HIGH OUTPUT CURRENT: 1.5A

•

WIDE POWER-SUPPLY RANGE:

The OPA564 is a low-cost, high-current operational

amplifier that is ideal for driving up to 1.5A into

– Single Supply: +7V to +24V

reactive loads. The high slew rate provides 1.3MHz

– Dual Supply: ±3.5V to ±12V

full-power bandwidth and excellent linearity. These
