Electrical Characteristics (continued)

Minimum and maximum specifications are at TA = –40°C to +85°C. Typical specifications are at TA = +25°C, AVDD = +2.5 V,

AVSS = –2.5 V, fCLK = 4.096 MHz, VREF = 5 V, and DVDD = 3.3 V (unless otherwise noted). Refer to Figure 50. DAC1282A

supports gains = 1/1, 1/4, and 1/16 only.
