This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. 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, VS- = GND, VCM = 1/2VS+ TA = +25°C, unless otherwise specified. For ISL28274 ONLY. Boldface limits apply over the operating temperature range, -40°C to +125°C.
