... Digital Communications indicate overflow conditions. Output data format is straight binary. Power dissipation is very low at only 1.0 watt with power supply voltages of +5.0 and -5.2 volts. The SPT7820 also provides a wide input voltage swing of 2.0 volts. The SPT7820 is available in 28-lead ceramic sidebrazed DIP, PDIP and SOIC packages over the commercial, industrial and military temperature ranges ...

... The CLK pulse width (tpwH) must be kept between 20 ns and 300 ns to ensure proper operation of the internal track-and- hold amplifier. (See timing diagram.) When operating the SPT7820 at sampling rates above 3 MSPS recom mended that the clock input duty cycle be kept at 50% but performance will not be degraded if kept within the range of 40-60% ...
