Nominal value +5 volts, ±5%. 1-9 DB0-DB11 Twelve Binary Data Bit inputs. DB11 17-19 is the MSB and DB0 is the LSB. 16 CE Chip Enable. Active low input. 15 CLR Active low digital input that clears the DAC register to zero, setting the DAC to minimum scale. 8 DGND Digital ground for input logic. 12 AGND Analog Ground. Ground reference for the internal bandgap reference voltage, the DAC, and the output buffer. 13 VOUT Voltage output from the DAC. Fixed output voltage range of 0 V to 4.095 V with 1 mV/LSB. An internal tempera- ture stabilized reference maintains a fixed full-scale voltage independent of time, temperature and power supply variations. 14 REFOUT Nominal 2.5 V reference output volt- age. This node must be buffered if re- quired to drive external loads. 11 NC No Connection. Leave pin floating.
