**Texas Instruments** · Digital To Analog Converters (DAC) · SOIC-16-300mil

DAC7616UB from Texas Instruments, in a SOIC-16-300mil. 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 | VDD | power_in | Positive analog supply voltage, +3V nominal, with a specified range of 3.0 V to 3.6 V. |
| 2 | VOUTD | output | DAC D voltage output, which can swing down to ground; output current is specified at -625 µA to +625 µA. |
| 3 | VOUTC | output | DAC C voltage output, which can swing down to ground; output current is specified at -625 µA to +625 µA. |
| 4 | VREFL | input | Reference input voltage low; sets the minimum output voltage for all DACs, with an input range of 0 V. |
| 5 | VREFH | input | Reference input voltage high; sets the maximum output voltage for all DACs, with an input range of 0 V to +1.25 V. |
| 6 | VOUTB | output | DAC B voltage output, which can swing down to ground; output current is specified at -625 µA to +625 µA. |
| 7 | VOUTA | output | DAC A voltage output, which can swing down to ground; output current is specified at -625 µA to +625 µA. |
| 8 | AGND | power_in | Analog ground pin for the device. |
| 9 | GND | power_in | Device ground; the single ground pin, through which all digital and analog return currents must flow. |
| 10 | SDI | input | Serial data input carrying the 16-bit word (2-bit DAC address, two unused bits, then 12-bit code, MSB first), clocked by CLK. |
| 11 | CLK | input | Serial data clock; ORed with CS to advance the internal shift register, and the two inputs are interchangeable. |
| 12 | CS | input | Chip select input that enables serial communication when multiple serial devices share the bus; ORed with CLK to advance the shift register. |
| 13 | NIC | unconnected | Not internally connected. |
| 14 | LDAC | input | The selected DAC register becomes transparent when LDAC is LOW and is latched when LDAC is HIGH. |
| 15 | RESET | input | Asynchronous reset input; when LOW, sets all DAC registers to zero-scale (000H) or mid-scale (800H) as selected by RESETSEL. |
| 16 | RESETSEL | input | When LOW, a LOW on RESET sets all DAC registers to 000H; when HIGH, a LOW on RESET sets them to 800H. |
