LM246N Description

The LM246N is a general-purpose operational amplifier (op-amp) designed by STMicroelectronics. This IC is housed in a tube package and features a 16-DIP form factor, making it suitable for through-hole mounting. It consists of four independent circuits, each capable of delivering up to 20 mA of output current per channel. The LM246N operates within a wide supply voltage range, from a minimum of 3 V to a maximum of 44 V, ensuring flexibility in various power supply configurations. Its gain bandwidth product is rated at 1 MHz, and it boasts a slew rate of 0.5 V/µs. The input bias current is a low 30 nA, and the input offset voltage is maintained at 500 µV. The supply current for each op-amp is 1 mA. This product is classified as obsolete but remains a valuable component due to its robust performance and compliance with industry standards such as REACH and ROHS3. It also has a moisture sensitivity level (MSL) of 1, indicating it is unaffected by moisture, and is categorized under ECCN EAR99 and HTSUS 8542.33.0001.
