The OPA228U is a high precision, low noise operational amplifier from Texas Instruments, designed for applications requiring both AC and precision DC performance. It features a low noise density of 3 nV/,àöHz and a wide bandwidth of 33 MHz, with a high slew rate of 10 V/Oºs, making it suitable for high-speed applications. The amplifier has a high common-mode rejection ratio (CMRR) of 138 dB and an open-loop gain of 160 dB, ensuring accurate signal amplification. It operates with a low input bias current of 10 nA maximum and a low offset voltage of 75 ¬µV maximum, which enhances its precision in sensitive applications. The OPA228U supports a wide supply range from ¬±2.5 V to ¬±18 V and is available in both DIP-8 and SO-8 packages. This operational amplifier is ideal for use in data acquisition systems, professional audio equipment, and industrial monitoring applications.
