AD8429 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 2. THERMAL RESISTANCE Parameter Rating
θJA is specified for a device in free air using a 4-layer JEDEC Supply Voltage ±18 V printed circuit board (PCB). Output Short-Circuit Current Duration Indefinite Maximum Voltage at –IN, +IN1 ±VS
Table 3.
Differential Input Voltage1
Package θJA Unit
Gain ≤ 4 ±VS 8-Lead SOIC 121 °C/W 4 > Gain > 50 ±50 V/gain Gain ≥ 50 ±1 V Maximum Voltage at REF ±V
ESD CAUTION
S Storage Temperature Range −65°C to +150°C Specified Temperature Range −40°C to +125°C Maximum Junction Temperature 140°C ESD Human Body Model 3.0 kV Charge Device Model 1.5 kV Machine Model 0.2 kV 1 For voltages beyond these limits, use input protection resistors. See the Theory of Operation section for more information. 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.
