Data Sheet AD8428 ABSOLUTE MAXIMUM RATINGS Table 3. THERMAL RESISTANCE Parameter Rating
θJA is specified for the worst-case conditions, that is, a device Supply Voltage ±18 V soldered in a circuit board for surface-mount packages. Output Short-Circuit Current Duration Indefinite
Table 4. Thermal Resistance
Maximum Voltage at −IN, +IN1 ±VS
Package θ
Maximum Voltage at −FIL, +FIL ±V
JA Unit
S Differential Input Voltage1 ±1 V 8-Lead SOIC_N 121 °C/W Maximum Voltage at REF ±VS Storage Temperature Range −65°C to +150°C
ESD CAUTION
Specified Temperature Range −40°C to +85°C Maximum Junction Temperature 140°C ESD Human Body Model 5000 V Charged Device Model 1250 V Machine Model 400 V 1 For voltages beyond these limits, use input protection resistors. See the Input Protection section for more information. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Rev.
