2 / 34 page ABSOLUTE MAXIMUM RATINGS (1) (2) ELECTRICAL CHARACTERISTICS ADS8512 SLAS485 – JUNE 2008 ...................................................................................................................................................................................................... www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

PARAMETER UNIT R1IN ±25 V R2IN ±25 V Analog inputs R3IN ±25 V REF VS + 0.3 V to GND – 0.3 V GND ±0.3 V Ground voltage differences VS 6 V Digital inputs –0.3 V to VS + 0.3 V Maximum junction temperature +165°C Storage temperature range –65°C to +150°C Internal power dissipation 700 mW Lead temperature (soldering, 1,6 mm from case, 10 seconds) +260°C (1) Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to absolute maximum conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal. At TA = -40°C to +85°C, fS = 40 kHz, VS = 5 V, and using internal reference and fixed resistors, unless otherwise specified.
