Description
The MAX7651/MAX7652 are complete 12-bit data-acquisition systems featuring an algorithmic, switched-capacitor, analog-to-digital converter (ADC), a pulse- width-modulated digital-to-analog converter (DAC), three timer/counters, and an industry-standard 8051 microprocessor core with a variety of I/O peripherals. Power-down capability and full functionality with supply voltages as low as +3V make the MAX7651/MAX7652 suitable for portable and power-sensitive applications.

The MAX7651/MAX7652 perform fully differential voltage measurements with 12-bit resolution, programmable gain, and separate track-and-hold for both positive and negative inputs. The converter accepts versatile input modes consisting of four 2-channel signal pairs or eight 1-channel signals relative to a floating common.

The MAX7651/MAX7652 microprocessor systems feature a CPU, 256 bytes of RAM, two 8kB flash memory, four 8-bit I/O ports, two UARTs, an interrupt controller, and a watchdog timer. Only four clock cycles are required to complete each microprocessor instruction.

The MAX7651/MAX7652 are available in 64-pin TQFP packages.

An evaluation kit is available:  MAX7651EVKIT
