VSS – 0.3V to VDD + 0.3V Current at Input Pins ......................................... ±2 mA Current at Supply Pins .................................... ±50 mA Current at Output Pins .................................... ±25 mA Storage temperature .......................... -65°C to +150°C Ambient temp. with power applied ..... -55°C to +125°C ESD protection on all pins 4 kV (HBM), 400V (MM) Maximum Junction Temperature (TJ)................+150°C † Notice: Stresses above those listed under “Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, VDD = 5V, VSS = 0V, VREF = 2.048V, Output Buffer Gain (G) = 2x, RL = 5 k to GND, CL = 100 pF, TA = -40 to +85°C. Typical values are at +25°C. Parameters Sym Min Typ Max Units Conditions Power Requirements Input Voltage VDD 2.7 — 5.5 V Input Current IDD — 415 750 µA All digital inputs are grounded, all analog outputs (VOUT) are unloaded.
