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. An
on-chip 1x to 8x programmable-gain amplifier (PGA)
allows measuring low-level signals and reduces external circuitry required.
