TLC7628CDWR from Texas Instruments, in a SOIC-20-300mil. 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 | AGND | power_in | Analog ground terminal shared by both DACs (DACA and DACB), used as the ground reference for the analog outputs. |
| 2 | OUTA | output | DACA current output; output voltage to AGND is absolute-maximum rated at ±25 V. |
| 3 | RFBA | passive | DACA internal feedback resistor terminal for the external op-amp; feedback voltage to AGND is absolute-maximum rated at ±25 V. |
| 4 | REFA | input | DACA reference voltage input, specified for ±10 V with an input resistance of 5 to 20 kΩ to AGND. |
| 5 | DGND | power_in | Digital ground reference for the digital inputs; input voltage range is −0.3 V to VDD + 0.3 V referenced to DGND. |
| 6 | DACA/DACB | input | Control input that selects which DAC data latch (A or B) is loaded from the common 8-bit input port. |
| 7 | DB7 | input | Most significant bit (MSB) of the 8-bit data input port; TTL-compatible with VIH minimum 2.4 V and VIL maximum 0.8 V. |
| 8 | DB6 | input | Data bit 6 of the 8-bit common input port; TTL-compatible with VIH minimum 2.4 V and VIL maximum 0.8 V. |
| 9 | DB5 | input | Data bit 5 of the 8-bit common input port; TTL-compatible with VIH minimum 2.4 V and VIL maximum 0.8 V. |
| 10 | DB4 | input | Data bit 4 of the 8-bit common input port; TTL-compatible with VIH minimum 2.4 V and VIL maximum 0.8 V. |
| 11 | DB3 | input | Data bit 3 of the 8-bit common input port; setup time 25 ns and hold time 10 ns to WR per the recommended operating conditions. |
| 12 | DB2 | input | Data bit 2 of the 8-bit common input port; setup time 25 ns and hold time 10 ns to WR per the recommended operating conditions. |
| 13 | DB1 | input | Data bit 1 of the 8-bit common input port; setup time 25 ns and hold time 10 ns to WR per the recommended operating conditions. |
| 14 | DB0 | input | Least significant bit (LSB) of the 8-bit data input port; setup time 25 ns and hold time 10 ns to WR per the recommended operating conditions. |
| 15 | CS | input | Chip select; must be low for a write, with setup time 50 ns and hold time 0 ns, and when high the data inputs are disabled regardless of WR. |
| 16 | WR | input | Write strobe; pulse duration low minimum 50 ns, with CS and WR both low making the input latches transparent. |
| 17 | VDD | power_in | Positive supply, specified 10.8 V to 15.75 V and absolute-maximum rated at 17 V to AGND or DGND. |
| 18 | REFB | input | DACB reference voltage input, specified for ±10 V with an input resistance of 5 to 20 kΩ to AGND. |
| 19 | RFBB | passive | DACB internal feedback resistor terminal for the external op-amp; feedback voltage to AGND is absolute-maximum rated at ±25 V. |
| 20 | OUTB | output | DACB current output; output voltage to AGND is absolute-maximum rated at ±25 V. |
