AD8279BRZ

AD8279BRZ is a general-purpose difference amplifier. It is intended for precision signal conditioning in power critical applications that require both high performance and low power. It provides exceptional common mode rejection ratio (80dB) and high bandwidth while amplifying input signals that are well beyond the supply rails. The on-chip resistors are laser trimmed for excellent gain accuracy and high CMRR. They also have extremely low gain drift vs. temperature. The common-mode range of the amplifier extends to almost triple the supply voltage (for G = ½), making the amplifier ideal for single-supply applications that require a high common mode voltage range. The internal resistors and ESD circuitry at the inputs also provide overvoltage protection to the op-amp. It is widely used in application such as voltage measurement and monitoring, current measurement and monitoring, instrumentation amplifier building block, portable, battery-powered equipment, test and measurement etc.
