3 Description

The AFE11612-SEP is a highly integrated analog

monitor and control device designed for high-density,

general-purpose monitor and control systems. The

device includes 12 12-bit digital-to-analog converters

(DACs) and a 16-channel, 12-bit, analog-to-digital

converter (ADC). The device also incorporates

eight general-purpose inputs and outputs (GPIOs),

two remote temperature sensor channels, and a local

temperature sensor channel.

The device has an internal 2.5-V reference that

sets the DAC to an output voltage range of

0 V to 5 V. The device also supports operation

from an external reference. The device supports

communication through both SPI-compatible and I2Ccompatible

interfaces.

The device high level of integration significantly

reduces component count and simplifies closed-loop

system design, thus making the device a great choice

for high-density applications where radiation-tolerance

and board space are critical.
