AD9833BRMZ-REEL

Analog Devices · Direct Digital Synthesis (DDS) · MSOP-10

AD9833BRMZ-REEL from Analog Devices, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 COMP passive DAC bias pin. Used for decoupling the DAC bias voltage (typically bypassed to VDD with a 10 nF capacitor).
2 VDD power_in Positive power supply for the analog and digital interface sections. VDD range is 2.3 V to 5.5 V. Also feeds the on-board 2.5 V regulator; decouple with 0.1 uF and 10 uF between VDD and AGND.
3 CAP/2.5V passive Regulated 2.5 V rail for internal digital circuitry, generated from VDD by the on-board regulator when VDD > 2.7 V. Requires a 100 nF decoupling capacitor from CAP/2.5V to DGND. If VDD <= 2.7 V, tie CAP/2.5V directly to VDD.
4 DGND power_in Digital ground return.
5 MCLK input Digital master clock input. DDS output frequencies are expressed as a binary fraction of fMCLK; this clock determines output frequency accuracy and phase noise. Max 25 MHz; period tMIN = 40 ns.
6 SDATA input Serial data input. The 16-bit serial data-word is applied to this input (3-wire SPI, MSB first).
7 SCLK input Serial clock input. Data on SDATA is clocked into the AD9833 on each falling edge of SCLK. SCLK period min 25 ns (up to 40 MHz).
8 FSYNC input Active-low frame synchronization / chip-select input. When FSYNC is taken low, the internal logic is informed that a new 16-bit word is being loaded into the device.
9 AGND power_in Analog ground return.
10 VOUT output Analog and digital output of the AD9833. Delivers sine, triangle, or square wave (MSB) with VOUT max ~0.65 V typical. An external load resistor is not required; the device has an on-board 200 ohm resistor to AGND.
