One input drift 0. 02 FtV / oC ', _, input bias current lOpAtr ,, input resistance loloQ, open loop gain isodB, these are 25 C standard parameters, ordinary differential amplifier is not so the parameter value. Instead, it's not very good opening characteristic AC conversion rate of 0. 5V / Us, GB volume of sookHz, the input conversion noise is in DC ~ 10Hz narrowband taken off, the level of 1 - iuv, - , (. ,,, 1 plus low-pass filter for the crossing is a prerequisite.
