Wide supply voltage range of 2.5V to 5.5V (vs AD9834BRUZ)

Design Notes

Decouple the VDD pin with a 10uF and 0.1uF capacitor placed as close to the pin as possible. The CAP/2.5V pin requires a 100nF capacitor to ground for internal digital circuitry. Ensure a clean, low-impedance ground plane to minimize noise coupling into the analog output.

Keep the SPI lines (SDATA, SCLK, FSYNC) short and away from the analog output (VOUT) to prevent digital noise coupling. Use series resistors (e.g., 33 ohm) on the SPI lines to reduce ringing. The MCLK input should be driven with a clean clock source, and the trace should be impedance-controlled if possible.

Ensure the FSYNC line is held high during power-up and only pulled low to initiate a write. The AD9833 requires a 3-wire SPI write sequence; incorrect timing can cause data corruption. Also, the output is a current output from the DAC; use an external op-amp to convert to voltage and buffer the signal.
