LT5401AIMSE#PBF

LT5401AIMSE#PBF is a matched resistor network for precision amplifiers. It is an ultra-precision matched resistor network optimized for use with fully differential or difference amplifiers, and with excellent matching specifications over the entire temperature range. The LT5401 contains two strings of matched resistors, each providing three tap points. The resulting matched ratios are well suited for precisely setting a differential amplifier’s gain or attenuation. When used to configure differential or difference gain, the LT5401’s excellent ratio matching ensures high CMRR, low gain errors and low gain drift to levels far too difficult to achieve with discrete passive components. Typical applications include fully differential amplifiers, difference amplifiers, reference dividers, precision summing/subtracting.
