DESCRIPTION
The LM1875 is a monolithic power amplifier offering
very low distortion and high quality performance for
consumer audio applications.
The LM1875 delivers 20 watts into a 4Ω or 8Ω load
on ±25V supplies. Using an 8Ω load and ±30V
supplies, over 30 watts of power may be delivered.
The amplifier is designed to operate with a minimum
of external components. Device overload protection
consists of both internal current limit and thermal
shutdown.
The LM1875 design takes advantage of advanced
circuit techniques and processing to achieve
extremely low distortion levels even at high output
power levels. Other outstanding features include high
gain, fast slew rate and a wide power bandwidth,
large output voltage swing, high current capability, and a very wide supply range. The amplifier is
internally compensated and stable for gains of 10 or
greater.
