The LM321 is a low power operational amplifier (OpAmp) manufactured by Pingjingsemi. It is a SOIC-8 (Small Outline Integrated Circuit) package in a SOT-23-5 arrangement, and is RoHS (Restriction of Hazardous Substances) compliant. The LM321 offers single-supply operation with good rail-to-rail performance, and is available in 5-pin SOT-23-5 packages. This OpAmp features a wide gain bandwidth of 1.6MHz, a low input bias current of 1nA, and a low power supply current of 200µA. It is suitable for high-precision amplifier and gain control applications, where its low power operation and fast response time make it particularly well suited.
