I-AD9914BCPZ IC DDS 12BIT 88LFCSP

Incazelo

I-AD9914 iyinhlangano eqondile yedijithali (i-DDS) equkethe i-DAC engu-12-bit.I-AD9914 isebenzisa ubuchwepheshe obuthuthukisiwe be-DDS, obuhambisana nesivinini esiphezulu sangaphakathi, ukusebenza okuphezulu kwe-DAC ukuze kwakheke i-synthesizer ehlelekayo ngokwedijithali, ephelele yamafrikhwensi aphezulu ekwazi ukukhiqiza i-frequency-agile analog output sinusoidal waveform efinyelela ku-1.4 GHz.I-AD9914 inika amandla ukugxuma kwefrikhwensi esheshayo nokulungiswa kahle kokushunwa (i-64-bit ekwazi ukusebenzisa imodi yemodulus ehlelekayo).I-AD9914 iphinde inikeze isigaba esisheshayo namandla okugxuma ama-amplitude.Amagama okushuna imvamisa nokulawula alayishwa ku-AD9914 ngembobo ye-serial noma ehambisanayo yokufaka/yokukhiphayo.I-AD9914 futhi isekela imodi yokushanela echazwe ngumsebenzisi echazwe ngomugqa ukuze kukhiqizwe amagagasi ashanelwe alandelanayo wefrikhwensi, isigaba, noma i-amplitude.Isivinini esikhulu, imbobo yokufaka yedatha ehambisanayo engu-32-bit ifakiwe, evumela amanani edatha aphezulu ezikimu zokushintshashintsha kwendawo kanye nokuhlelwa kabusha okusheshayo kwesigaba, imvamisa, namagama okushuna ama-amplitude.I-AD9914 icaciswe ukuthi isebenze phezu kwebanga lokushisa elinwetshiwe lemboni (bona isigaba se-Absolute Maximum Ratings).
