DESCRIPTION

The SX8725S is a data acquisition system based on Semtechs low power ZoomingADC? technology. It directly connects most types of miniature sensors with a general purpose microcontroller.

With 1 differential input, it can adapt to multiple sensor systems. Its digital outputs are used to bias or reset the sensing elements.

FEATURES

■ Up to 16-bit differential data acquisition

■ Programmable gain: (1/12 to 1000)

■ Sensor offset compensation up to 15 times full scale of input signal

■ 1 differential or 2 single-ended signal inputs

■ Programmable Resolution versus Speed versus Supply current

■ Digital outputs to bias Sensors

■ Internal or external voltage reference

■ Internal time base

■ Low-power (250 uA for 16b @ 250 S/s)

■ SPI interface, 2 Mbps serial clock

APPLICATIONS

■ Industrial pressure sensing

■ Industrial temperature sensing

■ Industrial chemical sensing

■ Barometer

■ Compass
