AD620的低误差归因于两个来源，
输入和输出错误。输入时，输出误差除以G。在实践中，输入误差占主导地位
并且输出误差在低增益时占主导。这个
给定增益的总VOS计算如下：
总误差RTI=输入误差+（输出误差/G）
总误差RTO=（输入误差×G）+输出误差
参考终端
参考端子电位定义了零输出电压，当负载与系统其他部分不共享接地时尤其有用。它提供了一种直接向输出注入偏移的方法，在电源电压范围内允许2V。寄生电阻应为小值，以获得佳CMR。
输入保护AD620可安全承受±60 mA的输入电流：
在室温下几个小时。这适用于所有增益和通电和断电，如果信号源和放大器单独供电，这很有用。对于较长时间段，输入电流不应超过6 mA。
对于电源以外的输入电压，保护电阻器
应与每个输入串联，以限制当前tomA。这些电阻器可以与RFIfilter中使用的电阻器相同。高电阻值会影响系统的噪声和ACCMRR性能。低泄漏二极管（如BAV199）可采用pla /°C—for the best performance.Table 5. Required Values of Gain Resistors1% Std TableValue of RG(Ω)CalculatedGain0.1% Std TableValue of RG(Ω )CalculatedGain49.9 k 1.990 49.3 k 2.002

The low errors of the AD620 are attributed to two sources,
input and output errors. The output error is divided by G whenreferred to the input. In practice, the input errors dominate at
high gains, and the output errors dominate at low gains. The
total VOS for a given gain is calculated as
Total Error RTI = input error + (output error/G)
Total Error RTO = (input error × G) + output error
REFERENCE TERMINAL
The reference terminal potential defines the zero output voltageand is especially useful when the load does not share a preciseground with the rest of the system. It provides a direct means ofinjecting a precise offset to the output, with an allowable rangeof 2 V within the supply voltages. Parasitic resistance should bekept to a minimum for optimum CMR.
INPUT PROTECTIONThe AD620 safely withstands an input current of ±60 mA for
several hours at room temperature. This is true for all gains andpower on and off, which is useful if the signal source andamplifier are powered separately. For longer time periods, theinput current should not exceed 6 mA.
For input voltages beyond the supplies, a protection resistor
should be placed in series with each input to limit the current tomA. These can be the same resistors as those used in the RFIfilter. High values of resistance can impact the noise and ACCMRR performance of the system. Low leakage diodes (such asthe BAV199) can be pla
