相对于运算放大器，AD8138在差分信号处理方面取得了重大进步。AD8138可以用作单端至差分放大器或差分至差分放大器。它像运算放大器一样易于使用，并且大大简化了差分信号放大与驱动。该器件采用ADI公司的专有XFCB双极性工艺制造，-3 dB带宽为320 MHz，提供差分信号，谐波失真在现有差分放大器中最低。AD8138具有独特的内部反馈特性，可以提供输出增益和相位匹配平衡，从而抑制偶数阶谐波。内部反馈电路则可以使外部增益设置电阻不匹配的任何相关增益误差最小。

AD8138的差分输出有助于平衡差分ADC的输入，使ADC性能达到最高。该器件无需使用具有高性能ADC的变压器，并保留低频和直流信息。在V_OCM 引脚上施加电压便可调整差分输出的共模电平，从而使驱动单电源ADC的输入信号可轻松实现电平转换。快速过载恢复则可确保采样精度。

AD8638是一款宽带宽、自动调零的放大器，采用5V～16V单电源或者±2.5V～±8V双电源供电。这款零漂移放大器采用亚德诺公司最新拓扑结构，实现了高精度、低成本、低噪声的完美结合。AD8638系列产品大大降低了数字开关噪声，这种噪声在斩波稳定放大器中已经司空见惯。AD8638失调电压10µV，失调漂移小于0.08µV/°C，噪声仅为1.5µVp-p(0Hz ～10Hz)，该系列产品非常适合误差源必须最小化的应用。接近零漂移的性能使位置与压力传感器、热电堆探测器、医疗设备以及应变计放大器在整个工作温度范围时受益匪浅。AD8638系列放大器工作温度范围是：-40°C～+125°C。AD8638采用SOT-23封装以及SOIC封装。 More

The OP07D is a low cost option of the OP07 family with voltage offset performance of 150 µV max. The OP07D is a precision, ultralow offset amplifier. It integrates low power (1.1 mA typical), low input bias current (±1 nA maximum), and high CMRR/PSRR (130 dB). Operation is fully specified from ±5 V to ±15 V supply.

The OP177 features one of the highest precision performance of any op amp currently available. Offset voltage of the OP177 is only 25 μV maximum at room temperature. The ultralow VOS of the OP177 combines with its exceptional offset voltage drift (TCVOS) of 0.1 μV/°C maximum to eliminate the need for external VOS adjustment and increases system accuracy over temperature.
