LT1001 Precision Operational Amplifier DESCRIPTION
®1001 significantly advances state-of-theart precision operational amplifiers. design, processing, testing device, particular attention been paid optimization entire distribution several parameters. Consequently, specifications lowest cost, commercial temperature device, LT1001C, have been dramatically improved when compared equivalent grades competing precision amplifiers. Essentially, input offset voltage units less than 50µV (see distribution plot below). This allows LT1001AM/883 specified 15µV. Input bias offset currents, common-mode power supply rejection LT1001C offer guaranteed performance which were previously attainable only with expensive, selected grades other devices. Power dissipation nearly halved compared most popular precision amps, without adversely affecting noise speed performance. beneficial by-product lower dissipation decreased warm-up drift. Output drive capability LT1001 also enhanced with voltage gain guaranteed load current. similar performance dual precision amp, with guaranteed matching specifications, LT1002. Shown below platinum resistance thermometer application.

Offset Voltage Adjustment
input offset voltage LT1001, drift with temperature, permanently trimmed wafer test level. However, further adjustment necessary, nulling with potentiometer will degrade drift with temperature. Trimming value other than zero creates drift (Vos/ 300)µV/°C, e.g., adjusted change drift will µV/°C. adjustment range with approximately ±2.5mV. less adjustment range needed, sensitivity resolution nulling improved using smaller conjunction with fixed resistors. example below approximate null range ±100
