New low- and high-side bidirectional, zero-drift, current sense amplifiers

Based on a zero-drift architecture that delivers high performance for precision current sensing, the TSC21x series brings excellent accuracy and robustness to your design.

With a wide supply voltage range from 2.7 to 26 V, TSC21 current sense amplifiers support temperatures from -40 to 125 °C, making them ideal for industrial and automotive applications. Automotive Grade (AG) versions are available.

TSC21 current sense amplifiers are available with six different voltage gain (V/V) options.

Gain Setting
200 V/V

Key features and benefits

  • High precision: Very low offset voltage
  • Great accuracy: Accuracy virtually unaffected by temperature change
  • Robustness: High ESD tolerance guaranteed
