Texas Instruments · Digital To Analog Converters (DAC) · SSOP-28

DAC8814ICDBT from Texas Instruments, in a SSOP-28. 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 AGNDA power_in DAC A analog ground; the datasheet recommends connecting all AGNDX pins directly to an analog ground plane at the unit.
2 IOUTA output DAC A current output, which feeds the external I-to-V amplifier virtual ground.
3 VREFA input DAC A reference voltage input that sets the full-scale output; it can be tied to VDD.
4 RFBA input DAC A feedback resistor terminal that establishes the output voltage when connected to the external amplifier output.
5 MSB input Sets the reset code during a RS pulse or at power-on: tied to ground gives zero code and tied to VDD gives half-scale (8000h).
6 RS input Active-low asynchronous reset that forces the input and DAC registers to zero code or half-scale (8000h), depending on MSB.
7 VDD power_in Positive power supply input; specified range of operation is +2.7 V to +5.5 V.
8 CS input Active-low chip select that disables shift register loading when high and transfers shift register data to the input register on its rising edge.
9 CLK input Clock input; the positive edge clocks data into the shift register.
10 SDI input Serial data input that loads directly into the shift register.
11 RFBB input DAC B feedback resistor terminal that establishes the output voltage when connected to the external amplifier output.
12 VREFB input DAC B reference voltage input that sets the full-scale output; it can be tied to VDD.
13 IOUTB output DAC B current output, which feeds the external I-to-V amplifier virtual ground.
14 AGNDB power_in DAC B analog ground; the datasheet recommends connecting all AGNDX pins directly to an analog ground plane at the unit.
15 AGNDC power_in DAC C analog ground; the datasheet recommends connecting all AGNDX pins directly to an analog ground plane at the unit.
16 IOUTC output DAC C current output, which feeds the external I-to-V amplifier virtual ground.
17 VREFC input DAC C reference voltage input that sets the full-scale output; it can be tied to VDD.
18 RFBC input DAC C feedback resistor terminal that establishes the output voltage when connected to the external amplifier output.
19 NC unconnected Not connected internally; leave floating.
20 SDO output Serial data output for daisy-chaining; data appears at SDO 19 clock pulses after it is applied at SDI.
21 LDAC input Level-sensitive active-low asynchronous load DAC strobe that transfers all input register data to the DAC registers.
22 AGNDF power_in High-current analog force ground for the analog section.
23 VSS power_in Labeled VSS but stated to have no internal connection.
24 DGND power_in Digital ground for the logic interface.
25 RFBD input DAC D feedback resistor terminal that establishes the output voltage when connected to the external amplifier output.
26 VREFD input DAC D reference voltage input that sets the full-scale output; it can be tied to VDD.
27 IOUTD output DAC D current output, which feeds the external I-to-V amplifier virtual ground.
28 AGNDD power_in DAC D analog ground; the datasheet recommends connecting all AGNDX pins directly to an analog ground plane at the unit.
