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.
NOTES:

θ
JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
Electrical Specifications
INSTRUMENTATION AMPLIFIER “A” V+ = +5V, V- = GND, VCM = 1/2V+, TA = +25°C, unless otherwise
specified. For ISL28274 ONLY. Boldface limits apply over the operating temperature range, -40°C to +125°C,
temperature data established by characterization.
