The LM321 with SOT-23-5L Operational Amplifier ROHS is a low-power, wide-bandwidth, rail-to-rail operational amplifier manufactured by HXY MOS. It has two independent high-gain-bandwidth amplifiers, with low distortion, low offset voltage, low power consumption, and rail-to-rail input and output. It has an operating supply voltage from 2.2V to 5.5V, low supply current (50nA), wide bandwidth (3.2 MHz), and a slew rate of 0.6 V/µs. The output can swing close to the supply rails and can provide up to ±12V of output swing, making it suitable for use in battery-powered systems. It is also RoHS compliant and available in a small SOT-23-5L package with a 0.3mm×0.6mm pitch making it ideal for applications with space constraints.
