2 / 29 page ADS5424 SLWS157B − JANUARY 2005 − REVISED JANUARY 2010 www.ti.com 2 NOTE: For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI Web site at www.ti.com. ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range unless otherwise noted(1) ADS5424 UNIT AVDD to GND 6 Supply voltage DRVDD to GND 5 V Analog input to GND −0.3 to AVDD + 0.3 V Clock input to GND −0.3 to AVDD + 0.3 V CLK to CLK ±2.5 V Digital data output to GND −0.3 to DRVDD + 0.3 V Operating temperature range −40 to 85 °C Maximum junction temperature 150 °C Storage temperature range −65 to 150 °C (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. THERMAL CHARACTERISTICS(1) PARAMETER TEST CONDITIONS TYP UNIT θJA Soldered slug, no airflow 22.5 °C/W θJA Soldered slug, 200-LPFM airflow 15.8 °C/W θJA Unsoldered slug, no airflow 33.3 °C/W θJA Unsoldered slug, 200-LPFM airflow 25.9 °C/W θJC Bottom of package (heatslug) 2 °C/W (1) Using 25 thermal vias (5 x 5 array). See the Application Section. This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because small parametric changes could cause the device not to meet its published specifications. RECOMMENDED OPERATING CONDITIONS PARAMETER MIN TYP MAX UNIT Supplies Analog supply voltage, AVDD 4.75 5 5.25 V Output driver supply voltage, DRVDD 3 3.3 3.6 V Analog Input Differential input range 2.2 VPP Input common-mode voltage, VCM 2.4 V Digital Output Maximum output load 10 pF Clock Input ADCLK input sample rate (sine wave) 1/tC 30 105 MSPS Clock amplitude, sine wave, differential(1) 3 VPP Clock duty cycle(2) 50% Open free-air temperature range −40 85 °C (1) See Figure 22 and Figure 23 for more information. (2) See Figure 21 for more information. |
