8.2.5 Differential Line Receiver With AC-Coupled Outputs
Figure 8-7 shows the OPA1678 used as an integrator that drives the reference pin of the INA1650, which forces the output dc voltage to 0 V. This configuration is an alternative to large ac-coupling capacitors that can distort at high output levels. The low input bias current and low input offset voltage of the OPA1678 make the device an excellent choice for integrator applications.
