OPA567
Rail-to-Rail I/O, 2A
POWER AMPLIFIER
DESCRIPTION
The OPA567 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. Output swing is within 300mV of the supply
rails, with output current of 2A. Smaller loads allow an output
swing closer to the rails.
The OPA567 is unity gain stable, easy to use, and free from
the phase inversion problems found in some power amplifi-
ers. High performance is maintained at voltage swings near
the output rails.
The OPA567 provides an accurate user-selected current
limit set with an external resistor, or digitally adjusted via a
Digital-to-Analog Converter (DAC).
The output of the OPA567 can be independently disabled
using the Enable pin. This feature saves power and protects
the load.
Two flags are provided. The current limit flag, IFLAG, warns of
current limit conditions. TFLAG is a thermal flag that warns of
thermal overstress. The TFLAG pin can be connected to the
Enable pin to provide a thermal shutdown solution.
The OPA567 is available in a tiny 5mm x 5mm Quad
Flatpack No-lead (QFN) package and features an exposed
thermal pad that enhances thermal and electrical character-
istics. It is small and easy to heat sink. The OPA567 is
specified for operation over the industrial temperature range,
–40
°C to +85°C.
