AM417

The AM417 is a low cost ratiometrical voltage transmitter, designed for flexible bridge input signal conditioning. The IC contains a ratiometric current source for transducer excitation, a high accuracy instrumentation amplifier for differential input signals, and a voltage output driver. Gain, offset, and output voltage range are adjustable by external resistors. The voltage output stage is designed as an open collector stage. The output current is +10mA. A simple current limitation is possible by adding an external resistor. With its functional blocks and possibilities to adjust all important parameters for sensor calibration, the small package dimensions (SO8), and the low costs the AM417 is ideally suited for automotive sensor interface applications.
