XE8805/05A Sensing Machine
Data Acquisition MCU
with Zooming ADC and DACs
XE8805/05A – SX8805R Sensing
Machine Data Acquisition with 16+10 bit
ZoomingADC™ and buffered DACs
General Description
The XE8805A is a data acquisition ultra low-
power low-voltage system on a chip (SoC) with a
high efficiency microcontroller unit embedded
(MCU), allowing for 1 MIPS at 300uA and 2.4 V,
and multiplying in one clock cycle.
The XE8805A includes a high resolution
acquisition path with the 16+10 bits ZoomingADC
and two buffered DACs.
The XE8805A is available with on chip ROM (the
SX8805) or Multiple-Time-Programmable (MTP)
program memory.
Applications
Portable, battery operated instruments
Current loop powered instruments
Wheatstone bridge interfaces
Pressure and chemical sensors
HVAC control
Metering
Sports watches, wrist instruments
