These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. TC14433/A ELECTRICAL SPECIFICATIONS Electrical Characteristics: Unless otherwise specified, VDD = +5V, VEE = -5V, C1 = 0.1 µF, (Mylar), C0 = 0.1 µF, RC = 300 kΩ, R1 = 470 kΩ @ VREF = 2V, R1 = 27 kΩ @ VREF = 200 mV, TA = +25°C.

Zero is recalculated during each conversion cycle. The meaningful specification is linearity. In other words, the deviation from correct reading for all inputs other than positive full scale and zero is defined as the linearity specification. 2: The LSD stability for 200 mV scale is defined as the range that the LSD will occupy 95% of the time. 3: Pin numbers refer to 24-pin PDIP. |
