LM831 Low Voltage Audio Power Amplifier
General Description
The LM831 is a dual audio power amplifier optimized for
very low voltage operation. The LM831 has two indepen-
dent amplifiers, giving stereo or higher power bridge (BTL)
operation from two- or three-cell power supplies.
The LM831 uses a patented compensation technique to re-
duce high-frequency radiation for optimum performance in
AM radio applications. This compensation also results in
lower distortion and less wide-band noise.
The input is direct-coupled to the LM831, eliminating the
usual coupling capacitor. Voltage gain is adjustable with a
single resistor.
