Description

The LT®5401 is an ultra-precision matched resistor network optimized for use with fully differential or differential amplifiers, providing excellent matching specifications over the entire temperature range. The LT5401 contains two strings of matched resistors, each providing three tap points. The resulting matching ratios are ideally suited for precisely setting the gain or attenuation of differential amplifiers. When used to configure differential or differential gain, the LT5401's excellent ratio matching ensures high CMRR, low gain error, and low gain drift to levels difficult to achieve with discrete passive components. This high accuracy reduces calibration requirements in many applications, and its performance is 10 times better than ±0.01% discrete solutions. The LT5401 is available in a compact 10-lead MSOP package with an exposed pad for improved thermal performance over a temperature range of –55°C to 150°C.

Features

   1. Excellent Matching Performance:

       - Resistor ratio matching accuracy: Extremely low typical values (e.g., 0.025%), ensuring very high consistency between multiple resistors.

       - Low temperature coefficient matching: Typical values as low as 3 ppm/°C, meaning that the changes in resistance values are almost synchronous with temperature changes, and the ratio remains stable.

   2. High Absolute Accuracy:

       - The absolute tolerance of each resistor is typically 0.5%.

   3. Structural Advantages:

       - Monolithic structure: All resistors are integrated on the same silicon die and manufactured simultaneously using the same process, providing better matching and temperature tracking characteristics than discrete resistors.

   4. Application Optimization:

       - Ideal for building precision voltage dividers, gain setting networks (such as instrumentation amplifiers), gain amplifiers, gain boosters, and circuits requiring high common-mode gain rejection.

Model Suffix Explanation

   1. LT5401: Base model, representing this series of resistor networks.

       - I: Indicates industrial-grade operating temperature range (typically -40°C to +85°C).

       - MSE: Indicates the package type is MSOP-10 (10-pin miniature small outline package).

   4. #PBF: Indicates that the device complies with lead-free (Pb-Free) environmental standards.

Typical Application Scenarios

   1. Precision data acquisition systems 

   2. Electronic scales and sensor interfaces

   3. Medical instruments

   4. Automatic test equipment (ATE)

   5. Any voltage divider or ratio measurement circuit requiring long-term stability and accuracy
