This pin should normally be tied to the analog ground of the system. 31 GND Ground Pin. 4–15 2–13 DB11–DB0 Parallel Data Bits 11 to 0. 16 14 CS Chip Select Input. Active low. Rising edge of CS loads data. Used in conjunction with R/W to load parallel data to the input latch or to read data from the DAC register. 17 15 R/ W Read/Write. When low, used in conjunction with CS to load parallel data. When high, use with CS to readback contents of DAC register. 18 16 VDD Positive Power Supply Input. These parts can be operated from a supply of +2.5 V to +5.5 V. 19 17 VREF DAC Reference Voltage Input Terminal. 20 18 RFB DAC Feedback Resistor Pin. Establish voltage output for the DAC by connecting to external amplifier output. |
