Data Sheet AD8235 ABSOLUTE MAXIMUM RATINGS Table 3. Parameter Rating THERMAL RESISTANCE
Supply Voltage 6 V Output Short-Circuit Current 55 mA θJA is specified for the worst-case conditions, that is, a device Input Voltage (Common Mode) ±V soldered in a circuit board for surface-mount packages. This S was measured using a standard 4-layer board, unless otherwise Differential Input Voltage ±VS specified. Storage Temperature Range −65°C to +125°C Operating Temperature Range −40°C to +125°C
