NOTES
1Absolute maximum ratings are limiting values to be applied individually, and beyond which the service ability of the circuit may be impaired. 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: θJC = 1°C/W; θJA = 17°C/W (no air flow); θJA = 15°C/W
(air flow = 500 LFM). 68-pin ceramic LCC: θJC = 2.6°C/W; θJA = 15°C/W (no air flow); θJA = 13°C/W (air flow = 500 LFM).
33/4REF, 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 = +VSENSE
.
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 D0–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 +VS or –VS.
Specifications subject to change without notice.
