PAM8403 Amplifier Kelas D

Deskripsi

The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N,
allowing it to achieve high-quality sound reproduction. The new
filterless architecture allows the device to drive the speaker directly,
requiring no low-pass output filters, thus saving system cost and PCB
area.
With the same numbers of external components, the efficiency of the
PAM8403 is much better than that of Class-AB cousins. It can extend
the battery life, which makes it well-suited for portable applications.
The PAM8403 is available in SOP-16 package.

Berikut ini adalah sensor temperatur NTC K524 yang ditemukan di Jaya Plaza. Harganya lumayan murah, di bawah Rp 10 ribu.

NTC K524
NTC K524

Pengukuran di temperatur 24 derajat Celcius menghasilkan resistansi 41.6 ohm.

Sensor dihangatkan dengan cara digenggam dengan tangan, hasilnya resistansi turun ke 33 ohm. Temperatur tangan kira-kira sekitar 35 derajat celcius menurut termometer GM320.

Spesifikasi NTC K524 menurut http://en.tdk.eu/tdk-en/176900/products/application-guides/consumer—epcos-brand/home-appliances/ignition-units-for-gas-cookers/ntc-thermistors adalah sebagai berikut:

  • NTC thermistor in molded plastic case with fast-on contacts
  • Plastic material PA6.6-GF30
  • Peak operating temperature up to +175 °C / 1000 hours
  • Modular construction for different mounting situations
  • Variety of R/T characteristics and tolerances
  • Temperature range: –10 … +300 °C
  • Insulation voltage: > 1250 V AC
  • Thermal cooling time constant τa air approx. 30 s

Sensor ini non-linier, sehingga untuk konversi resistansi ke temperatur akan memerlukan software khusus. Cocok untuk percobaan dengan board Arduino Nano.

    PTC C870
    PTC C870

    C870 ini adalah sebuah sensor temperatur PTC (Positive Temperature Coefficient), artinya makin panas maka makin besar resistansinya. Menurut datasheetnya, komponen ini umumnya dipakai sebagai pembatas arus. Mekanismenya adalah arus pada PTC menghasilkan panas, dan panas ini akan menaikkan nilai resistansinya. Jika nilai resistansi tinggi, maka arus yang mengalir akan berkurang.

  5. Apply flux core solder to heated parts, not the soldering tip, and heat it till solder melts and flow freely.    ‘
  6. Don t apply too much solder unnecessarily.

CAUTION
When the power is on, the tip temperature can reach over 300°C CS72°F). Since mishandling may lead to  burns or fire, be sure to comply with the following precautions.

  • Do not touch the tip and the metalic parts near the tip.
  • Do not use the product near flammable items. Unplug when the unit is not in use.
  • Do not warm up the soldering iron with the tip pointing down.
  • Do not use the unit for applications other than soldering.
  • Do not wet the unit or use the unit when your hands are wet.
  • Do not modify the unit. Use only genuine DEKKO replacement parts.
  • Do not shock the unit, or otherwise subject the heating element to severe damage.
  • The soldering process will produce smoke, so make sure the area is well ventilated.
  • Children should be supervised to ensure that they do not play with the DEKKO.

WARNING

  • In order to avoid burns, do not attempt to touch except grip as the unit is hot. And do not leave the unit unattended.
  • Do not attempt to use the unitaround combustible in order to prevent tires.

CARA MENYODER

  1. Bersihkan bagian yang disolder.
  2. Bersihkan ujung solder dan lapisi ujung solder dengan timah.
  3. Panaskan bagian untuk disolder.
  4. Beri timah pada bagian yang telah dipanaskan, bukan ujung solder, panaskan sampai cair dan rata.
  5. Jangan beri terlalu banyak timah.

PERHATIAN
Ketika solder on, ujung solder bisa mencapai temperatur lebih dari 300°C (572*F). Penanganan
yang salah bisa menyebabkan luka bakar dan kebakaran, perhatikan hal-hal berikut:

  • Jangan sentuh ujung dan bagian metal dekat ujung.
  • Jangan digunakan dekat bahan yang mudah terbakar cabut ketika tidak dipakai.
  • Hadapkan ujung solder ke atas <waktu pemanasan.
  • Jangan dipakai selain untuk menyoder.
  • Jangan sampai alat basah atau tangan basah.
  • Jangan memodifikasi alat solder. Pakai pengganti DEKKOyang asli.
  • Jangan menggoncang alat solder, bisa menyebabkan elemen pemanas rusak.
  • Proses penyoderan mengeluarkan asap, pastikan ventjlasi ruangan memadai.
  • Jauhkan alat DEKKO dari anak-anak.

PERINGATAN

  • Untuk mencegah luka bakar, jangan menyentuh alat solder yang sendang panas. Dan jangan membiarkan alat solder tanpa terjaga.
  • Jangan memakai alat solder di lingkurigan yang mudah terbakar untuk menghindari kebakaran
