AD9833BRMZ 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 decoupled with a 10 nF capacitor to VDD.
2	VDD	power_in	Positive Power Supply for the analog and digital interface sections (2.3 V to 5.5 V). Also supplies the on-board 2.5 V regulator. Should be decoupled with 0.1 µF and 10 µF capacitors to AGND.
3	CAP/2.5V	passive	Regulator output/bypass. The digital circuitry operates from 2.5 V generated by an on-board regulator from VDD (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 Clock Input. DDS output frequencies are expressed as a binary fraction of MCLK; determines output frequency accuracy and phase noise. Max 25 MHz (t1 ≥ 40 ns period).
6	SDATA	input	Serial Data Input. 16-bit serial data-word applied to this input; clocked in on falling edge of SCLK.
7	SCLK	input	Serial Clock Input. Data is clocked into the AD9833 on each falling edge of SCLK. Rates up to 40 MHz.
8	FSYNC	input	Active Low Control Input (frame sync). 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	Voltage Output. Analog and digital output of the AD9833 (sine, triangle, or square wave). An external load resistor is not required because the device has an on-board 200 Ω resistor. VOUT max ~0.65 V, min ~38 mV.
