SLOS481B – JULY 2010 – REVISED OCTOBER 2014

LM833 Dual High-Speed Audio Operational Amplifier

1 Features

3 Description

The LM833 device is a dual operational amplifier with

1

•

Dual-Supply Operation: ±5 V to ±18 V

high-performance specifications for use in quality

•

Low Noise Voltage: 4.5 nV/

√Hz

audio and data-signal applications. Dual amplifiers

•

Low Input Offset Voltage: 0.15 mV

are utilized widely in audio circuits optimized for all

preamp and high level stages in PCM and HiFi

•

Low Total Harmonic Distortion: 0.002%

systems. The LM833 device is pin-for-pin compatible

•

High Slew Rate: 7 V/

μs

with industry-standard dual operation amplifiers. With

•

High-Gain Bandwidth Product: 16 MHz

addition of a preamplifier, the gain of the power stage

can be greatly reduced to improve performance.

•

High Open-Loop AC Gain: 800 at 20 kHz

•

Large Output-Voltage Swing: –14.6 V to 14.1 V
