Overview
The LM833DT is a monolithic dual operational amplifier produced by STMicroelectronics. It is particularly well-suited for audio applications due to its low voltage noise and high-frequency performance. The LM833DT offers a low voltage noise of 4.5 nV/√Hz and a high gain bandwidth product of 15 MHz, along with a high slew rate of 7 V/µs. Additionally, it features very low distortion (0.002%) and excellent phase/gain margins, making it an ideal choice for various audio and preamplification tasks.
