Analog Devices Inc. AD8276/AD8277单位增益差分放大器
Analog Devices AD8276/AD8277放大器是通用型单位增益差分放大器，用于在要求高性能、低功耗的功耗关键型应用中实现精密信号调理。 AD8276/AD8277放大器的片内电阻经过激光调整，可实现出色的增益精度和高共模抑制比(CMRR)。 这些放大器采用2V至36V单电源或±2V至±18V双电源供电。 AD8276/AD8277放大器不仅提供极为出色的86dB共模抑制比(CMRR)和550kHZ高带宽，而且可将信号放大至供电轨以外。 这些放大器的CMRR比电源电压的两倍还大，因此非常适合要求高共模电压范围的单电源应用。 这两款放大器的每通道最大静态电源电流为200μA，非常适合用于电池供电和便携式系统。 设计人员还可将这些单位增益稳定差分放大器用于高精度、单端配置（增益为 -1、+1、+2）中。
Analog Devices Inc. AD8276/AD8277 amplifiers deliver an exceptional 86dB common-mode rejection ratio (CMRR) and high bandwidth of 550kHz while amplifying signals that extend beyond the supply rails. Because the CMRR extends more than double the supply voltage, the amplifiers are well-suited for single-supply applications requiring a high common-mode voltage range. With a maximum quiescent supply current of 200μA per channel, the amplifiers are ideal for battery-operated and portable systems. The designers can also connect these unity-gain stable difference amplifiers in high precision, single-ended configurations with G = −1, +1, +2.
