50 / 112 page  MCP48FXBX4/8 DS20006362A-page 50 2020 Microchip Technology Inc. TABLE 3-2: MCP48FXBX8 (OCTAL DAC) PIN FUNCTION TABLE Pin Description 20-Lead TSSOP 20-Lead VQFN Symbol I/O Buffer Type 119 LAT1 I ST DAC Register Latch Pin. The Latch 1 pin allows the value in the volatile DAC1/DAC3/DAC5/DAC7 registers (wiper and Configura- tion bits) to be transferred to the DAC1/DAC3/DAC5/DAC7 outputs (VOUT1, VOUT3, VOUT5, VOUT7). 220 VDD — P Supply Voltage Pin 31 CS I ST SPI Chip Select Pin 42 VREF0 A Analog Voltage Reference Input 0 Pin 53 VOUT0 A Analog Buffered Analog Voltage Output – Channel 0 Pin 64 VOUT2 A Analog Buffered Analog Voltage Output – Channel 2 Pin 75 VOUT4 A Analog Buffered Analog Voltage Output – Channel 4 Pin 86 VOUT6 A Analog Buffered Analog Voltage Output – Channel 6 Pin 97 VSS — P Ground Reference Pin for all circuitries on the device 10, 11 8, 9 NC — — Not internally connected 12 10 VOUT7 A Analog Buffered Analog Voltage Output – Channel 7 Pin 13 11 VOUT5 A Analog Buffered Analog Voltage Output – Channel 5 Pin 14 12 VOUT3 A Analog Buffered Analog Voltage Output – Channel 3 Pin 15 13 VOUT1 A Analog Buffered Analog Voltage Output – Channel 1 Pin 16 14 VREF1 A Analog Voltage Reference Input 1 Pin 17 15 SDO I — SPI Serial Data Output Pin 18 16 SCK I ST SPI Serial Clock Pin 19 17 SDI I ST SPI Serial Data Input Pin 20 18 LAT0/HVC I ST DAC Register Latch/High-Voltage Command Pin. The Latch 0 pin allows the value in the volatile DAC0/DAC2/DAC4/DAC6 registers (wiper and Configuration bits) to be transferred to the DAC0/DAC2/DAC4/DAC6 outputs (VOUT0, VOUT2, VOUT4, VOUT6). The High-Voltage Command (HVC) allows user Configuration bits to be written. — 21 EP — — Exposed Thermal Pad Pin(1) Note 1: A = Analog, ST = Schmitt Trigger, HV = High Voltage, I = Input, O = Output, I/O = Input/Output, P = Power. |
