation  is  specified  over  the  extendedindustrial temperature range, −40 C to +125 C .
