... V/ C drift, 130dB common mode and power supply rejection and 7.2MHz gain bandwidth product. The com- mon mode range exceeds the power supply by 100mV. The voltage gain of the LT1677 is extremely high, especially with a single supply: 20 million driving a 1k 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 ...

... LT1677 Noise Testing The 0.1Hz to 10Hz peak-to-peak noise of the LT1677 is measured in the test circuit shown (Figure 6a). The fre- quency response of this noise tester (Figure 6b) indicates that the 0.1Hz corner is defined by only one zero. The test time to measure 0.1Hz to 10Hz noise should not exceed ...
