■

Guaranteed Drift

■

Guaranteed Bias Current

For the first time, 16V/µs slew rate and 6.5MHz gain-ban-

width 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.

Guaranteed Slew Rate

■

The 150µV maximum offset voltage specification is the

best available on any JFET input operational amplifier.

APPLICATIONS

The LT1055 and LT1056 are differentiated by their operat-

ingcurrents.ThelowerpowerdissipationLT1055achieves

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.
