DATASHEET ISL28118M FN7858 Rev 1.00 40V Extended Temperature Range, Precision Single-Supply, Rail-to-Rail Output, March 7, 2014 Operational Amplifier The ISL28118M is a single, low-power precision amplifier Features optimized for single-supply applications over the extended Rail-to-rail output <10mV temperature range of -55C to +125C. This device features a Below-ground (V-) input capability to -0.5V common mode input voltage range extending to 0.5V below the V- rail, a rail-to-rail differential input voltage range for use Rail-to-rail input differential voltage range for comparator as a comparator, and rail-to-rail output voltage swing, which applications makes it ideal for single-supply applications where input Single-supply range 3V to 40V operation at ground is important. Low current consumption 850A The ISL28118M features low power, low offset voltage, and Low noise voltage . 5.6nV/Hz low temperature drift, making it the ideal choice for Low noise current . 355fA/Hz applications requiring both high DC accuracy and AC performance. The op amp is designed to operate over a single Low input offset voltage 150V Max. supply range of 3V to 40V or a split supply voltage range of Superb offset voltage temperature drift 1.2V/C, Max. +1.8V/-1.2V to 20V. The combination of precision and small Operating temperature range -55C to +125C footprint provides the user with outstanding value and flexibility relative to similar competitive parts. No phase reversal Applications include precision instrumentation, data Applications acquisition, precision power supply controls, and industrial controls. Precision instruments Medical instrumentation The ISL28118M is offered in the 8 Ld MSOP package and operate over the extended temperature range of -55C to Data acquisition +125C.
