LT1677 - Low Noise, Rail-to-Rail Precision Op Amp

The voltage gain of the LT1677 is extremely high, 19 million (typical) driving a 10k load.

In the design, processing and testing of the device, particular attention has been paid to the optimization of the entire distribution of several key parameters. Consequently, the specifications have been spectacularly improved compared to competing rail-to-rail amplifiers.
