® INA104 Very-High Accuracy INSTRUMENTATION AMPLIFIER FEATURES q VERSATILE FOUR OP AMP DESIGN q ULTRA-LOW VOLTAGE DRIFT: 0.25µV/°C, max q LOW OFFSET VOLTAGE: 25µV, max q LOW NONLINEARITY: 0.002%, max q LOW NOISE: 13nV/√ Hz at f0 = 1kHz q HIGH CMR: 106dB at 60Hz, min q HIGH INPUT IMPEDANCE: 1010Ω q LOW COST DESCRIPTION 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 BurrBrown’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).
