19-5027; Rev 0; 12/09 16-Bit Data-Acquisition System with ADC, DAC, UPIOs, RTC, Voltage Monitors, and Temp Sensor General Description The MAX11358B smart data-acquisition system (DAS) is based on a 16-bit, sigma-delta analog-to-digital converter (ADC) and system-support functionality for a microprocessor (µP)-based system. These devices integrate an ADC, DACs, operational amplifiers, internal selectable-voltage reference, temperature sensors, analog switches, a 32kHz oscillator, a real-time clock (RTC) with alarm, a high-frequency-locked loop (FLL) clock, four user-programmable I/Os, an interrupt generator, and 1.8V and 2.7V voltage monitors in a single chip. The MAX11358B has dual 10:1 differential input multiplexers (muxes) that accept signal levels from 0 to AVDD.
