Audio dual op-amp with 15 MHz GBW and 7 V/µs slew rate
Designed for audio signal conditioning, it operates from a split or single supply spanning 10 V to 30 V, drawing 5 mA per channel.
Supply current and output drive for multi-channel designs
Each of the two amplifiers draws 5 mA quiescent current, totalling 10 mA for the package. In a four-op-amp design using two LM833MX/NOPB devices, the supply budget hits 20 mA before any load — worth accounting for in low-power audio codecs or battery-powered portable gear. Output current per channel is rated at 40 mA, enough to drive a 600 Ω headphone load or feed a line-level output transformer directly.
Input offset and bias — what they mean for DC accuracy
Input offset voltage is specified at 300 µV, and input bias current at 500 nA. For AC-coupled audio stages these numbers are irrelevant — the coupling capacitors block DC offsets. But in DC servo loops or single-supply bias networks, 300 µV offset times the closed-loop gain can shift the output operating point. The 500 nA bias current matters when the source impedance is high (above 10 kΩ), where it develops a voltage drop that adds to the offset.
