AD5424 Pin Function Descriptions Pin No. TSSOP LFCSP Mnemonic Description 1 19 IOUT1 DAC Current Output. 2 20 IOUT2 DAC Analog Ground. This pin should normally be tied to the analog ground of the system. 3 1 GND Ground. 4–11 2–9 DB7–DB0 Parallel Data Bits 7 to 0. 10–13 NC No Internal Connection. 12 14 CS Chip Select Input. Active low. Used in conjunction with R/W to load parallel data to the input latch or to read data from the DAC register. Rising edge of CS loads data. 13 15 R/W Read/Write. When low, use in conjunction with CS to load parallel data. When high, use with CS to read back contents of DAC register. 14 16 VDD Positive Power Supply Input. These parts can be operated from a supply of 2.5 V to 5.5 V. 15 17 VREF DAC Reference Voltage Input Terminal. 16 18 RFB DAC Feedback Resistor Pin. Establish voltage output for the DAC by connecting to external amplifier output. |
