The LT1055/LT1056 JFET input operational amplifierscombine precision specifications with high speed performance. For the first time, 16V/µs slew rate and 6.5MHz gain-banwidth product are simultaneously achieved with offset voltage of typically 50µV, 1.2µV/°C drift, bias currents of40pA at 70°C and 500pA at 125°C. The 150µVmaximumoffset voltage specification is thebest available on any JFET input operational amplifier. The LT1055 and LT1056 are differentiated by their operat-ing currents. The lower power dissipation LT1055achieves lower bias and offset currents and offset voltage. Theadditional power dissipation of the LT1056 permits higherslew rate, bandwidth and faster settling time with a slightsacrifice in DC performance.

The voltage-to-frequency converter shown below is one ofthe many applications which utilize both the precision and high speed of the LT1055/LT1056. For a JFET input op amp with 23V/µs guaranteed slew rate,refer to the LT1022 data sheet.
