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.
The MAX1358B has dual 10:1 differential input multiplex-
ers (muxes) that accept signal levels from 0 to AV
on-chip 1x to 8x programmable-gain amplifier (PGA)
allows measuring low-level signals and reduces external
circuitry required.
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.
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 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.
