The INA104 is a high accuracy, multistage, integrated- circuit instrumentation amplifier designed for signal conditioning requirements where very high performance is desired. A multiamplifier, monolithic design, which uses Burr- Brown’s ultra-low drift, low-noise technology, provides the highest performance with maximum versatility at the lowest cost and makes the INA104 ideal for even high volume applications. Burr-Brown’s compatible thin-film resistors and lasertrimming techniques are used for minimizing offset voltage and temperature drift. This advanced technique also maximizes common-mode rejection and gain accuracy. The INA104 also contains a fourth operational amplifier, specified separately, which can conveniently be used for some important applications such as single capacitor active low-pass filtering, easy output level shifting, common-mode voltage active guard drive, and increased gain (x 10,000 and greater).
