AD9831ASTZ
Digital Synthesizer, Waveform Generator, 2.97 to 5.5 V, 25 MHz, -40 to 85 °C, LQFP-48
產品總覽
AD9831 DDS device is a numerically controlled oscillator employing a phase accumulator, a sine look-up table, and a 10bit D/A converter integrated on a single CMOS chip. Modulation capabilities are provided for phase modulation and frequency modulation. Modulation is effected by loading registers through the parallel microprocessor interface. A power-down pin allows external control of a power-down mode. Application includes DDS tuning, digital demodulation.
- 3V/5V power supply, 25MHz speed
- Resolution is 10bit (VDD = +3.3V 6 10%, +5V 6 10%)
- On-chip SINE look-up table, parallel loading
- Nominal update rate (fMAX) is 25MSPS (VDD = +3.3V 6 10%, +5V 6 10%), 125mW (5V) power consumption
- Maximum output compliance is 1.5V (VDD = +3.3V 6 10%, +5V 6 10%)
- Typical integral nonlinearity is ±1LSB (VDD = +3.3V 6 10%, +5V 6 10%)
- Signal to noise ratio is 50dB (min, fMCLK = 25MHz, fOUT = 1MHz)
