DESCRIPTION
The SX8725C 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)
■ Fast I2C interface with external address option, no clock stretching required
APPLICATIONS
■ Industrial pressure sensing
■ Industrial temperature sensing
■ Industrial chemical sensing
■ Barometer
■ Compass
