Microcontroller with 12-Bit ADC, PGA, 64KB Flash, and CAN Interface
General Description
The MAXQ7670A is a highly integrated solution for measuring multiple analog signals and outputting the results on a control area network (CAN) bus. The device operates from a single 5V supply and incorporates a highperformance, 16-bit reduced instruction set computing (RISC) core, a SAR ADC, and a CAN 2.0B controller, supporting transfer rates up to 1Mbps. The 12-bit SAR ADC includes an amplifier with programmable gains of 1V/V or 16V/V, 8 input channels, and conversion rates up to 125ksps. The eight single-ended ADC inputs can be configured as four unipolar or bipolar, fully differential inputs. For single-supply operation, the external 5V supply powers the digital I/Os and two separate integrated linear regulators that supply the 2.5V digital core and the 3.3V analog circuitry. Each supply rail has a dedicated power-supply supervisor that provides brownout detection and power
