BUF12840AIRGER from Texas Instruments, in a VQFN-24(4x4). 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 | OUT5 | output | DAC gamma output channel 5, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 2 | OUT4 | output | DAC gamma output channel 4, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 3 | OUT3 | output | DAC gamma output channel 3, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 4 | OUT2 | output | DAC gamma output channel 2, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 5 | OUT1 | output | DAC gamma output channel 1, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 6 | OUT0 | output | DAC gamma output channel 0, the reset-value output (code 0 gives 0 V after reset). |
| 7 | VS | power_in | Analog supply input; operating range is 9 V to 20 V and the absolute maximum is 22 V. |
| 8 | GNDA | power_in | Analog ground; must be connected to GNDD (digital ground). |
| 9 | VSD | power_in | Digital supply input; operating range is 2.0 V to 5.5 V and the absolute maximum is 6 V. |
| 10 | EA1 | input | EEPROM select bit 1; must be tied to logic 0 if autoread is not used. |
| 11 | EA0 | input | EEPROM select bit 0; must be tied to logic 0 if autoread is not used. |
| 12 | EN | input | EEPROM enable; must be 0 if autoread is not used. |
| 13 | LD | input | Latch pin; LD = 0 is the condition for the stated bank switching delay of 7 µs typical and 10 µs maximum. |
| 14 | SCL | input | Two-wire interface serial clock, supporting 400 kHz standard/fast mode and 3.4 MHz high-speed mode. |
| 15 | SDA | bidirectional | Two-wire interface serial data, supporting 400 kHz standard/fast mode and 3.4 MHz high-speed mode. |
| 16 | A0 | input | Slave address select input for the two-wire interface. |
| 17 | BKSEL | input | Bank select input that chooses between the two independent memory banks. |
| 18 | GNDD | power_in | Digital ground; must be connected to GNDA (analog ground). |
| 19 | OUT11 | output | DAC gamma output channel 11, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 20 | OUT10 | output | DAC gamma output channel 10, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 21 | OUT9 | output | DAC gamma output channel 9, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 22 | OUT8 | output | DAC gamma output channel 8, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 23 | OUT7 | output | DAC gamma output channel 7, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 24 | OUT6 | output | DAC gamma output channel 6, rail-to-rail, with 30 mA maximum continuous output current for channels 1 to 12. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
