Mnemonic
Description
28 to 32,
1, 2, 4
DB8 to DB1
Data Bit 8 to Data Bit 1.
3
DVDD
Digital Supply Voltage (1.7 V to 3.6 V).
5
DB0 (LSB)
Least Significant Data Bit (LSB).
6 to 9
NC
No Connect.
10, 26
DCOM
Digital Common.
11
CLKVDD
Clock Supply Voltage (1.7 V to 3.6 V).
12
CLK+
Positive Differential Clock Input.
13
CLK
Negative Differential Clock Input.
14
CLKCOM
Clock Common.
15
CMODE/SCLK
In pin mode, this pin selects the clock input type. Connect to CLKCOM for single-ended clock receiver (drive
CLK+ and float CLK–). Connect to CLKVDD for differential receiver. In SPI mode, this pin is the serial data clock input.
16
MODE/SDIO
In pin mode, this pin selects the input data format. Connect to DCOM for straight binary, and DVDD for twos
complement. In SPI mode, this pin acts as SPI data input/output.
17
PIN/SPI/RESET
Selects SPI Mode or Pin Mode Operation. Active high for pin mode operation and active low for SPI mode
operation. Pulse high to reset SPI registers to default values.
18
AVDD
Analog Supply Voltage (1.7 V to 3.6 V).
19
OTCM
Adjustable Output Common Mode. Refer to the Theory of Operation section for details.
20
IOUTB
Complementary DAC Current Output. Full-scale current is sourced when all data bits are 0s.
21
IOUTA
DAC Current Output. Full-scale current is sourced when all data bits are 1s.
22
ACOM
Analog Common.
23
REFIO
Reference Input/Output. Serves as reference input when internal reference disabled. Serves as 1.0 V reference
output when internal reference is activated. Requires a 0.1 μF capacitor to ACOM when internal reference is activated.
24
FS ADJ
Full-Scale Current Output Adjust.
25
SLEEP/CSB
In pin mode, active high powers down chip. In SPI mode, this pin is the serial port chip select (active low).
27
DB9 (MSB)
Most Significant Data Bit (MSB).
EPAD
It is recommended that the exposed pad be thermally connected to a copper ground plane for enhanced
electrical and thermal performance.
