DAC8551AQDGKRQ1

Texas Instruments · Digital To Analog Converters (DAC) · VSSOP-8-0.65mm

DAC8551AQDGKRQ1 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, specified from 3.2 V to 5.5 V (supply voltage VDD to GND).
2 VREF power_in Reference voltage input, with the reference input voltage range stated as 0 to VDD V.
3 VFB input Feedback connection for the output amplifier; for voltage output operation it must be tied to VOUT externally.
4 VOUT output Analog output voltage from the DAC, with the output amplifier operating rail-to-rail.
5 SYNC input Level-triggered active-low frame synchronization input that enables the input shift register; the DAC updates after the 24th clock unless SYNC goes high first, and it is a Schmitt-trigger logic input.
6 SCLK input Serial clock input for data transfer at rates up to 30 MHz, and it is a Schmitt-trigger logic input.
7 DIN input Serial data input, clocked into the 24-bit input shift register on each falling edge of SCLK, and it is a Schmitt-trigger logic input.
8 GND power_in Ground reference point for all circuitry on the device.
