The LT5401 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. 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 exposed paddle for improved thermal performance over a temperature range of –55°C to 150°C.
Applications
- Fully Differential Amplifiers
- Difference Amplifiers
- Reference Dividers
