LT1055/LT1056 are precision, high speed JFET input operational amplifiers with very low bias current, offset voltage and drift.
The document describes the LT1055 and LT1056 as precision, high-speed JFET input operational amplifiers that combine low offset voltage with high slew rates. The LT1055 is designed for lower power dissipation to achieve lower bias and offset currents, while the LT1056 utilizes additional power for higher slew rate, bandwidth, and faster settling time.
| Offset Voltage (LT1055 H Package) | 150 µV Max –55°C to 125°C |
|---|---|
| Offset Drift (LT1055 H Package) | 4 µV/°C Max |
| Bias Current (LT1055 at 70°C) | 150pA Max |
| Slew Rate (Minimum) | 12V/µs |
The guaranteed maximum offset voltage for the LT1055 H Package is 150 µV over a temperature range of –55°C to 125°C.
These devices are suitable for precision instrumentation, logarithmic amplifiers, D/A output amplifiers, and photodiode amplifiers.
