PENGUAT OP-AMP (LM 741)

Penguat membalik

Penguat Op-Amp membalik akan menguatkan tegangan pada masukan serta membalik hasil penguatan tersebut, jadi keluaran dari rangkaian ini akan selalu memiliki polaritas yang berlawananan dengan sinyal masukannya.

Penguatan tegangan pada rangkaian ini di tentukan menurut

Tegangan keluaran diperoleh dengan jalan mengalikan tegangan masukan yang diketahui dengan factor penguatan, atau

Tanda minus diabaikan dalam perhitungan karna hanya menunjukkan bahwa keluaran berlawanan fasa terhadap masukannya.


Penguat tak membalik

Dalam konfigurasi ini umpan balik yang digunakan untuk mengatur penguatan tetap di berikan pada masukan membalik, tapi Vin di berikan pada masukan tak membalik sehingga tegangan keluaran akan selalu sefasa dengan tegangan masukannya.

Untuk mendapatkan penguatan tegangan dapat dicari dengan persamaan berikut

Untuk memperoleh tegangan keluaran dapat dicari dengan mengalikan tegangan masukan yang diketahui dengan factor penguatan, atau


Penguat penjumlah tegangan

Dengan menggunakan rangkaian penguat membalik dasar dan menambahkan resistor pada masukan lainnya, kita dapat membuat penguat penjumlah membalik. Tegangan keluaran akan dibalik dan nilainya sama dengan penjumlahan aljabar dari masing-masing perkalian tegangan masukan dengan hasil bagi resistor masukan dengan resistor umpan balik yang bersesuaian, atau dapat dinyatakan sebagai berikut

Suku RF/RN (VN) dalam rumus di atas menyatakan bahwa dalam rangkaian tersebut mungkin terdapat lebih dari dua masukan. Bila semua resistor luar sama nilainya (Rf = R1 = R2 = … = RN), keluaran dapat dengan mudah dapat di hitung sebagai penjumlahan aljabar dari masing-masing tegangan masukan, atau

Rangkaian Power Amplifier

In earlier times the amplifier assembly is the product of the simplest class amplifier. Enthusiasts is the salt of the amplifier can not afford to buy the manufacturer. But this time was different, because the amplifier assembly today its luxury-performance luxury. Even the upscale audiophile many degressive come down to make homemade amplifiers Factors that support the rapid development of this amplifier is assembled, because today we are able to buy electronic components high-end class, the electronics shops nearby. Also this time have many amplifiers appear builder experienced elbow.

To make a good amplifier assembly, components best use is not the only measure, which is more important than that is a builder who used it. Many people mistakenly think in assembling, they think that using the the best components entirely the result must be the best too. Do-think like that often do not get a satisfactory result assembly. To get the maximum assembly required an experienced builder.

An experienced builder to make the amplifier like a chef cooking process, he mixed all the components of the reply to the cheap cost of good to bad all stirred together until the dough is created by the outcome of a dainty for the listener's ears. Where is the bass voice was soft and melodic, treble voice sounded like sticky rice crispy, and the singers vocals sound round and delicious
