description
® The LT 1077 is a micro-power high-precision operational amplifier optimized for 5V single-supply operation. In addition, ± 15V specification is available.
The performance of a similar device is achieved at the cost of seriously degrading accuracy, noise, speed, and output driver specifications. The LT1077 reduces without sacrificing other parametric supply currents. The offset voltage reaches lowestof any micropower op amp. The bias current, voltage and current noise, slew rate, and gain bandwidth product are twenty times better than previous micropower op amps.
At 1/f angle of the voltage-noise spectrum at 0.7Hz. For anorder devices with higher amplitude supply currents, it can only find noise performance at low frequencies (0.1Hz to 10Hz).
The LT1077 is a high-precision operational amplifier that is fully plug-in compatible (including zeroing) with all industry standards. As a result, it can replace these precision op amps without sacrificing performance, but with significant energy savings.
The LT1077 can be operated from one lithium battery or two nickel-cadmium batteries. The input range is below ground. Full NPN output stage fluctuating ground, while sinking current without pull-down resistance is necessary.
For dual and quad op amps, see the LT1078/LT1079 datasheet for similar specifications.
