如何使用Rail-to-Rail 放大器 来提高输入偏置精度 Application Note 1683 Author: Tamara Schmitz How to use Rail-to-Rail Amplifiers to Improve Input Offset Accuracy In today's electronic systems, the negative power supply is disappearing, while the positive power supply voltage is decreasing. This trend is driving the proliferation of rail-to-rail amplifiers. While the supply voltage is changing, the signal level often remains the same. For example, the standard video signal is 2V. When the power supply comes down to 2V, the amplifier/buffer must be linear or accurate within the full 2V supply……
