MAX1359B Datasheet Data-acquisition System

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: DataSheet.in 19-3710; Rev 2; 8/10 16-Bit, Data-Acquisition System with ADC, DAC, UPIOs, RTC, Voltage Monitors, and Temp.

General Description

The MAX1359B smart data-acquisition systems (DAS) is based on a 16-bit, sigma-delta analog-to-digital converter (ADC) and system-support functionality for a microprocessor (µP)-based system.

This device integrates an ADC, DAC, two operational amplifiers, internal 1.25V/2.048V/2.5V selectable reference, temperature sensors, analog switches, a 32kHz oscillator, a realtime 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 MAX1359B has dual 10:1 differential input multiplexers (muxes) that accept signal levels from 0 to AVDD.
