TABLE 3-2: MCP47CXBX2 (DUAL DAC) PIN FUNCTION TABLE Pin Symbol I/O Buffer Type Description MSOP 10L DFN 10L QFN 16L 11 16 VDD — P Supply Voltage Pin 22 1 A0 I ST I2C Slave Address Bit 0 Pin 33 — VREF A Analog Voltage Reference Input/Output Pin —— 2 VREF0 A Analog Voltage Reference Input/Output Pin for DAC0 —— 4 VREF1 A Analog Voltage Reference Input/Output Pin for DAC1 44 3 VOUT0 A Analog Buffered Analog Voltage Output 0 Pin 55 5 VOUT1 A Analog Buffered Analog Voltage Output 1 Pin — — 6,7,14, 15 NC — — Not Internally Connected 66 — LAT/HVC I ST DAC Wiper Register Latch/High-Voltage Command Pin. The Latch pin allows the value in the Volatile DAC registers (Wiper and Configuration bits) to be transferred to the DAC output (VOUT). High-voltage commands allow the user MTP Configuration bits to be written. —— 9 LAT0/HVC I ST DAC0 Wiper Register Latch/High-Voltage Command Pin. The Latch pin allows the value in the Volatile DAC0 registers (Wiper and Configuration bits) to be transferred to the DAC0 output (VOUT0). High-voltage commands allow the user MTP Configuration bits to be written. —— 8 LAT1 I ST DAC1 Wiper Register Latch Pin. The Latch pin allows the value in the Volatile DAC1 registers (Wiper and Configuration bits) to be transferred to the DAC1 output (VOUT1). 77 10 VSS — P Ground Reference Pin for all circuitries on the device 88 11 A1 I ST I2C Slave Address Bit 1 Pin 9 9 12 SCL I ST I2C Serial Clock Pin 10 10 13 SDA I/O ST I2C Serial Data Pin Note 1: A = Analog, I = Input, ST = Schmitt Trigger, O = Output, I/O = Input/Output, P = Power |
