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

DAC8814IBDBT 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.
2 IOUTA output DAC A current output with 2 mA maximum full-scale output current at 10 V VREF.
3 VREFA input DAC A reference voltage input terminal with ±18 V maximum range establishing full-scale output voltage.
4 RFBA passive DAC A feedback resistor connection for external I-to-V converter.
5 MSB input MSB bit set during reset pulse or power-on; sets registers to 8000h when high or 0000h when low.
6 RS input Reset pin active low; forces all input and DAC registers to zero-code (MSB = 0) or half-scale code 8000h (MSB = 1).
7 VDD power_in Positive power-supply input with specified operating range +2.7 V to +5.5 V.
8 CS input Chip select active low input; disables shift register loading when high and transfers shift register data to input register when going high.
9 CLK input Clock input positive edge triggered; clocks serial data into the 18-bit shift register at rates up to 50 MHz.
10 SDI input Serial data input loading MSB-first data directly into the shift register.
11 RFBB passive DAC B feedback resistor connection for external I-to-V converter.
12 VREFB input DAC B reference voltage input terminal with ±18 V maximum range establishing full-scale output voltage.
13 IOUTB output DAC B current output with 2 mA maximum full-scale output current at 10 V VREF.
14 AGNDB power_in DAC B analog ground.
15 AGNDC power_in DAC C analog ground.
16 IOUTC output DAC C current output with 2 mA maximum full-scale output current at 10 V VREF.
17 VREFC input DAC C reference voltage input terminal with ±18 V maximum range establishing full-scale output voltage.
18 RFBC passive DAC C feedback resistor connection for external I-to-V converter.
19 NC unconnected No internal connection; leave floating.
20 SDO output Serial data output with data available 19 clock pulses after serial data input at SDI pin for daisy-chaining multiple devices.
21 LDAC input Load DAC register strobe level-sensitive active low input; transfers all input register data to DAC registers asynchronously.
22 AGNDF power_in High current analog force ground.
23 VSS power_in No internal connection; leave floating.
24 DGND power_in Digital ground.
25 RFBD passive DAC D feedback resistor connection for external I-to-V converter.
26 VREFD input DAC D reference voltage input terminal with ±18 V maximum range establishing full-scale output voltage.
27 IOUTD output DAC D current output with 2 mA maximum full-scale output current at 10 V VREF.
28 AGNDD power_in DAC D analog ground.
