INA120 INSTRUMENTATION AMPLIFIER

The INA120 is a precision instrumentation amplifier ideal for accurate signal acquisition. It combines precision, protected-input operational amplifiers, lasertrimmed gain-setting resistors, and a high commonmode rejection difference amplifier on a single chip. Simple pin-strapped connections set precise gains of 1, 10, 100 or 1000. External resistors can be.
