CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
Analog Specifications Across recommended operating conditions unless otherwise stated. Boldface limits apply across the operating
temperature range, -40°C to +85°C.
