6 / 16 page AD7245A/AD7248A REV. A –6– AD7248A PIN FUNCTION DESCRIPTION (ANY PACKAGE) Pin Mnemonic Description l VSS Negative Supply Voltage (0 V for single supply operation). 2 ROFS Bipolar Offset Resistor. This provides access to the on-chip application resistors and allows different output voltage ranges. 3 REF OUT Reference Output. The on-chip reference is provided at this pin and is used when configuring the part for bipolar outputs. 4 AGND Analog Ground. 5 DB7 Data Bit 7. 6 DB6 Data Bit 6. 7 DB5 Data Bit 5. 8 DB4 Data Bit 4. 9 DB3 Data Bit 3. 10 DGND Digital Ground. 11 DB2 Data Bit 2/Data Bit 10. 12 DB1 Data Bit 1/Data Bit 9. 13 DB0 Data Bit 0 (LSB)/Data Bit 8. Pin Mnemonic Description 14 CSMSB Chip Select Input for MS Nibble. (Active LOW). This selects the upper 4 bits of the input latch. Input data is right justified. 15 CSLSB Chip Select Input for LS byte. (Active LOW). This selects the lower 8 bits of the input latch. 16 WR Write Input. This is used in conjunction with CSMSB and CSLSB to load data into the input latch of the AD7248A. 17 LDAC Load DAC Input (Active LOW). This is an asynchronous input which when active transfers data from the input latch to the DAC latch. 18 VDD Positive Supply Voltage. 19 RFB Feedback Resistor. This allows access to the amplifier’s feedback loop. 20 VOUT Output Voltage. Three different output voltage ranges can be chosen: 0 V to +5 V, 0 V to +10 V or –5 V to +5 V.
