Pin Functions

PIN TYPE EQUIVALENT CIRCUIT DESCRIPTION
NAME WSON SOT VSSOP
ADR0 1 6 1 Digital Input,
three levels 		DAC101C081 DAC101C081Q DAC101C085 30052262.gif Tri-state Address Selection Input. Sets the two Least Significant Bits (A1 and A0) of the 7-bit slave address. (see Table 1)
ADR1 — — 2 Digital Input,
three levels		 Tri-State Address Selection Input. Sets Bits A6 and A3 of the 7-bit slave address. (see Table 1)
GND 4 3 5 Ground Ground for all on-chip circuitry
PAD PAD — — Ground Exposed die attach pad can be connected to ground or left floating. Soldering the pad to the PCB offers optimal thermal performance and enhances package self-alignment during reflow.
SCL 2 5 3 Digital Input DAC101C081 DAC101C081Q DAC101C085 30052261.gif Serial Clock Input. SCL is used together with SDA to control the transfer of data in and out of the device.
SDA 3 4 4 Digital
Input/Output		 Serial Data bi-directional connection. Data is clocked into or out of the internal 16-bit register relative to the clock edges of SCL. This is an open drain data line that must be pulled to the supply (VA) by an external pullup resistor.
VA 5 2 6 Supply Power supply input. For the SOT and WSON versions, this supply is used as the reference. Must be decoupled to GND.
VOUT 6 1 8 Analog Output Analog Output Voltage
VREF — — 7 Supply Unbufferred reference voltage. For the VSSOP-8, this supply is used as the reference. VREF must be free of noise and decoupled to GND.
