DAC8554IPW from Texas Instruments, in a TSSOP-16. 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 | VOUTA | output | Analog output voltage from DAC A, swinging rail-to-rail over the 2.7V to 5.5V supply range. |
| 2 | VOUTB | output | Analog output voltage from DAC B, swinging rail-to-rail over the 2.7V to 5.5V supply range. |
| 3 | VrefH | input | Positive reference voltage input, which sets the upper output range (0 to VREFH) and must stay at or below AVDD. |
| 4 | AVDD | power_in | Power supply input, 2.7V to 5.5V. |
| 5 | VrefL | input | Negative reference voltage input, which must stay below VREFH and is limited to AVDD/2 in the reference input specification. |
| 6 | GND | power_in | Ground reference point for all circuitry on the part. |
| 7 | VOUTC | output | Analog output voltage from DAC C, swinging rail-to-rail over the 2.7V to 5.5V supply range. |
| 8 | VOUTD | output | Analog output voltage from DAC D, swinging rail-to-rail over the 2.7V to 5.5V supply range. |
| 9 | SYNC | input | Active-low level-triggered frame sync for the input data; the DAC updates after the 24th clock, and it is a Schmitt-trigger input. |
| 10 | SCLK | input | Serial clock input with data transfer rates up to 50MHz, and it is a Schmitt-trigger input. |
| 11 | 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 input. |
| 12 | IOVDD | power_in | Digital input-output power supply, 1.8V to 5.5V per the logic input specifications. |
| 13 | A0 | input | Address 0 input that sets the device address, see Table 2 of the datasheet. |
| 14 | A1 | input | Address 1 input that sets the device address, see Table 2 of the datasheet. |
| 15 | ENABLE | input | Active-low enable that connects the SPI interface to the serial port when LOW. |
| 16 | LDAC | input | Load DACs input, rising-edge triggered, which loads all DAC registers. |
