Pin Configuration 24-Lead TSSOP (RU-24) Table 5. AD5440 Pin Function Descriptions Pin No. Mnemonic Function 1 AGND DAC Ground Pin. This pin should typically be tied to the analog ground of the system, but can be biased to achieve single-supply operation. 2, 24 IOUTA, IOUTB DAC Current Outputs. 3, 23 RFBA, RFBB DAC Feedback Resistor Pins. Establish voltage output for the DAC by connecting to an external amplifier output. 4, 22 VREFA, VREFB DAC Reference Voltage Input Terminals. 5 DGND Digital Ground Pin. 6 DAC A/B Selects DAC A or DAC B. Low selects DAC A; high selects DAC B. 7 to16 DB9 to DB0 Parallel Data Bits 9 Through 0. 19 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. 20 R/W Read/Write. When low, used in conjunction with CS to load parallel data. When high, used in conjunction with CS to read back contents of the DAC register. 21 VDD Positive Power Supply Input. This part can be operated from a supply of 2.5 V to 5.5 V. |
