Electrical Characteristics (continued)

At AVDD = 10 V to 36 V, AVSS = –18 V to 0 V, AVDD + |AVSS|

≤ 36 V, GND = 0 V, REFIN = 5-V external, and DVDD = 2.7

V to 5.5 V. For VOUT: RL = 1 kΩ, CL = 200 pF; for IOUT: RL = 300 Ω. All specifications are from TA = –40°C to 125°C, unless

otherwise noted. Typical specifications are at 25°C.
