The MAXQ7670 from Maxim Integrated Products, Sunnyvale, CA, is an automotive microcontroller for low-amplitude signals, designed to measure signals in the microvolt range from sensors with differential outputs, such as AMR sensors. The device integrates all functions needed to measure the low-amplitude signals from multiple AMR sensors without external amplification and can calculate angle displacements in real time and output the results on a CAN network. Features include 8 single-ended/4 differential inputs; a programmable gain amplifier; 250 Ksps ADC with 10-bit resolution; a 16-bit RISC microcontroller core; CAN, SPI, and JTAG interfaces; and 7 general-purpose I/O.
