Operating Ratings indicate conditions for which the device is ensured to be functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Operation of the device beyond the maximum Operating Ratings is not recommended. (2) All voltages are measured with respect to GND = AGND = DGND = 0V, unless otherwise specified. Converter Electrical Characteristics Unless otherwise specified, the following specifications apply for AGND = DGND = DRGND = 0V, VA = VD = +3.3V, VDR= +2.5V, Internal VREF = +1.0V, fCLK = 65 MHz, fIN = 5 KHz, CL = 15 pF/pin. Boldface limits apply for TJ = TMIN to TMAX: all other limits TJ = 25°C (1) (2) (3) (4) Units Symbol Parameter Conditions Typical(5) Limits(5) (Limits) STATIC CONVERTER CHARACTERISTICS Resolution with No Missing Codes 12 Bits (min) INL Integral Non Linearity ±0.7 ±1.4 LSB (max) DNL Differential Non Linearity ±0.3 ±0.7 LSB (max) PGE Positive Gain Error ±1.5 ±3.5 %FS (max) NGE Negative Gain Error ±1.1 ±3.5 %FS (max) TC GE Gain Error Tempco −40°C ≤ TA ≤ +85°C 7.5 ppm/°C VOFF Offset Error (VIN+ = VIN−) ±0.06 ±0.75 %FS (max) TC VOFF Offset Error Tempco −40°C ≤ TA ≤ +85°C 4.4 ppm/°C Under Range Output Code 0 0 Over Range Output Code 4095 4095 (1) The inputs are protected as shown below. Input voltage magnitudes above VA or below GND will not damage this device, provided current is limited per. However, errors in the A/D conversion can occur if the input goes above VA or below GND by more than 100 mV. As an example, if VA is +3.3V, the full-scale input voltage must be ≤+3.4V to ensure accurate conversions. (2) To ensure accuracy, it is required that |VA–VD| ≤ 100 mV and separate bypass capacitors are used at each power supply pin. (3) With the test condition for VREF = +1.0V (2VP-P differential input), the 12-bit LSB is 488 µV. (4) When the input voltage at any pin exceeds the power supplies (that is, VIN < AGND, or VIN > VA), the current at that pin should be limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 25 mA to two. (5) Typical figures are at TA = 25°C, and represent most likely parametric norms at the time of product characterization. The typical specifications are not ensured. 6 Submit Documentation Feedback Copyright © 2005–2013, Texas Instruments Incorporated Product Folder Links: ADC12QS065 |
