DataSheet.in 19-3710; Rev 2; 8/10 16-Bit, Data-Acquisition System with ADC, DAC, UPIOs, RTC, Voltage Monitors, and Temp Sensor 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. An on-chip 1x to 8x programmable-gain amplifier (PGA) measures low-level signals and reduces external circuitry required. The MAX1359B operates from a single +1.8V to +3.6V supply and consumes only 1.4mA in normal mode and only 6.1µA in sleep mode. The serial interface is compatible with either SPI™/QSPI™ or MICROWIRE™, and is used to power up, configure, and check the status of all functional blocks. The MAX1359B is available in a space-saving 40-pin TQFN package and is specified over the commercial (0°C to +70°C) and the extended (-40°C to +85°C) temperature ranges.
