Instrumentation Amp Is Smallest Available
Smaller than the tip of a pencil, the AD8235 instrumentation amplifier from Analog Devices is also presented as having up to 50% less power consumption than similar products. The 1.6 mm x 2.0 mm device operates with an input from 1.8 V to 5.5 V and draws 40 microamps (max) of current with a 6-nA shutdown current and a 40-pA bias current. The common-mode input-voltage range is 4 V and 1.4 V on 5-V and 1.8-V versions (respectively) suits battery-powered portable applications. A common-mode rejection ratio of 86 dB (gain=5) effectively eliminates common-mode interference. (From under $1 in 8-lead MSOP and 9-lead WLCSP configurations.
