A single reference voltage generation source should be shared by all ADC modules. This will minimize reference voltage mismatch between ADC modules. The reference voltage should then be buffered by a precision
op-amp with good bandwidth and low output impedance before being driven into the reference pin
请问 op-amp的放大器是否是必须的。如果经过Voltage Reference线性稳压器输出的电压不经过OP-amp直接进入DSP的ADC模块是否可以？ 和加了OP-amp有什么区别。
