LM1875 20W Audio Power Amplifier

Description
The LM1875 is a monolithic energy firm offering very low distortions and top quality performance for consumer audio programs. The LM1875 provides 20W into a 4Ω or 8Ω fill on ±25V resources. Using an 8Ω fill and ±30V resources, over 30watts of power may be provided. The firm is designed to operate with a minimum of exterior elements. Device overburden protection is made up of both inner present limit and heat shut down. The LM1875 design uses advanced routine techniques and handling to achieve extremely low distortions amounts even at higher result energy amounts. Other excellent features include higher gain, fast number rate and a large energy bandwith, large result current move, higher present capability, and a very large supply range. The firm is inner paid for and constant for profits of 10 or greater
