10 / 41 page AC Electrical Characteristics (Continued) The following specifications apply for V + =V A+=VD+ = +5.0 VDC,VREF+ = +4.096 VDC,VREF−=0 VDC, 12-bit + sign conver- sion mode, t r =tf = 3 ns, fCK =fSK = 8 MHz for the ADC12H030, ADC12H032, ADC12H034 and ADC12H038, fCK =fSK =5 MHz for the ADC12030, ADC12032, ADC12034 and ADC12038, R S =25 Ω, source impedance for V REF+ and VREF− ≤ 25Ω, fully-differential input with fixed 2.048V common-mode voltage, and 10(t CK) acquisition time unless otherwise specified. Bold- face limits apply for T A =TJ =TMIN to TMAX; all other limits TA =TJ = 25˚C.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note 2: All voltages are measured with respect to GND, unless otherwise specified. Note 3: When the input voltage (VIN) at any pin exceeds the power supplies (VIN < GND or VIN > VA+orVD+), the current at that pin should be limited to 30 mA. The 120 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 30 mA to four. Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax, θJA and the ambient temperature, TA. The maximum allowable power dissipation at any temperature is PD =(TJmax − TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For this device, TJmax = 150˚C. The typical thermal resistance (θJA) of these parts when board mounted follow: Thermal Part Number Resistance θ JA ADC12H030CIWM, ADC12030CIWM 70˚C/W ADC12H032CIWM, ADC12032CIWM 64˚C/W ADC12H034CIN, ADC12034CIN 42˚C/W ADC12H034CIWM, ADC12034CIWM 57˚C/W ADC12H034CIMSA 97˚C/W ADC12H038CIWM, ADC12038CIWM 50˚C/W www.national.com 10 |
