Fig. 14-20 This circuit will withstand common-mode voltages of 1300 V and provide a CMRR of 160 dB or greater (see chapter 10 for coverage of common-mode voltages and CMRR). To trim, adjust R1 for 93 Hz at the LM301A output. Then, adjust the gain-trim pot for the desired gain. This amplifier is particularly useful for transducer signal conditioning, where high common-mode voltages mightexist. Linear Technology Linear Applications Handbook, 1990. p. AN6-2.
