Data Sheet AD8555 ABSOLUTE MAXIMUM RATINGS Table 3. Parameter Rating Table 4.
Supply Voltage 6 V
Package Type θ 1 JA θJC Unit
Input Voltage VSS − 0.3 V to VDD + 0.3 V 8-Lead SOIC (R) 158 43 °C/W Differential Input Voltage1 ±5.0 V 16-Lead LFCSP (CP) 44 31.5 °C/W Output Short-Circuit Indefinite Duration to VSS or VDD 1 θJA is specified for the worst-case conditions, i.e., θJA is specified for device Storage Temperature Range −65°C to +150°C soldered in circuit board for SOIC and LFCSP packages. Operating Temperature Range −40°C to +125°C Junction Temperature Range −65°C to +150°C
ESD CAUTION
Lead Temperature Range 300°C (Soldering, 10 sec) 1 Differential input voltage is limited to ±5.0 V or ± the supply voltage, whichever is less. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. Rev.
