采样／保持放大器（SHA）的采集时间是指从采样命令发出到输出电压能在给定的误差带内（一般为满量程输入的±0．1％或土0．01％）跟踪输入电压的最小时间．它反映了SHA由保持状态向采样状态跃变阶段的动态性能．经过采集时间后，SHA的输出才可以认为等于输入电压，因此采集时?
The sample / hold amplifier (SHA) acquisition time refers to the time it takes for the sample command to be sent to the output voltage to track the input voltage within a given error band (typically ± 0.1% or 0.01% of full scale input) The minimum time. It reflects the dynamic performance of the SHA from the hold state to the sampling state transition phase. After the acquisition time, SHA output can be considered equal to the input voltage, so when collecting?
