    RTKA-BDGSTKEV2Z 2. Design Considerations Design Considerations ISL28134 The ISL28134 is an ideal choice for the input amplifier for a strain gauge design. The ISL28134 uses auto-correction circuitry to provide ultra low offset voltage (2.5μV) and low offset temperature drift (15nV/°C). The very low 1/f noise corner (<0.1Hz) and low input noise voltage (8nV/√Hz at 100Hz) of the amplifier makes the...
