Figures 2 and 3 show single-ended and differential AC-
coupled input circuits. Each of the amplifier inputs is
internally biased to a 2.35V reference through a 20k
resistor, eliminating external DC bias circuits. A series
0.1F capacitor is required at each amplifier input for
AC-coupled signals.
When operating with AC-coupled inputs, the input
amplifiers’ DC offset voltage is nulled to within ±1/2LSB
by an on-chip offset-correction amplifier. An external
compensation capacitor is required to set the dominant
pole of the offset-correction amplifier’s frequency
response (Figures 2 and 3). The compensation capaci-
tor determines the low-frequency corner of the analog
input response according to the following formula:
fc = 1 / (0.1 x C)
where C is the value of the compensation capacitor in
F, and fc is the corner frequency in Hz.
