LM346N Description

Short technical summary and product information.

The LM346N is a programmable quad operational amplifier manufactured by STMicroelectronics. It consists of four independent, high-gain, internally compensated amplifiers that can be programmed for various electrical characteristics using external resistors. The device supports a wide power supply range from ±1.5V to ±22V and features a low supply current of 350 µA per amplifier. Its gain bandwidth product is guaranteed at 1 MHz, with a low noise voltage of 28 nV/√Hz. The device employs a class AB output stage, eliminating crossover distortion, and is suitable for applications such as active filters, instrumentation, and signal conditioning. It is available in a dual-in-line package with a typical package code of J16A. The device complies with RoHS3 standards, is unaffected by REACH regulations, and has a moisture sensitivity level of 1.
