The INA125 is a low power, high accuracy instrumentaTIonamplifier with a precision voltage reference. Itprovides complete bridge excitaTIon and precision differenTIal-input amplificaTIon on a single integratedcircuit.A single external resistor sets any gain from 4 to10,000. The INA125 is laser-trimmed for low offsetvoltage (250mV), low offset drift (2mV/°C), and highcommon-mode rejection (100dB at G = 100). It operateson single (+2.7V to +36V) or dual (±1.35V to±18V) supplies.The voltage reference is externally adjustable with pinselectablevoltages of 2.5V, 5V, or 10V, allowing usewith a variety of transducers. The reference voltage isaccurate to ±0.5% (max) with ±35ppm/°C drift (max).Sleep mode allows shutdown and duty cycle operationto save power.The INA125 is available in 16-pin plastic DIP andSO-16 surface-mount packages and is specified forthe –40°C to +85°C industrial temperature range.
