Maxim Integrated Products offers the MAXQ7670A which pushes mixed-signal performance to the 12bit level with a 125Msps ADC, enabling measurements in the microvolt range from various types of sensors like anisotropic magnetoresistive (AMR) sensors.

MAXQ7670A, the addition to the line of MAXQ mixed-signal microcontrollers is a system-on-chip (SoC) mixed-signal microcontroller that integrates all the functions needed to accurately measure small-amplitude differential analogue input signals.


Designed to digitise and process signals in harsh, space-constrained environments, this SoC is well-suited for automotive applications such as steering, braking, and throttle-position control, as well as industrial control applications such as valve positioning and shaft rotation. The on-chip RISC CPU and embedded CAN 2.0B bus controller allow real-time data processing for smart sensor networks. It has SPI interface, JTAG interface and seven general-purpose I/Os.

It packs a 16bit RISC MAXQ microcontroller core. It has a 2KB of SRAM for data and 64KB of automotive-grade flash memory. It is specified over the -40�C to +125�C automotive temperature range

It is available now in a 5x5mm, 40-pin TQFN package and pricing starts at $3.58 (1000-up, FOB USA). An evaluation kit is available to speed designs.
