Describe：OPA2188AIDR is a dual-channel, high-precision, zero-drift operational amplifier launched by Texas Instruments. It adopts an SOIC-8 surface mount packaging. This device is designed based on TI's proprietary automatic zeroing technology and features rail-to-rail output and EMI filtering characteristics. It is specifically optimized for precise measurement applications that require extremely low offset voltage and low drift. The key features of this operational amplifier include: The zero-drift architecture ensures that the offset voltage temperature drift is as low as 0.03 µV/°C, with the maximum offset voltage being only 25 µV (typical value 6 µV). It can maintain high accuracy over a long period without requiring system-level calibration. Its gain bandwidth product is 2 MHz, the slew rate is 0.8 V/µs, and the typical static current per channel is only 415 µA, balancing accuracy and power consumption. This device is powered by a single 4V to 36V supply or a dual ±2V to ±18V supply. The common-mode rejection ratio is as high as 146dB, the open-loop gain is 136dB, and the input bias current is only 160pA. The integrated EMI filtering function can effectively suppress radio frequency interference such as from wireless communication. The operating temperature range is from -40°C to +105°C, making it suitable for industrial-grade precision measurement and data acquisition systems.
