SGM8251中文资料2.8MHz, High Voltage, High Precision, Low Noise Rail-to-Rail Output Operational Amplifier数据手册SGMICRO规格书

描述 Description

The SGM8251 is a single, low noise and high precision operational amplifier optimized for high voltage operation from 4.5V to 36V single supply. The device provides rail-to-rail output operation.
The SGM8251 offers a low offset voltage less than 18μV and a low bias current. The combination of characteristics makes the SGM8251 a good choice for temperature measurements, pressure and position sensors, strain gauge amplifiers and medical instrumentation, or any other 4.5V to 36V applications requiring precision and long-term stability.
The SGM8251 is available in Green SOT-23-5, SOIC-8 and MSOP-8 packages. It is rated over the -40℃ to +125℃ temperature range.
