BUF12840AIRGER

Texas Instruments · Video Amplifiers · VQFN-24(4x4)

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).
