Depending on the state of RSTSEL, the DAC registers are set to either mid-scale or zero. 27 RSTSEL Reset select. Determines the action of RST. If high, an RST command sets the DAC registers to mid-scale (8000h). If low, an RST command sets the DAC registers to zero (0000h). 28 DGND Digital ground 29 VDD Digital +5V power supply 30 NC No connection 31 NC No connection 32 NC No connection 33 NC No connection 34 NC No connection 35 NC No connection PIN NAME DESCRIPTION 36 NC No connection 37 NC No connection 38 NC No connection 39 NC No connection 40 NC No connection 41 NC No connection 42 NC No connection 43 NC No connection 44 VOUTD Sense 2 Connect to VOUTD for bipolar mode 45 VOUTD Sense 1 Connect to VOUTD for unipolar mode 46 VOUTD DAC D output 47 NC No connection 48 NC No connection 49 Offset D Range 1 Connect to Offset D Range 2 for unipolar mode 50 Offset D Range 2 Connect to Offset D Range 1 for unipolar mode 51 Offset C Range 2 Connect to Offset C Range 1 for unipolar mode 52 Offset C Range 1 Connect to Offset C Range 2 for unipolar mode 53 VOUTC Sense 2 Connect to VOUTC for bipolar mode 54 VOUTC Sense 1 Connect to VOUTC for unipolar mode 55 VOUTC DAC C output 56 REF GND Reference ground 57 REF GND Reference ground 58 VOUTB DAC B output 59 VOUTB Sense 1 Connect to VOUTB for unipolar mode 60 VOUTB Sense 2 Connect to VOUTB for bipolar mode 61 Offset B Range 1 Connect to Offset B Range 2 for unipolar mode 62 Offset B Range 2 Connect to Offset B Range 1 for unipolar mode 63 Offset A Range 2 Connect to Offset A Range 1 for unipolar mode 64 Offset A Range 1 Connect to Offset A Range 2 for unipolar mode |
