Description

The LM833 is a monolithic dual operational

amplifier particularly well-suited to audio

applications.

It offers low voltage noise (4.5 nV/√Hz) and high

frequency performances (15 MHz gain bandwidth

product, 7 V/µs slew rate).

In addition, the LM833 has a very low distortion

(0.002%) and excellent phase/gain margins.

Input current (2): Vin driven negative

Input current (3): Vin driven positive above

AMR value

2. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the

collector-base junction of the input PNP transistor becoming forward-biased and thereby acting as input

diode clamp. In addition to this diode action, there is NPN parasitic action on the IC chip. This transistor

action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large

overdrive) for the time during which an input is driven negative.

This is not destructive and normal output is restored for input voltages above -0.3 V.

3. The junction base/substrate of the input PNP transistor polarized in reverse must be protected by a resistor

in series with the inputs to limit the input current to 400 µA max (R = (Vin - 36 V)/400 µA).
