Description
Digital Inputs.
Digital I/O Supply Voltage (1.8 V to 3.3 V Nominal).
Digital Common.
Digital Core Supply Voltage (1.8 V to 3.3 V).
No Connect. These pins are not connected to the chip.
Sampling Clock Supply Voltage (1.8 V to 3.3 V). CVDD must be ≥ DVDD.
LVCMOS Sampling Clock Input.
Sampling Clock Supply Voltage Common.
Q DAC Output Common-Mode Level.
Load Resistor (62.5 Ω) to the CMLQ Pin.
Complementary Q DAC Current Output. Full-scale current is sourced when all data bits are 0s.
Q DAC Current Output. Full-scale current is sourced when all data bits are 1s.
Load Resistor (62.5 Ω) to the CMLQ Pin.
Analog Common.
Analog Supply Voltage (1.8 V to 3.3 V).
Load Resistor (62.5 Ω) to the CMLI Pin.
Complementary I DAC Current Output. Full-scale current is sourced when all data bits are 0s.
Load Resistor (62.5 Ω) to the CMLI Pin.
I DAC Output Common-Mode Level.
Auxiliary Q DAC Output When Internal On-Chip, R
Full-Scale Current Output Adjust for I DAC. Connect to AVSS through a resistor.
Auxiliary I DAC Output When Internal On-Chip, R
Reference Input/Output. Serves as a reference input when the internal reference is disabled. Provides a 1.0 V
reference output when in internal reference mode (a 0.1 μF capacitor to AVSS is required).
Reset. In SPI mode, pulse RESET high to reset SPI registers to default values.
Pin Mode. A constant Logic 1 puts the device into pin mode.
Digital Inputs.
Digital Input (LSB).
Data Input/Output Clock. Clock used to qualify input data.
I DAC Current Output. Full-scale current is sourced when all data bits are 1s.
Full-Scale Current Output Adjust for Q DAC. Connect to AVSS through a resistor.
NC = NO CONNECT
NOTES
1. THE HEAT SINK PAD IS CONNECTED TO AVSS AND
MUST BE SOLDERED TO THE GROUND PLANE.
EXPOSED METAL AT PACKAGE CORNERS IS
