Analog Microelectronics AM417
AM417 is a low-cost ratiometric interface IC which has been specifically designed for the conditioning of differential signals. The IC is particularly suitable for the signal evaluation of sensor elements which have to be powered by an internal current source (OP). These include piezoresistive and magnetoresistive silicon measuring cells and temperature sensing elements based on a resistor setup.| Part No. | AM417 |
