GAINS OTHER THAN 20
The LMP8270 has an internal gain of +20; however, this gain can be modified. The signal path between the two
amplifiers is available as external pins.
GAINS LESS THAN 20
Figure 30 shows the configuration used to reduce the LMP8270 gain.

GAINS GREATER THAN 20
A higher gain can be achieved by using positive feedback on the second stage amplifier, A2, of LMP8270.
Figure 31 shows the configuration:
