# TLV5628CDWR

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

TLV5628CDWR 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 | DACB | output | DACB analog voltage output, which swings between GND and either 1 or 2 times its reference voltage as selected by the RNG bit. |
| 2 | DACA | output | DACA analog voltage output, which swings between GND and either 1 or 2 times its reference voltage as selected by the RNG bit. |
| 3 | GND | power_in | Ground return and reference terminal; the DAC resistor strings are tied to this pin and the device is monotonic referenced to it. |
| 4 | DATA | input | Serial-interface digital data input; the 12-bit command word is entered MSB first, clocked in on each falling edge of CLK while LOAD is high. |
| 5 | CLK | input | Serial-interface clock; data enters on the negative (falling) edge, with a maximum CLK frequency of 1 MHz. |
| 6 | VDD | power_in | Positive supply voltage; recommended range is 2.7 V to 5.25 V, and the electrical characteristics are specified for 3 V to 3.6 V. |
| 7 | DACE | output | DACE analog voltage output, which swings between GND and either 1 or 2 times the REF2 reference voltage as selected by the RNG bit. |
| 8 | DACF | output | DACF analog voltage output, which swings between GND and either 1 or 2 times the REF2 reference voltage as selected by the RNG bit. |
| 9 | DACG | output | DACG analog voltage output, which swings between GND and either 1 or 2 times the REF2 reference voltage as selected by the RNG bit. |
| 10 | DACH | output | DACH analog voltage output, which swings between GND and either 1 or 2 times the REF2 reference voltage as selected by the RNG bit. |
| 11 | REF2 | input | High-impedance buffered reference voltage input for DACE through DACH; the DACs present a high-impedance load to this source. |
| 12 | LOAD | input | Serial-interface load control; after all data bits are clocked in, LOAD is pulsed low to transfer the word to the selected DAC. |
| 13 | LDAC | input | DAC-update latch control; when LDAC is low the selected DAC output updates with LOAD, and when high the new value is held until LDAC is pulsed low. |
| 14 | REF1 | input | High-impedance buffered reference voltage input for DACA through DACD per the detailed description; the DACs present a high-impedance load to this source. |
| 15 | DACD | output | DACD analog voltage output, which swings between GND and either 1 or 2 times the REF1 reference voltage as selected by the RNG bit. |
| 16 | DACC | output | DACC analog voltage output, which swings between GND and either 1 or 2 times the REF1 reference voltage as selected by the RNG bit. |
