Open Questions:\n\n1. Trimming the bridge.\n - Only makes sense w/ DC coupling\n - Bad tempco\n - Bad UX\n - Needed for significant gain\n\n2. AC vs DC Coupling; both have advantages: AC is easier\n\n3. Reducing R202,R203,R206,R207 to decrease Johnson noise: Probably useless.\n - Changing R202,R206 may break INAMP CMRR\n\n4. Use chopper amps in signal path: Probably bad\n - Lower total noise for *extremely* small bandwidths (<5Hz?)\n - Lower offset (if DC coupled)\n\n5. Driven shields for output: Probably useless\n - Reduce error due to leakage current\n - No analysis done to determine if this is significant\n - Current DAQ isn't likely to benefit

Open Questions:\n\n1. Trimming the bridge.\n - Only makes sense w/ DC coupling\n - Bad tempco\n - Bad UX\n - Needed for significant gain\n\n2. AC vs DC Coupling; both have advantages: AC is easier\n\n3. Reducing R202,R203,R206,R207 to decrease Johnson noise: Probably useless.\n - Changing R202,R206 may break INAMP CMRR\n\n4. Use chopper amps in signal path: Probably bad\n - Lower total noise for *extremely* small bandwidths (<5Hz?)\n - Lower offset (if DC coupled)\n\n5. Driven shields for output: Probably useless\n - Reduce error due to leakage current\n - No analysis done to determine if this is significant\n - Current DAQ isn't likely to benefit

Open Questions:\n\n1. Trimming the bridge.\n - Only makes sense w/ DC coupling\n - Bad tempco\n - Bad UX\n - Needed for significant gain\n\n2. AC vs DC Coupling; both have advantages: AC is easier\n\n3. Reducing R202,R203,R206,R207 to decrease Johnson noise: Probably useless.\n - Changing R202,R206 may break INAMP CMRR\n\n4. Use chopper amps in signal path: Probably bad\n - Lower total noise for *extremely* small bandwidths (<5Hz?)\n - Lower offset (if DC coupled)\n\n5. Driven shields for output: Probably useless\n - Reduce error due to leakage current\n - No analysis done to determine if this is significant\n - Current DAQ isn't likely to benefit
