Circuit Options
The application circuit includes some optional components that may be required to improve tolerance of system
noise present in the application.
Dummy R source
may be added to the inverting input to provide a better matched source impedance at the input.
This will improve the rejection of common mode noise present within the system.
Dummy R load
may be added to the inverting output to provide better matched load at the output. This will reduce
the radiated EMI at the output and reduce the Output Noise present on the supply rail.
Rfilter
can be inserted between the Vcc in and the Vcc_out to provide additional filtering to the input Vcc. The input
Vcc powers the input bias reference only and can be a sensitive point to system noise. The nominal input current at
Vcc_IN s 0.35mA. An alternative would be to use an inductive choke.
C1
is additional Supply Filtering and should be added with Rfilter. The IC includes 10pF of on Chip Supply Filtering.
