The AD830 differential input amplifier has a reasonably high bandwidth (85MHz at unity gain) and can easily be configured for an input dc offset of in the (-5V to +5V) range as its input common mode range is (-12, +12.8). However it only has a linear input range of about 2V and the input noise is around 30nV/rtHz. Gain is set by a pair of resistors.
