The OP291GSZ is an operational amplifier (Op Amp) RRIO SGL SUPPLY MICROPOWER IC designed and manufactured by Analog Devices. It is a single, low-noise, high-input impedance, rail-to-rail output, low-power, voltage feedback device designed to operate from a single low-voltage power supply up toSupply +5V.The OP291GSZ features a low-noise figure of 4.5 nV/vHz, wide bandwidth of 250 kHz, high power supply rejection ratio of 55 dB, and high-common mode rejection ratio of 80 dB. Its adjustable input common mode range makes it well suited for applications with wide input range.The OP291GSZ is used in a variety of applications, including signal conditioning, battery monitoring, signal processing, communication, medical equipment, instrumentation, automotive, and more. Its rail-to-rail output allows it to scale large input signals without the risk of saturation, while its high precision performance and low power consumption make it suitable for power-sensitive applications. Its small size and wide temperature range make it suitable for a variety of design requirements.
