I would like to know the amplifier and ADC for data acquisition from my sensor. The amplifier is required to have:Minimal full scale input: +/- 3 mVMaximum full scale input: 1000 mVOutput: Voltage between +3 and -3 VoltStandard Amplification between 1 and 1000Input impedance: 1 MohmZero drift at output: < 0.05 mV/CRange drift at output: < 20 ppm/COutput impedance: < 10 ohmResponse time: <1s
I also would like to know the ADC with this amplifier and the possibility of an integrated circuit of amplifier and ADC for data acquisition.
I cannot find any amplifier which fits all your requirements.
The 50uV/C output offset drift number (and the gain TC) you've mentioned, limits you to only two Instrumentation Amplifiers:
At maximum gain of 1,000V/V, this translates to input offset drift of 50nV/C.
Even then, you may have difficulty meeting the 20ppm/C gain drift with these devices at the maximum gain of 1,000V/V.
AD8231: 30ppm/C (G = 128V/V)
AD8230: 60ppm/C (G = 1,002V/V)
As far as the ADC is concerned, you may have to be more specific on what your requirements are? Accuracy level, # of bits, sampling rate, etc.
For example, LTC1274 (12 bit, single channel, single-ended input, +/-5V supplies).
