16-Bit, Data-Acquisition System with ADC, DACs,  
UPIOs, RTC, Voltage Monitors, and Temp Sensor  
MAX1358B  
General Description  
Features  
o +1.8V to +3.6V Single-Supply Operation  
The MAX1358B smart data-acquisition system (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. This device integrates  
an ADC, DACs, operational amplifiers, internal selec-  
table-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.  
o Multichannel, 16-Bit, Sigma-Delta ADC  
10sps to 477sps 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 and SPST Analog Switches  
The MAX1358B has dual 10:1 differential input multiplex-  
ers (muxes) that accept signal levels from 0 to AV . An  
DD  
on-chip 1x to 8x programmable-gain amplifier (PGA)  
allows measuring low-level signals and reduces external  
circuitry required.  
o Selectable References  
1.25V, 2.048V, and 2.5V  
o Internal Charge Pump  
o System Support  
RTC and Alarm Register  
Internal/External Temperature Sensor  
Internal Oscillator with Clock Output  
User-Programmable I/O and Interrupt Generator  
The MAX1358B operates from a single +1.8V to +3.6V  
supply and consumes only 1.15mA in normal mode and  
only 3µA in sleep mode. The MAX1358B has two DACs  
with one uncommitted op amp.

Monitors  
o SPI/QSPI/MICROWIRE, 4-Wire Serial Interface  
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.  
o Space-Saving (6mm x 6mm x 0.8mm), 40-Pin  
TQFN Package  
Ordering Information  
The MAX1358B 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) tem-  
perature ranges.
