LM18298T-LM1830N
Dual Full-Bridge Driver
LM1875
20W Audio Power Amplifier
General DescriptionThe LM1875isa monolithic power amplifier offering verylow
distortionand high quality performancefor consumer audio
applications.
The LM1875 delivers20 wattsintoa4Ωor8Ω loadon ±25V
supplies. Usingan8Ω load and ±30V supplies, over30
wattsof power maybe delivered.The amplifieris designed operate witha minimumof external components. Device
overload protection consistsof both internal current limitand
thermal shutdown.
The LM1875 design takes advantageof advanced circuit
techniquesand processingto achieve extremelylow distor-
tion levels evenat high output power levels. Other outstand-
ing features include high gain,fast slew rate anda wide
power bandwidth, large output voltage swing, high current
capability,anda very wide supply range.The amplifierisin-
ternally compensatedand stablefor gainsof10or greater.
FeaturesUpto30 watts output power AVO typically90dB Low distortion: 0.015%,1 kHz,20W Wide power bandwidth:70kHz ProtectionforACandDC short circuitsto ground Thermal protection with parole circuit High current capability:4A Wide supply range 16V-60V Internal output protection diodes94dB ripple rejection Plastic power package TO-220
Applications High performance audio systems Bridge amplifiers Stereo phonographs Servo amplifiers Instrument systems
