OPA129U General Description
The OPA129U, precision operational amplifier from Texas Instruments, is tailored for high-precision applications with stringent requirements for input offset voltage, input bias current, and noise. It boasts impressive DC performance with a typical input offset voltage of 25μV and a maximum offset voltage drift of 0.15μV/°C, ensuring reliable operation across a wide temperature range. Its single/dual power supply voltage versatility, ranging from ±2.25V to ±18V, makes it adaptable to various circuit configurations. With a high gain-bandwidth product of 10MHz, the OPA129U can effectively handle rapid signal processing tasks, while its high slew rate of 12V/μs enables prompt response to input voltage changes. Furthermore, the op-amp excels in common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR), making it ideal for precision instrumentation and sensor signal conditioning applications. Available in a small outline package (SOIC), the OPA129U facilitates easy integration into circuit designs
