Analog Devices Inc. ADA466x 精密 CMOS 运算放大器

Analog Devices ADA466x精密CMOS运算放大器是双通道、精密、轨到轨输入/输出放大器，针对低功耗、高带宽和宽工作电源电压范围应用进行了优化。ADA466x在电源电压为3.0V、10V和18V时保证具有额定性能。该器件是3.3V、5V、10V、12V和15V单电源以及 ±2.5V、±3.3V和±5V双电源应用的理想选择。它采用ADI公司的DigiTrim®调整专利技术，失调电压非常低。此外，ADA466x的独特设计架构使器件工作在 −VSY + 1.5V至+VSY − 1.5V 共模电压范围时具有出色的电源抑制、共模抑制和失调电压性能。

The ADA466x Amp uses the Analog Devices patented DigiTrim® trimming technique, which achieves low offset voltage. Additionally, the unique design architecture of the ADA466x allows it to have excellent power supply rejection, common-mode rejection, and offset voltage when operating in the common-mode voltage range of −VSY + 1.5V to +VSY − 1.5V.
