description
® The LT 1077 is a micropower high precision op amp optimized for 5V single supply operation. In addition, ± 15V specifications are available.
The performance of micro-comparable devices is achieved at the expense of serious and degrading accuracy, noise, speed, and output driver specifications. The LT1077 reduces supply current without sacrificing other parameters. The offset voltage reaches Lowestof any micropower op amp. Bias current, voltage and current noise, slew rate, and gain-bandwidth product are twenty times better, better than previous micropower op amps.
At a voltage noise spectrum of 0.7Hz at an angle of 1/f. For ANORDER devices with higher supply currents, it can only find this result in noise performance at low frequencies (0.1Hz to 10Hz).
The LT1077 is a fully plug-compatible (including zeroing) and full industry standard high precision op amp. As a result, it can replace these precision op amps in many applications 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 fluctuations to ground, while sinking current without pull-down resistors is necessary.
For dual and quad op amps with similar specifications, see the LT1078/LT1079 datasheet.
