LT1055/LT1056

Precision, High Speed,

JFET Input Operational Amplifiers

DESCRIPTIO

FEATURES

The LT^®1055/LT1056 JFET input operational amplifiers

combineprecisionspecificationswithhighspeedperfor-

mance.

■

Guaranteed Offset Voltage: 150µV Max

–55°C to 125°C: 500µV Max

■

Guaranteed Drift: 4µV/°C Max

Guaranteed Bias Current

■

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

bandwidth product are simultaneously achieved with off-

set voltage of typically 50µV, 1.2µV/°C drift, bias currents

of 40pA at 70°C and 500pA at 125°C.

70°C: 150pA Max

125°C: 2.5nA Max

■

Guaranteed Slew Rate: 12V/µs Min

■

Available in 8-Pin PDIP and SO Packages

The 150µV maximum offset voltage specification is the

best available on any JFET input operational amplifier.

APPLICATIO S

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.
