AD8277ARZ-R7

AD8277 is a general-purpose, low power, low cost unity-gain difference amplifier. It is used for precision signal conditioning in power critical applications that require both high performance and low power. They provide exceptional 86dB common-mode rejection ratio (CMRR) and high bandwidth while amplifying signals well beyond the supply rails. The on-chip resistors are laser trimmed for gain drift of 1ppm/°C and high CMRR. The common-mode range of the amplifiers extends to almost double the supply voltage, making this amplifier ideal for single-supply applications that require a high common-mode voltage range. The internal resistors and electrostatic discharge (ESD) circuitry at the inputs also provide overvoltage protection to the opamps. This amplifier is widely used in application such as voltage measurement and monitoring, current measurement and monitoring, differential output instrumentation amplifier, portable, battery-powered equipment, test and measurement etc.
