the ina129 is a low power general purpose instrumentation amplifier offering excellent accuracy. the versatile three operational amplifier design and small size make it ideal for a wide range of applications. current-feedback input circuitry provides wide bandwidth even at high gain. a single external resistor sets any gain from 1 to 10 000. the ina129 gain equation is compatible with the ad620. the ina129 is laser trimmed for very low offset voltage (50 v) and high common-mode rejection (93 db at g = 100). it operates with power supplies as low as 2.25 v and quiescent current of 2 ma - typically. internal input protection can withstand up to 40 v without damage. the ina129 is available in 8-pin ceramic dip and 8-pin ceramic surface-mount packages specified for the 55c to 210c temperature range.
