OPA4251UA Description

The OPA4251UA from Texas Instruments is a quad-channel, general-purpose operational amplifier from the microPOWER™ series, designed for precision low-power applications. Packaged in a 14-SOIC tube, it operates over a wide supply voltage range (2.7V to 36V), making it versatile for both battery-powered and industrial systems. With an ultra-low input bias current of 20 nA and a minimal input offset voltage of 100 µV, it ensures high accuracy in signal conditioning. The 35 kHz gain bandwidth product (GBW) and 0.01V/µs slew rate optimize it for low-frequency, low-noise applications.

OPA4251UA Features

• Ultra-Low Power Consumption: Ideal for battery-operated devices due to microPOWER™ technology.
• High Voltage Tolerance: Supports up to 36V supply, suitable for industrial and automotive environments.
• Low Input Bias Current (20 nA): Minimizes errors in high-impedance sensor interfaces.
• Quad-Channel Integration: Four independent op-amps in a compact 14-SOIC package, reducing board space.
• Robust Performance: ROHS3 compliant and REACH unaffected, ensuring environmental and regulatory compliance.
• Stable Operation: MSL 3 (168 hours) moisture sensitivity ensures reliability in humid conditions.
