AD8277BRZ

AD8277BRZ 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 op-amps. 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.
