Low frequency response
If a low frequency bandwidth limitation is required, it is possible to use input coupling
capacitors. In the low-frequency region, the input coupling capacitor Cin starts to have an
effect. Cin forms, with the input impedance Zin, a first order high-pass filter with a -3 dB cut-
off frequency (see Table 5 to Table 7).
So, for a desired cut-off frequency FCL, Cin is calculated as follows.
with FCL in Hz, Zin in Ω and Cin in F.
The input impedance Zin is for the whole power supply voltage range and it changes with the
gain setting. There is also a tolerance around the typical values (see Table 5 to Table 7).
