The MCP6291IDBVR is a 1-channel, 10-MHz, low-noise, RRIO operational amplifier manufactured by Texas Instruments. This amplifier has an extended temperature range of -40 to 125 degrees Celsius, and is housed in a 5-pin SOT-23 package. It has a 1.6 V to 5.5 V power supply range along with low quiescent current operation at both common-mode and normal mode levels of 7.5 µA and 12 µA respectively, making it suitable for battery-operated applications. The high gain-bandwidth product of 10 MHz, low noise of 9.5 nV/vHz, and input-level noise of 23 nA/vHz further help this amplifier achieve excellent performance and accuracy. This amplifier also features a low-power shutdown mode, reducing the power consumption to 400 nA. The MCP6291IDBVR is an ideal solution for designs requiring low-noise, high-accuracy, and low-drift operational amplifiers.
