3 / 21 page ADS7800 3 SBAS001A www.ti.com SPECIFICATIONS (CONT) ELECTRICAL At TA = TMIN to TMAX, Sampling Frequency, fS, = 333kHz, –VS = –15V, VS = +5V, unless otherwise specified. ADS7800JP/JU/AH ADS7800KP/KU/BH PARAMETER CONDITIONS MIN TYP MAX MIN TYP MAX UNITS TEMPERATURE RANGE Specification JP/JU/KP/KU 0 +70 * * °C AH/BH –40 +85 * * °C Operating JP/KP/JU/KU –40 +85 * * °C Storage –65 +150 * * °C * Same as specification for ADS7800JP/JU/AH. NOTES: (1) Adjustable to zero with external potentiometer. (2) LSB means Least Significant Bit. For ADS7800, 1LSB = 2.44mV for the ±5V range, 1LSB = 4.88mV for the ±10V range. (3) Noise was characterized over temperature near full scale, 0V, and negative full scale. 0.1LSB represents a typical rms level of noise at the worst case, which was near full scale input at +125 °C. (4) All specifications in dB are referred to a full-scale input, either ±10V or ±5V. (5) For full scale step input, 12-bit accuracy attained in specified time. (6) Recovers to specified performance in specified time after 2 x FS input overvoltage.

The digital control inputs have a special FET struc- ture, which turns on when the input exceeds the supply by 18V, to minimize ESD damage. However, permanent damage may occur on unconnected devices subject to high energy electrostatic fields. When not in use, devices must be stored in conductive foam or shunts. The protective foam should be discharged to the destination socket before devices are re- moved.
