The OPA564 is a high-current operational amplifier ideal for driving up to 1.5 A in reac-
tive loads and provides high reliability in demanding power-line communications and
motor contr
ol applications. It operates from a single or dual power supply of ±3.5 V
(7 V) to ±13 V (26 V). In single-supply operation, the input common-mode range extends
below gr
ound. The OPA564 is easy to heat sink over the specified extended industrial
temperature range, –40°C to +125°C.
