QW-R107-019,B
20W AUDIO POWER AMPLIFIER
DESCRIPTION
The UTC LM1875 is a monolithic power amplifier offering
very low distortion and high quality performance for
consumer audio applications.
The UTC LM1875 delivers 20 wants into a 4Ω or 8Ω load
on +25V supplies.Using an 8 Ω
load and +30V
supplies,over 30 watts of power may be delivered.The
amplifier is designed to operate with a minimum ofexternal
components.Device overload protection consists of both
internal current limit and thernal shutdown.
The UTC 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.
FEATURES
*Up to 30 watts output power
