5 / 16 page AD7245A/AD7248A REV. B –5– AD7245A PIN FUNCTION DESCRIPTIONS (DIP PIN NUMBERS) Pin Mnemonic Description lVSS Negative Supply Voltage (0 V for single supply operation). 2ROFS 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 DB11 Data Bit 11. Most Significant Bit (MSB). 6–11 DB10–DB5 Data Bit 10 to Data Bit 5. 12 DGND Digital Ground. 13–16 DB4–DB1 Data Bit 4 to Data Bit 1. 17 DB0 Data Bit 0. Least Significant Bit (LSB). 18 CS Chip Select Input (Active LOW). The device is selected when this input is active. Pin Mnemonic Description 19 WR Write Input (Active LOW). This is used in conjunction with CS to write data into the input latch of the AD7245A. 20 LDAC Load DAC Input (Active LOW). This is an asynchronous input which when active transfers data from the input latch to the DAC latch. 21 CLR Clear Input (Active LOW). When this input is active the contents of the DAC latch are reset to all 0s. 22 VDD Positive Supply Voltage. 23 RFB Feedback Resistor. This allows access to the amplifier’s feedback loop. 24 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.
