OP07C中文资料

OP07C中文资料

OP07C中文资料一、Op07芯片是一种低噪声，非斩波稳零的单运算放大器集成电路。

由于OP07具有非常低的输入失调电压（对于OP07A最大为25μV），所以OP07在很多应用场合不需要额外的调零措施。

OP07同时具有输入偏置电流低（OP07A为±2nA）和开环增益高（对于OP07A 为300V/mV）的特点，这种低失调、高开环增益的特性使得OP07特别适用于高增益的测量设备和放大传感器的微弱信号等方面。

二、OP07特点：超低偏移： 150μV最大。

低输入偏置电流： 1.8nA 。

低失调电压漂移： 0.5μV/℃。

超稳定，时间： 2μV/month最大高电源电压范围：±3V至±22V三、OP07内部结构原理图四、OP07芯片引脚功能说明：1和8为偏置平衡(调零端)，2为反向输入端，3为正向输入端，4接地，5空脚 6为输出，7接电源+ABSOLUTE MAXIMUM RATINGS 最大额定值五、OP07典型应用电路图4 输入失调电压调零电路图5 典型的偏置电压试验电路图6 老化电路图7 典型的低频噪声放大电路图8 高速综合放大器图9 选择偏移零电路图10 调整精度放大器图11高稳定性的热电偶放大器图12 精密绝对值电路op07的功能介绍：Op07芯片是一种低噪声，非斩波稳零的双极性运算放大器集成电路。

由于OP07具有非常低的输入失调电压（对于OP07A 最大为25μV），所以OP07在很多应用场合不需要额外的调零措施。

OP07同时具有输入偏置电流低（OP07A为±2nA）和开环增益高（对于OP07A为300V/mV）的特点，这种低失调、高开环增益的特性使得OP07特别适用于高增益的测量设备和放大传感器的微弱信号等方面。

特点：超低偏移： 150μV最大。

低输入偏置电流： 1.8nA 。

低失调电压漂移： 0.5μV/℃。

超稳定，时间： 2μV/month最大高电源电压范围：±3V至±22V工作电源电压范围是±3V~±18V；OP07完全可以用单电源供电，你说的＋5V,-5V绝对没有问题，用单＋5V也可以供电，但是线性区间太小，单电源供电，模拟地在1/2 VCC. 建议电源最好>8V，否则线性区实在太小，放大倍数无法做大，一不小心，就充顶饱和了。
