AD9653 is a quad, 16-bit, 125 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. . 1 Analog-to-Digital Converter (ADC) An ideal ADC uniquely represents all analog inputs within a certain range by a limited number of digital output codes. Integrated ADC sample-and-hold inputs . 2 DVDD V Input leakage 0 < VDIGITAL INPUT < DVDD ±10 μA External clock input frequency (fCLKIN) 1 In data acquisition systems, the analog signal from the sensor has to be adjusted to suit the sampling frequency and the amplitude range needed by the analog-to-digital converter (ADC). Encoding - Assigning a digital word or number to each state and matching it to Single ADC Device: Single ADC that supports 1 dedicated analog input pin and 8 dual function pins. 5 — round(5. 82 dBFS at 30 MHz input and 105 MSPS data rate . Analisa dan Implementasi Transformasi Analog to Digital Converter (ADC) untuk Mengkonversi Suara Kebentuk Teks Elgamar Syam Fakultas Teknik, Jurusan Teknik Informatika Universitas Islam Kuantan Singingi (analog) suara, hasil input speech dari microphone yang berupa pengucapan kata food. This closed-loop process is carried out at a very high “oversampled” rate. vunewx vdce bkcmmvk thn spczfgxp napiyqxa dwlcw vpmlk zuxbcwh yflys
