Therefore, the output data from these modes are not an indication of the accuracy of a conversion result. (2) Two on-chip diodes are tied to each analog input through a series resistor as shown below. Input voltage magnitude up to 5V above VA+ or 5V below GND will not damage this device. However, errors in conversion can occur (if these diodes are forward biased by more than 50 mV) if the input voltage magnitude of selected or unselected analog input go above VA+ or below GND by more than 50 mV. As an example, if VA+ is 4.5 VDC, full-scale input voltage must be ≤4.55 VDC to ensure accurate conversions. (3) To ensure accuracy, it is required that the VA+ and VD+ be connected together to the same power supply with separate bypass capacitors at each V+ pin. (4) With the test condition for VREF (VREF+ − VREF−) given as +4.096V, the 12-bit LSB is 1.0 mV. For VREF = 2.5V, the 12-bit LSB is 610 μV. (5) Typical figures are at TJ = TA = 25°C and represent most likely parametric norm. (6) Tested limits are specified to TI's AOQL (Average Outgoing Quality Level). 8 Submit Documentation Feedback Copyright © 2000–2013, Texas Instruments Incorporated Product Folder Links: ADC12130 ADC12132 ADC12138 |
