63. How to Stay Out of Deep Water When Designing with Bridge Sensors
    Gustavo Castro Scott Hunt
    Analogue Design Measurement Analog Devices AD5601 AD7091 AD8237 AD8420 AD8505
    Analog Dialogue Instrumentation amplifiers (in-amps) can condition the electrical signals generated by sensors, allowing them to be digitized, stored, or used to control processes. The signal is typically small, so the amplifier may need to be ...
