 p的漂移规格。
输入和输出偏移电压
偏移电压规格通常被视为
仪表放大器的优点。而初始偏移可能是
调整为零,偏移电压因温度而变化
变化会导致错误。智能系统通常可以纠正
对于具有自动归零周期的该因子,但这需要额外的
电路。偏移电压和偏移电压漂移各有两个分量:输入和输出。输入偏移量是偏移量的分量
在输入阶段生成。在输出端测量
与增益成正比,即在
G=100时的输出比在
G=1。输出偏移在输出处生成,并且是恒定的
为了所有利益。
输入偏移和漂移乘以增益,而
输出项与增益无关,因此输入误差
高增益时占主导地位,低增益时输出误差占主导地位。
输出偏移电压(和漂移)通常指定为
G=1(输入影响不显著),而输入偏移
(和漂移)在高增益下给出(输出效应可以忽略不计)。所有输入相关参数均参考
输入(RTI),即对输出的影响为“G”
倍大。偏移电压与电源也规定为通过分离这些误差,可以独立于增益评估总误差。对于给定的增益,两个误差可以组合起来,得到输入(RTI)或输出的总误差
(RTO)采用以下公式:
总误差RTI=输入误差+(输出误差/增益)
总误差RTO=(增益×输入误差)+输出误差
AD625提供输入和输出偏移电压
调整这简化了非常高精度应用中的零点,并将开关增益中的偏移电压影响降至低
应用。在这种应用中,输入偏移量被调整
首先在高编程增益,然后输出偏移为
调整为G=1。如果只需要一个空值,则输入偏移量
应使用null。仅使用时的大附加漂移
输入偏移零点为0.9µV/°C,RTO

  is determined by C3, C4, and the input transconductance, increases with gain, thereby, optimizing frequency
response. T The diodes to the supplies are only necessary if input voltages
outside of the range of the supplies are encountered. In higher
gain applications where differential voltages are small, back-toback Zener diodes and smaller resistors, as shown in Figure
26b Any resistors in series with the inputs of the AD625 will degradethe noise performance. For this reason the circuit in Figure 26bshould be  By establishing a reference at the “low” side of a current setting
resistor, an output current may be defined as a function of input
v Offset voltage and offset voltage drift each have two components: input and output. Input offset is that component of offset
that is generated at the input stage. Measured at the output it is
directly proportional to gain, i.e., input offset as measured at the
output at G = 100 is 100 times greater than that measured at
G = 1. Output offset is generated at the output and is constant
for all gains.
 ffset voltage (and drift) is normally specified atBy separating these errors, one can evaluate the total error independent of the gain. For a given gain, both errors can be combined to give a total error referred to the input (RTI) or output
(RTO) by the following formula:
Total Error RTI = input error + (output error/gain)
Total Error RTO = (Gain × input error) + output error
The AD625 provides for both input and output offset voltage
adjustment. This simplifies nulling in very high precision applications and minimizes offset voltage effects in switched gain
applications. In such applications the input offset is adjusted
first at the highest programmed gain, then the output offset is
adjusted at G = 1. If only a single null is desired, the input offset
null should be used. The most additional drift when using only
the input offset null is 0.9 µV/°C, RTO
