Functional operability is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability. 2Typical thermal impedances (part soldered onto board): 68-pin leaded ceramic chip carrier: θ JC = 1°C/W; θJA = 17°C/W (no air flow); θJA = 15°C/W (air flow = 500 LFM). 68-pin ceramic LCC: θ JC = 2.6°C/W; θJA = 15°C/W (no air flow); θJA = 13°C/W (air flow = 500 LFM). 33/4 REF, 1/2REF, and 1/4REF reference ladder taps are driven from dc sources at +0.875 V, 0 V, and –0.875 V, respectively. Accuracy of the overflow comparator is not tested and not included in linearity specifications. 4Measured with ANALOG IN = +V SENSE. 5Output delay measured as worst-case time from 50% point of the rising edge of ENCODE to 50% point of the slowest rising or falling edge of D 0–D9. Output skew measured as worst-case difference in output delay among D 0–D9. 6RMS signal to rms noise with analog input signal 1 dB below full scale at specified frequency. 7Intermodulation measured with analog input frequencies of 2.3 MHz and 3.0 MHz at 7 dB below full scale. 8Measured as the ratio of the worst-case change in transition voltage of a single comparator for a 5% change in +V S or –VS. Specifications subject to change without notice. REV. A –3– AD9020 |
