Frequently Asked Questions
What is the maximum supply voltage of the OPA551UA?
The OPA551UA supports a maximum supply voltage of +-30V (60V total), making it ideal for high-voltage analog signal conditioning and industrial applications requiring wide voltage rails.
What output current can the OPA551UA deliver?
The OPA551UA can continuously source or sink up to 200mA of output current, enabling it to directly drive capacitive loads, piezoelectric actuators, and low-impedance circuits without external buffer stages.
What package is the OPA551UA and how many pins does it have?
The OPA551UA is housed in an 8-pin SOIC (Small Outline IC) package. The UA suffix designates the plastic SOIC-8 variant, suitable for standard PCB assembly with 1.27mm pitch leads.
What are common alternatives to the OPA551UA?
Common alternatives include the OPA544 (higher current, TO-220 package), OPA452 (similar voltage range, wider bandwidth), and LM675 (general-purpose power op-amp). Choose based on required output current, supply voltage, and package constraints.
Is the OPA551UA RoHS compliant?
Yes, the OPA551UA is RoHS compliant and lead-free. It meets EU Directive 2011/65/EU and is suitable for use in environmentally regulated end products in industrial and consumer electronics markets.
