In the design,processing, and testing of the device, particular atten-tion has been paid to the optimization of the entiredistribution of several key parameters. Consequently,the specifications of the lowest cost, commercial tem-perature device, the LT1001C, have been dramaticallyimproved when compared to equivalent grades of com-peting precision , the input offset voltage of all units is lessthan 50 V (see distribution plot below).

2 This allows theLT1001AM/883 to be specified at 15 V. Input bias andoffset currents, common-mode and power supply re-jection of the LT1001C offer guaranteed performancewhich were previously attainable only with expensive,selected grades of other devices. Power dissipation isnearly halved compared to the most popular precisionop amps, without adversely affecting noise or speedperformance. A beneficial by-product of lower dissipa-tion is decreased warm-up drift. Output drive capabilityof the lt1001 is also enhanced with voltage gainguaranteed at 10 mA of load current. For similar perfor-mance in a dual precision op amp, with guaranteedmatching specifications, see the LT1002.
