• 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
