The AD8221ARM Matches the Performance but is $2.00 LESS and half the size! The AD8221 vs. the LT1167 over Frequency The AD8221 rejects common mode voltage on its inputs better than the LT1167. @ 10KHz 31dB Delta! At 10Khz: AD8221 CMR is 95dB. LT1167 CMR is 64dB. That is a difference of 31 dB. That means that the AD8221 performs 30X better than the LT1167 in rejecting common mode voltage. (ex at 10KHz) Compare the CMRR Performance Side by Side +15 20V p-p @ 10KHz AD8221 Gain=1 G=1 Output -15 LT1167 Gain=1 Input Signal (10V Scale) Common Mode Error at the Output (10mV Scale) AD8221 common mode error = 0.450mV LT1167 common mode error = 13.5mV The LT1167 gives you 30x the error at a higher cost!
