评估模块, 用于PGA281零漂移, 高电压可编程增益放大器
The provides basic functional evaluation of the PGA281, a high precision instrumentation amplifier with pin programmable gain, attenuation, and error detection. The PGA281 offers low offset voltage, near zero drift, and very low 1/f noise for high-resolution, precision measurement. The high supply voltage and excellent common mode rejection comply with the requirements for universal industrial signal front ends.
