Analog Devices Inc. LT5401 Matched Resistor Network
Analog Devices LT5401 Matched Resistor Network is optimized for use with fully differential or difference amplifiers. The Matched Resistor Network offers 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.
The LT5401 Matched Resistor Network can be used to configure differential or difference gain by matching ratio, ensuring high CMRR, low gain errors, and low gain drift to levels far too difficult to achieve with discrete passive components. This high level of precision reduces calibration requirements in many applications and offers 10 times higher performance than a ±0.01% discrete solution.
The LT5401 is available in a compact 10-lead MSOP package with an exposed paddle. This is for improved thermal performance over a temperature range of –55°C to 150°C.
