Add To BomOPA129U General Description
The OPA129U is a precision operational amplifier (op-amp) manufactured by Texas Instruments. It's designed for high-precision applications requiring low input offset voltage, low input bias current, and low noise. With a typical input offset voltage of 25μV and a maximum offset voltage drift of 0.15μV/°C, it offers excellent DC performance over a wide temperature range. The OPA129U operates with a single or dual power supply voltage ranging from ±2.25V to ±18V, making it versatile for various circuit configurations. It features a high gain-bandwidth product of 10MHz, enabling it to handle fast signal processing tasks. The op-amp also has a high slew rate of 12V/μs, ensuring it can quickly respond to input voltage changes. Additionally, it offers excellent common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR), making it suitable for precision instrumentation and sensor signal conditioning applications. The OPA129U is available in a small outline package (SOIC) for easy integration into circuit designs
