OP291GSZ General Description

OP291GSZ is an operational amplifier (op-amp) manufactured by Analog Devices. It's a low-voltage, low-power, single-supply precision operational amplifier. With a supply voltage range of 1.8V to 5.5V, it's suitable for battery-powered applications and portable devices. The OP291GSZ offers a low input offset voltage of 250µV, ensuring accurate signal processing in precision measurement systems and sensor interfaces. It features a low input bias current of 50pA, reducing errors in high-impedance sensor applications. This op-amp also provides rail-to-rail output swing, enabling it to operate close to both supply rails, maximizing dynamic range. It has a unity-gain bandwidth of 6.5MHz and a slew rate of 2V/µs, facilitating fast response times in signal conditioning circuits. The OP291GSZ is available in a small SOT-23 package, making it suitable for space-constrained applications.
