16-Bit Data-Acquisition Systems with ADC, DACs, UPIOs, RTC, Voltage Monitors, and Temp Sensor
General Description
The MAX1358/MAX1359/MAX1360 smart data-acquisition
systems (DAS) are each based on a 16-bit, sigma-delta
analog-to-digital converter (ADC) and system-support
functionality for a microprocessor (μP)-based system.
These devices integrate an ADC, DACs, operational
amplifiers, internal 1.25V/2.048V/2.5V selectable 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 MAX1358/MAX1359/MAX1360 have 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 MAX1358/MAX1359/MAX1360 operate from a single
+1.8V to +3.6V supply and consume only 1.4mA in
normal mode and only 6.1μA in sleep mode.
The MAX1358 has two DACs with one uncommitted op
amp; the MAX1359 has one DAC with two uncommitted
op amps; and the MAX1360 has three uncommitted
op amps.
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 MAX1358/MAX1359/MAX1360 are available in a
space-saving 40-pin TQFN package and are specified
over the commercial (0°C to +70°C) and the extended
(-40°C to +85°C) temperature ranges.
