SBOS264A – DECEMBER 2002 – REVISED DECEMBER 2003  
Rail-to-Rail I/O, 2A  
POWER AMPLIFIER  
DESCRIPTION  
FEATURES  
The OPA569 is a low-cost, high-current, operational amplifier  
designed for driving a wide variety of loads while operating on  
low-voltage supplies. It operates from either single or dual  
supplies for design flexibility and has rail-to-rail swing on the  
input and output. Typical output swing is within 150mV of the  
supply rails, with output current of 2A. Output swing closer to  
the rails is achievable with lighter loads.  
● HIGH OUTPUT CURRENT: 2A  
● OUTPUT SWINGS TO: 150mV of Rails with IO = 2A  
● THERMAL PROTECTION  
● ADJUSTABLE CURRENT LIMIT  
● TWO FLAGS: Current Limit and Temperature  
Warning  
The OPA569 is unity-gain stable, has low dc errors, is easy  
to use, and free from the phase inversion problems found in  
some power amplifiers. High performance is maintained at  
voltage swings near the output rails.  
● LOW SUPPLY VOLTAGE OPERATION: 2.7V to 5.5V  
● SHUTDOWN FUNCTION WITH OUTPUT DISABLE  
● SMALL POWER PACKAGE: SO-20 PowerPAD™  
The OPA569 provides an accurate user-selected current  
limit that is set with an external resistor, or digitally adjusted  
via a Digital-to-Analog Converter.  
APPLICATIONS  
● THERMOELECTRIC COOLER DRIVER  
● LASER DIODE PUMP DRIVER  
● VALVE, ACTUATOR DRIVER  
● SYNCHRO, SERVO DRIVER  
● TRANSDUCER EXCITATION  
The OPA569 output can be independently disabled using the  
Enable pin, saving power and protecting the load.  
The IMONITOR pin provides a 1:475 bidirectional copy of the  
output current. This eliminates the need for a series current  
shunt resistor, allowing more voltage to be applied to the  
load. This pin can be used for simple monitoring, or feedback  
control to establish constant output current.  
● GENERAL LINEAR POWER BOOSTER FOR  
OP AMPS  
Two flags are provided: one for warning of thermal over-  
stress, and one for current limit condition. The Thermal Flag  
pin can be connected to the Enable pin to provide a thermal  
shutdown solution.  
● PARALLELING OPTION FOR HIGHER

Packaged in the Texas Instruments PowerPAD™ package,  
it is small and easy to heat-sink. The OPA569 is specified for  
operation over the industrial temperature range, –40°C to  
+85°C.
