LT1055/LT1056
Precision, High Speed,
JFET Input Operational Amplifiers
FEATURES DESCRIPTION Guaranteed Offset Voltage: 150µV Max –55°C to 125°C: 500µV Max
nn Guaranteed Drift: 4µV/°C Max
nn Guaranteed Bias Current 70°C: 150pA Max 125°C: 2.5nA Max
nn Guaranteed Slew Rate: 12V/µs Min
nn Available in 8-Pin PDIP and SO Packages The LT®1055/LT1056 JFET input operational amplifiers
combine precision specifications with high speed performance. nn For the first time, 16V/µs slew rate and 6.5MHz gain
bandwidth 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.
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 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. Precision, High Speed Instrumentation
