4 / 8 page  Pin Assignment LC89080Q (QFP48A) No. 4030-4/8 LC89080, 89080Q Pin No. Symbol Description 1 to 3 DA5 to 7 Channel A digital input 4 DA8 Channel A digital input (LSB) 5 DB1 Channel B digital input (MSB) 6 NC Unused (no connection) 7 to 12 DB2 to DB7 Channel B digital input 13 DB8 Channel B digital input (LSB) 14 DC1 Channel C digital input (MSB) 15 to 18 DC2 to DC5 Channel C digital input 19 DVDD Digital system power supply (+5 V) 20 DC6 Channel C digital input 21 DC7 Channel C digital input 22 DC8 Channel C digital input (LSB) 23 CLK Clock input 24 NC Unused (no connection) 25 DVDD Digital system power supply (+5 V) 26 DGND Digital system ground (0 V) 27 ICOB Channel C negative output. Connect to A.GND through an output resistor RO (usually 75 Ω). 28 ICO Channel C positive output. Connect to A.GND through an output resistor RO (usually 75 Ω). 29 AVDD Analog system power supply (+5 V) 30 AVDD Analog system power supply (+5 V) 31 IBOB Channel B negative output. Connect to A.GND through an output resistor RO (usually 75 Ω). 32 IBO Channel B positive output. Connect to A.GND through an output resistor RO (usually 75 Ω). 33 AGND Analog system ground (0 V) 34 IAOB Channel A negative output. Connect to A.GND through an output resistor RO (usually 75 Ω). 35 IAO Channel A positive output. Connect to A.GND through an output resistor RO (usually 75 Ω). 36 AVDD Analog system power supply (+5 V) 37 COMP Phase compensation capacitor. Connect a 1 µF capacitor between this pin and ground. 38 NC Unused (no connection) 39 IREF Reference current output. Connect a resistor that is 4 times the output resistance RO to this pin. 40 VREFIN Reference voltage input. This input pin sets the analog output dynamic range. 41 VREFOUT Reference voltage output. The output voltage is set to 0.2 times VDD by a resistor divider. When VDD is 5.0 V, a 1.0 V reference voltage can be acquired from pin 40. 42 DGND Digital system ground (0 V) 43 DVDD Digital system power supply (+5 V) 44 DVDD Digital system power supply (+5 V) 45 DA1 Channel A digital input (MSB) 46 to 48 DA2 to DA4 Channel A digital input |
