DAC8820ICDBR

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

DAC8820ICDBR 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 REF input Reference input voltage (-15 V to +15 V) for the 4-quadrant resistor network that determines DAC full-scale current.
2 RCOM passive Center tap connection between the two 4-quadrant resistors (R1 and R2) in the multiplying DAC.
3 R1 passive 4-quadrant resistor (R1) element for bipolar multiplying mode operation.
4 ROFS passive Bipolar offset resistor connection for the I/V converter amplifier.
5 RFB passive Internal matching feedback resistor for temperature tracking and I/V converter amplification.
6 IOUT output DAC current output terminal held at virtual ground potential by external I/V converter op-amp.
7 AGND power_in Analog ground reference for the R-2R DAC ladder network.
8 LDAC input Digital control input (active high) to load DAC register from input register and update output.
9 WR input Digital write control input (active low) to load 16-bit data from input pins D0-D15 into input register.
10 D15 input Digital input data bit 15 (MSB) for the 16-bit parallel data bus.
11 D14 input Digital input data bit 14 for the 16-bit parallel data bus.
12 D13 input Digital input data bit 13 for the 16-bit parallel data bus.
13 D12 input Digital input data bit 12 for the 16-bit parallel data bus.
14 D11 input Digital input data bit 11 for the 16-bit parallel data bus.
15 D10 input Digital input data bit 10 for the 16-bit parallel data bus.
16 D9 input Digital input data bit 9 for the 16-bit parallel data bus.
17 D8 input Digital input data bit 8 for the 16-bit parallel data bus.
18 D7 input Digital input data bit 7 for the 16-bit parallel data bus.
19 D6 input Digital input data bit 6 for the 16-bit parallel data bus.
20 D5 input Digital input data bit 5 for the 16-bit parallel data bus.
21 D4 input Digital input data bit 4 for the 16-bit parallel data bus.
22 DGND power_in Digital ground reference for the control logic circuits.
23 VDD power_in Positive power supply voltage from 2.7 V to 5.5 V for digital and analog circuits.
24 D3 input Digital input data bit 3 for the 16-bit parallel data bus.
25 D2 input Digital input data bit 2 for the 16-bit parallel data bus.
26 D1 input Digital input data bit 1 for the 16-bit parallel data bus.
27 D0 input Digital input data bit 0 (LSB) for the 16-bit parallel data bus.
28 RST input Digital reset input (active low) that clears DAC register to zero and sets output to 0 V.
