11 mW Power, 2.3 V to 5.5 V,
Complete DDS
AD9838
FEATURES Capability for phase modulation and frequency modulation is
provided. The frequency registers are 28 bits wide: with a 16 MHz
clock rate, resolution of 0.06 Hz can be achieved; with a 5 MHz
clock rate, the AD9838 can be tuned to 0.02 Hz resolution.
Frequency and phase modulation are configured by loading
registers through the serial interface and by toggling the registers
using software or the FSELECT and PSELECT pins, respectively. 2.3 V to 5.5 V power supply
MCLK speed: 16 MHz (B grade), 5 MHz (A grade)
Output frequency up to 8 MHz
Sinusoidal and triangular outputs
On-board comparator
3-wire SPI interface
Extended temperature range: −40°C to +125°C
Power-down option
11 mW power consumption at 2.3 V
20-lead LFCSP The AD9838 is written to via 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 from …
