DESCRIPTION

The LT1055/LT1056 JFET input operational amplifiers

combine precision specifications with high speed perfor-

mance.

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

width product are simultaneously achieved with offset

voltage of typically 50 V, 1.2 V/ C drift, bias currents of

40pA at 70 C and 500pA at 125 C.

The 150 V maximum offset voltage specification is the

best available on any JFET input operational amplifier.

The LT1055 and LT1056 are differentiated by their operat-

ing 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.

For a JFET input op amp with 23V/ s guaranteed slew rate,

refer to the LT1022 data sheet.
