DAC6551AQDGKRQ1 from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input, rated 3.2 V to 5.5 V |
| 2 | VREF | power_in | Reference voltage input with input voltage range 0 V to VDD |
| 3 | VFB | input | Feedback connection for the output amplifier; tie to VOUT externally for voltage output operation |
| 4 | VOUT | output | Analog output voltage from DAC with rail-to-rail operation capability |
| 5 | SYNC | input | Level-triggered control input (active-low) for frame synchronization of input data; Schmitt-trigger logic input |
| 6 | SCLK | input | Serial clock input supporting data transfer rates up to 30 MHz; Schmitt-trigger logic input |
| 7 | DIN | input | Serial data input clocked into 24-bit input shift register on falling edges of serial clock; Schmitt-trigger logic input |
| 8 | GND | power_in | Ground reference point for all circuitry on the device |
