com 12-/16-Bit DASs with ADC, DACs, DPIOs, APIOs, Reference, Voltage Monitors, and Temp Sensor General Description The MAX1329/MAX1330 are smart data acquisition systems (DASs) based on a successive approximation register (SAR) analog-to-digital converter (ADC).
These devices are highly integrated, offering an ADC, digitalto-analog converters (DACs), operational amplifiers (op amps), voltage reference, temperature sensors, and analog switches in the same device.
The MAX1329/MAX1330 offer a single ADC with a reference buffer.
The ADC is capable of operating in one of two user-programmable modes.
In normal mode, the ADC provides up to 12 bits of resolution at 312ksps.
In DSP mode, the ADC provides up to 16 bits of resolution at 1000sps.
The ADC accepts one external differential input or two external single-ended inputs as well as inputs from other circuitry on-board.
An on-chip programmable gain amplifier (PGA) follows the analog inputs, reducing external circuitry requirements.
The PGA gain is adjustable from 1V/V to 8V/V.
The MAX1329/MAX1330 operate from a 1.
8V to 3.
6V digital power supply.
Shutdown and sleep modes are available for power-saving applications.
Under normal operation, an internal charge pump boosts the supply voltage for the analog circuitry when the supply is < 2.
7V.
The MAX1329/MAX1330 offer four analog programmable I/Os (APIOs) and four digital programmable I/Os (DPIOs).
The APIOs can be configured as general-purpose logic inputs and outputs, as a wake-up function, or as a buffer and level shifter for the serial interface to communicate with slave devices powered by the analog supply, AVDD.
The DPIOs can be configured as generalpurpose logic inputs and outputs as well as inputs to directly control the ADC conversion rate, the analog switches, the loading of the DACs, wake-up, sleep, and shutdown modes, and as an interrupt for when the analog-to-digital conversion is complete.
The MAX1329 includes dual 12-bit ...
