7.5 Electrical Characteristics

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
