DescriptionThe INA128U is designed as one kind of low power, general purpose instrumentation amplifiers offering excellent accuracy.It provides an industry standard gain equation and operates with power supplies as low as ±2.25V, and quiescent current is only 700mA-ideal for battery operated systems. Internal input protection can withstand up to ±40V without damage.Also it can be used in bridge amplifier,thermocouple amplifier,rtd sensor amplifier,medical instrum-entation and data acquisition.
Features of the INA128U are:(1)low offset voltage:50mv max;(2)low drift:0.5mv/°c max;(3)low input bias current:5na max;(4)high cmr:120db min;(5)inputs protected to ±40v;(6)wide supply range:±2.25 to ±18 V;(7)low quiescent current:700mA;(8)8-pin plastic dip,so-8.
The absolute maximum ratings of the INA128U can be summarized as:(1)supply voltage:±18V;(2)analog input voltage range:±40V;(3)output short-circuit (to ground):continuous;(4)operating temperature:-40°C to +125°C;(5)storage temperature:-40°C to +125°C;(6)junction temperature:+150°C;(7)lead temperature (soldering, 10s):+300°C.If you want to know more information such as the electrical characteristics about the INA128U,please download the datasheet in www.seekic.com or www.chinaicmart.com .
