Another limitation on this circuit is that the output resistance is defined by R1, which needs to be at least a few hundred ohms in order to limit the output of current in the op amp output. Some ADCs need to be driven by a low resistance so buffer amp U3 might be r...

The overexpression of AnxA2 in breast cancer has been shown to be capable of modulating key events in tumour progression; mainly those involving proliferation, adhesion, migration, invasion, angiogenesis, and drug resistance (Ling et al, 2004; Rescher and Gerke, 2004; Sharma and Sharma, 2007; ...

aIn this configuration, the negative rail is generated simply with an inverting amplifier with a gain of −1. A low offset op amp should be used to minimize the voltage error at the negative output. 在这种配置,消极路轨用一个倒置的放大器简单地引起以−1获取。 应该用于一低垂距操作安培使电...

The minimum resistance values are limited by the output drive capabilities of the DAC and reference output. The accuracy of the output transfer function is heavily dependent on the accuracy of the resistor ratios. High-accuracy resistors are recommended. DC Transfer Characteristics The following ...
