40V Precision Single Supply Rail-to-Rail Output Low Power Operational Amplifiers ISL28118, ISL28218 The ISL28118 and ISL28218 are single and dual precision, single supply rail-to-rail output amplifiers with a common mode input voltage range extending to 0.5V below the V- rail. These op amps feature low power, low offset voltage, and low temperature drift, making them the ideal choice for applications requiring both high DC accuracy and AC performance. The devices can operate from single (3V to 40V) or dual (±1.5V to ±20V) supplies. The combination of precision and small footprint provides the user with outstanding value and flexibility relative to similar competitive parts. Applications for these amplifiers include precision instrumentation, data acquisition, precision power supply controls, and industrial controls. Both parts are offered in 8 Ld TDFN, 8 Ld SOIC and 8 Ld MSOP packages. All devices are offered in standard pin configurations and operate over the extended temperature range of -40°C to +125°C.
