20 mW Power, 2.3 V to 5.5 V,
75 MHz Complete DDS
AD9834 Data Sheet
FEATURES Capability for phase modulation and frequency modulation is
provided. The frequency registers are 28 bits; with a 75 MHz clock
rate, resolution of 0.28 Hz can be achieved. Similarly, with a 1 MHz
clock rate, the AD9834 can be tuned to 0.004 Hz resolution.
Frequency and phase modulation are affected by loading registers
through the serial interface and toggling the registers using
software or the FSELECT pin and PSELECT pin, respectively. Narrow-band SFDR >72 dB
2.3 V to 5.5 V power supply
Output frequency up to 37.5 MHz
Sine output/triangular output
On-board comparator
3-wire SPI® interface
Extended temperature range: −40°C to +105°C
Power-down option
20 mW power consumption at 3 V
20-lead TSSOP The AD9834 is written to using a 3-wire serial interface. This
serial interface operates at clock rates up to 40 MHz and is
compatible with DSP and microcontroller standards.
The device operates with a power supply from 2.3 V to 5.5 V.
The analog and digital sections are independent and can be run …
