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.
