OPA2197ID

OPA2197ID Description

The OPA2197ID from Texas Instruments is a high-performance, dual-channel general-purpose operational amplifier (op-amp) designed for precision and high-speed applications. Packaged in an 8-SOIC tube, this IC operates over a wide supply voltage range of 4.5V to 36V, making it versatile for industrial, automotive, and instrumentation systems. With an ultra-low input bias current of 5 pA and a minimal input offset voltage of 25 µV, it ensures high accuracy in signal conditioning and sensor interfacing. The ROHS3 Compliant and REACH Unaffected certifications further enhance its suitability for environmentally sensitive applications.

OPA2197ID Features

• High Gain Bandwidth (10 MHz): Enables stable operation in high-frequency signal chains.
• Fast Slew Rate (20V/µs): Ideal for rapid signal transitions in data acquisition and control systems.
• Low Power Consumption: Dual-channel operation at 1mA per channel, balancing performance and efficiency.
• High Output Current (65 mA/channel): Drives heavy loads without external buffering.
• Wide Supply Range (4.5V–36V): Supports both low-voltage and industrial-level designs.
• Low Input Bias Current (5 pA): Minimizes errors in high-impedance circuits.
• Robust Packaging (8-SOIC): Ensures reliability in surface-mount applications with MSL 2 (1 Year) moisture sensitivity.
