 输入电压。这会在
A1和A2的输出由增益（2RF/RG+1）给出
乘以输入电压的差分部分。团结
增益减法器A3从
产生单端输出VOUT的输出电压，称为
参考引脚处的电位。
RG值是输入前置放大器级跨导的决定因素。由于RG减小为较大值
增益跨导增加。这有三点很重要
优势。首先，这种方法允许电路实现
非常高的开环增益（3×108
以编程增益≥ 500)
从而减少与增益相关的误差。第二，增益带宽
由C3、C4和输入跨导决定的乘积随增益增加而增加，从而优化频率
回答第三，输入电压噪声降低到一个值
由输入晶体管的集电极电流决定
（4毫伏/√赫兹）。
输入保护
差分输入放大器经常遇到输入电压
超出其线性操作范围。在为AD625应用输入保护时，有两个注意事项；1） 那个
连续输入电流必须限制在10 mA以下
和2）输入电压不得超过
一个以上的二极管压降（25°C时约0.6 V）。
在差动过载条件下，存在（RG+100）Ω 在里面
串联，在
正负输入，任意方向。无外部保护，RG非常小（即40Ω), 大过载
AD625可以持 puts of A1 and A2 forces the collector currents of Q1–Q4 to be constant, thereby, impressing the
input voltage across RG. This creates a differential voltage at the
outputs of A1 and A2 which is given by the gain (2RF/RG + 1)
times the differential portion of the input voltage. The unity
gain subtracter, A3, removes any common-mode signal from the
output voltage yielding a single ended output, VOUT, referred to
the potential at the reference pin.
The value of RG is the determining factor of the transconductance of the input preamp stage. As RG is reduced for larger
gains the transconductance increases. This has three important
advantages. First, this approach allows the circuit to achieve a
very high open-loop gain of (3 × 108
 at programmed gains ≥ 500)
thus reducing gain related errors. Second, the gain-bandwidth
product, which is determined by C3, C4, and the input transconductance, increases with gain, thereby, optimizing frequency
response. Third, the input voltage noise is reduced to a value
determined by the collector current of the input transistors
(4 nV/√Hz).
INPUT PROTECTION
Differential input amplifiers frequently encounter input voltages
outside of their linear range of operation. There are two considerations when applying input protection for the AD625; 1) that
continuous input current must be limited to less than 10 mA
and 2) that input voltages must not exceed either supply by
more than one diode drop (approximately 0.6 V @ 25°C).
Under differential overload conditions there is (RG + 100) Ω in
series with two diode drops (approximately 1.2 V) betw
