Figure 6-12 is similar to Fig. 6-1, except for the op-amp characteristics. For the LT1028, the input voltage-noise density is 1.1 nV√Hz maximum at 1 kHz, 0.85 nV√Hz typical at 1 kHz, 1.0 nV√Hz typical at 10 Hz, and 35 nVp-p typical at 0.1 Hz to 10 Hz. Minimum gain-bandwidth is 50 MHz, minimum slew rate is 10 V/μs, maximum offset voltage is 40 μV, and maximum offset drift is 0.8 μV/℃. Minimum voltage gain is 7 million.
