The simple op amp clipper shown in Figure 1 prevents these problems. The maximum allowable input voltage is applied to the non inverting input of U1, and the output is fed back to the inverting input via small signal diode D1. The ADC’s reference voltage can be used for ...
Five to eight min after IP injection, mice were anesthetized with Isoflurane, and the flanks were shaved with a hair clipper. The IVIS imager (PerkinElmer) was used with mid-bin, and exposure for 5 min. Imaging analyses were performed with Living Image (Version 4.5.4). After genotyping, 6...
图1: LT6015 精准型正压和负压限幅器 图1 所示的简单运放限幅器可防止发生这些问题。可允许的最大输入电压被施加在 U1 的同相输入端,而输出则通过小信号二极管 D1 反馈至反相输入端。ADC 的基准电压可用于限幅基准 (如果它是可用的话)。当输入电压低于基准时,U1 的输出被驱动至正电源轨,而...
