Pin No.
Mnemonic
Description
28
D0N
Data Bit 0 (LSB), Negative.
29
DVDD18
1.8 V Digital Supply. Supplies power to digital core and digital data ports.
30
TXENABLE
Active High Transmit Path Enable (CMOS). A low level on this pin clamps the DAC outputs to midscale.
31
SDIO
Serial Port Data Input/Output (CMOS).
32
SCLK
Serial Port Clock Input (CMOS).
33
CS
Serial Port Chip Select, Active Low (CMOS).
34
IRQ
Interrupt Request. Open-drain, active low output. Pull this pin high external to the device.
35
DVDD18
1.8 V Digital Supply. Supplies power to digital core and digital data ports.
36
RESET
Reset, Active Low (CMOS).
37
AVDD33
3.3 V Analog Supply.
38
IOUT2P
Q DAC Positive Current Output.
39
IOUT2N
Q DAC Negative Current Output.
40
AVDD33
3.3 V Analog Supply.
41
AVSS
Analog Supply Common.
42
REFIO
1.2 V Band Gap Voltage Reference Output. Should be decoupled to AVSS with a 0.1 F capacitor.
43
FSADJ
Full-Scale Current Output Adjust. Place a 10 kΩ resistor from this pin to AVSS.
44
AVSS
Analog Supply Common.
45
AVDD33
3.3 V Analog Supply.
46
IOUT1N
I DAC Negative Current Output.
47
IOUT1P
I DAC Positive Current Output.
48
AVDD33
3.3 V Analog Supply.
EPAD
The exposed pad (EPAD) must be soldered to the ground plane (AVSS). The EPAD provides an electrical,
thermal, and mechanical connection to the board.
