That's another reason to choose the LTC6240 over the LT1793. Beside the smaller 1/f noise (0.55µVpp vs 2.4µVpp), the LTC6240 has a much lower temperature coefficient (0.7µV/°C vs 8µV/°C). The biggest drawback of the LT6240HV is its limited input range of -5V to +3V (for a +/-5V supply). But in an integrator application, this shouldn't be a problem (phase reversal is prevented by the 10k input resistor).
