MAX11358B
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 32k Hz 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. The MAX11358B operates from a single +1.8V to +3.6V supply and consumes only 1.15m A in normal mode and only 3µA in sleep mode. The MAX11358B has two DACs with one unmitted op amp. The serial interface is patible...
