DAC7625UB from Texas Instruments, in a SOIC-28-300mil. 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 | VREFH | input | Reference input voltage high that sets the maximum output voltage for all DACs, and must be at least 1.25V greater than VREFL. |
| 2 | VOUTB | output | DAC B voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation. |
| 3 | VOUTA | output | DAC A voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation. |
| 4 | VSS | power_in | Negative analog supply voltage of 0V or -5V; if not 0V it must be within -4.75V to -5.25V. |
| 5 | GND | power_in | Ground reference pin. |
| 6 | RESET | input | Asynchronous reset input that sets the DAC and input registers to mid-scale (800H) on the DAC7624 or zero-scale (000H) on the DAC7625 when LOW. |
| 7 | LDAC | input | Load DAC input; all DAC registers are transparent when LOW. |
| 8 | DB0 | bidirectional | Data bit 0, the least significant bit of the 12-bit word; bus is also driven for readback. |
| 9 | DB1 | bidirectional | Data bit 1 of the 12-bit parallel word; bus is also driven for readback. |
| 10 | DB2 | bidirectional | Data bit 2 of the 12-bit parallel word; bus is also driven for readback. |
| 11 | DB3 | bidirectional | Data bit 3 of the 12-bit parallel word; bus is also driven for readback. |
| 12 | DB4 | bidirectional | Data bit 4 of the 12-bit parallel word; bus is also driven for readback. |
| 13 | DB5 | bidirectional | Data bit 5 of the 12-bit parallel word; bus is also driven for readback. |
| 14 | DB6 | bidirectional | Data bit 6 of the 12-bit parallel word; bus is also driven for readback. |
| 15 | DB7 | bidirectional | Data bit 7 of the 12-bit parallel word; bus is also driven for readback. |
| 16 | DB8 | bidirectional | Data bit 8 of the 12-bit parallel word; bus is also driven for readback. |
| 17 | DB9 | bidirectional | Data bit 9 of the 12-bit parallel word; bus is also driven for readback. |
| 18 | DB10 | bidirectional | Data bit 10 of the 12-bit parallel word; bus is also driven for readback. |
| 19 | DB11 | bidirectional | Data bit 11, the most significant bit of the 12-bit word; bus is also driven for readback. |
| 20 | R/W | input | Read/write control input: read when HIGH, write when LOW. |
| 21 | A1 | input | Register/DAC select input: C or D when HIGH, A or B when LOW. |
| 22 | A0 | input | Register/DAC select input: B or D when HIGH, A or C when LOW. |
| 23 | CS | input | Chip select input. |
| 24 | NIC | unconnected | Not internally connected; the pin has no internal connection to the device. |
| 25 | VDD | power_in | Positive analog supply voltage, +5V nominal, specified from 4.75V to 5.25V. |
| 26 | VOUTD | output | DAC D voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation. |
| 27 | VOUTC | output | DAC C voltage output, specified for output current of ±1.25mA and load capacitance up to 100pF without oscillation. |
| 28 | VREFL | input | Reference input voltage low that sets the minimum output voltage for all DACs. |
