Product Descriptions
The LT1055/LT1056 JFET input operational amplifiers combine precision specifications with high speed performance.
For the first time in an SO package, 14Vlus slew rate and 5.5MHz gain-bandwidth product are simultaneously achieved with offset voltage of typically 0.5mV, 4uV/°C drift, and bias currents of 60pA at 70°C.
The 1.5mV maximum offset voltage specification is the best available on any JFET input operational amplifier in the plastic S0 package.
The LT1055 and LT1056 are differentiated by their operating currents. The lower power dissipation LT1055 achieves lower bias and offset currents and offset voltage. The additional power dissipation of the LT1056 permits higher slew rate, bandwidth and faster settling time with a slight sacrifice in DC performance.
The voltage to frequency converter shown below is one of the many applications which utilize both the precision and high speed of the LT1055/LT1056.
