Swappable dual DIP type OPAMP upgrades ultimate digital surround sound.

热插拔的双部型运放升级最终数字环绕音效。

The cascade current mirror was used in the circuit, and the output of the OPAMP was used for the bias of itself and to drive the next stage.

其设计特点是采用了共源共栅电流镜，运放的输出作为驱动的同时还作为自身的偏置电路；其次是采用了带隙温度补偿技术。

A digital automatic calibration technique is developed to trim the differential OPAMP s input-referred and its former output stage offset voltages.

通过一种数字自动校准技术，可以校准差分运放及其输入信号所产生的失调电压。

Hardware circuit Design: 89c51 minimum system together with the mold and mold into the circuit ADC0809 circuit TLC7528 OPAMP posed by the charged object. 2.

硬件电路设计：89c51最小系统加上模入电路adc 0809和模出电路TLC7528；由运放构成的被控对象。
