OPA227U

OPA227U Description

The OPA227U from Texas Instruments is a high-precision, general-purpose operational amplifier (op-amp) designed for demanding analog signal conditioning applications. Housed in an 8-SOIC package, this single-channel op-amp delivers exceptional DC precision with an ultra-low input offset voltage of 5 µV and minimal input bias current of 2.5 nA. Its wide supply voltage range (5V to 36V) and robust output current capability (45 mA per channel) make it suitable for industrial, medical, and test/measurement systems requiring high accuracy and stability.

OPA227U Features

• Ultra-Low Offset Voltage (5 µV): Ensures high DC accuracy in precision instrumentation.
• Low Input Bias Current (2.5 nA): Minimizes errors in high-impedance sensor interfaces.
• High Gain Bandwidth (8 MHz) & Slew Rate (2.3V/µs): Supports fast signal processing with minimal distortion.
• Wide Supply Range (5V–36V): Flexible for both low-power and high-voltage designs.
• Low Supply Current (3.7mA): Balances performance and power efficiency.
• RoHS3 & REACH Compliant: Meets environmental and regulatory standards.
• MSL 2 (1 Year): Ensures reliability in moisture-sensitive applications.
