5 / 8 page ![]() RH1498M 5 rh1498mfc Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: A heat sink may be required to keep the junction temperature below this absolute maximum rating when the output is shorted indefinitely. Note 3: Matching parameters are the difference between amplifiers A and B. Note 4: Output voltage swings are measured between the output and power supply rails.
