MAX11359A  
16-Bit Data-Acquisition System with ADC, DAC,  
UPIOs, RTC, Voltage Monitors, and Temp Sensor  
General Description  
Features  
o +1.8V to +3.6V Single-Supply Operation  
The MAX11359A smart data-acquisition systems (DAS) is  
based on a 16-bit, sigma-delta analog-to-digital converter  
(ADC) and system-support functionality for a micro-  
processor (µP)-based system. The device integrates an  
ADC, DAC, operational amplifiers, internal selectable-  
voltage reference, temperature sensors, analog switch-  
es, 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.  
o Multichannel 16-Bit Sigma-Delta ADC  
10sps to 512sps Programmable Conversion Rate  
Self and System Offset and Gain Calibration  
PGA with Gains of 1, 2, 4, or 8  
Unipolar and Bipolar Modes  
10-Input Differential Multiplexer  
o 10-Bit Force-Sense DACs  
o Uncommitted Op Amps  
o Dual SPDT Analog Switches  
o Selectable References  
The MAX11359A has dual 10:1 differential input multiplex-  
ers (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.  
1.25V, 1.996V and 2.422V  
o Internal Charge Pump  
o System Support  
Real-Time Clock and Alarm Register  
Internal/External Temperature Sensor  
Internal Oscillator with Clock Output  
User-Programmable I/O and Interrupt Generator  
The MAX11358B 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 MAX11385B has one  
DACs with two uncommitted op amp.

o SPI/QSPI/MICROWIRE, 4-Wire Serial Interface  
o Space-Saving (6mm x 6mm x 0.75mm), 40-Pin TQFN  
The serial interface is compatible with either SPI/QSPI™  
Package  
®
or MICROWIRE , and is used to power up, configure,  
Ordering Information  
and check the status of all functional blocks.
