6 / 8 page  ® ® ADS-119 6 Figure 6. ADS-119 Grounded Input Histogram Figure 7. ADS-119 FFT Analysis This histogram represents the typical peak-to-peak noise (including quantization noise) associated with the ADS-119. 4,096 conversions were processed with the input to the ADS-119 tied to analog ground. THERMAL REQUIREMENTS All DATEL sampling A/D converters are fully characterized and specified over operating temperature (case) ranges of 0 to +70°C and –55 to +125°C. All room-temperature (TA = +25°C) production testing is performed without the use of heat sinks or forced-air cooling. Thermal impedance figures for each device are listed in their respective specification tables. These devices do not normally require heat sinks, however, standard precautionary design and layout procedures should be used to ensure devices do not overheat. The ground and power planes beneath the package, as well as all pcb signal runs to and from the device, should be as heavy as possible to help conduct heat away from the package. Electrically- insulating, thermally-conductive "pads" may be installed underneath the package. Devices should be soldered to boards rather than "socketed", and of course, minimal air flow over the surface can greatly help reduce the package temperature. In more severe ambient conditions, the package/junction temperature of a given device can be reduced dramatically (typically 35%) by using one of DATEL's HS Series heat sinks. See Ordering Information for the assigned part number. See page 1-183 of the DATEL Data Acquisition Components Catalog for more information on the HS Series. Request DATEL Application Note AN-8, "Heat Sinks for DIP Data Converters", or contact DATEL directly, for additional information. 3000 2500 2000 1500 1000 500 0 Digital Output Code 0 –10 –20 –30 –40 –50 –60 –70 –80 –90 –100 –110 –120 –130 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 Frequency (MHz) (fs = 10MHz, fin = 4.9MHz, Vin = –0.5dB, 4,096-point FFT) |
