DESCRIPTION
The LT®1055/LT1056 JFET input operational
amplifiers combine precision specifications with high speed performance. For the first time, 16V/µs slew rate and 6.5MHz gain bandwidth product are simultaneously achieved with offset
voltage of typically 50µV, 1.2µV/°C drift, bias currents of 40pA at 70°C and 500pA at 125°C. The 150µV maximum offset
voltage specification is the best available on any JFET input ope...
