SX8722
High gain acquisition for sensor interface
10. Default configuration
The SX8722 default configuration is described in this chapter.
The SX8722 default hardware configuration is as follow:
1uF Vreg capacitor connected to Vreg pin
EE_SDA connected to ground
3.0 - 5.0 power supply on Vbat, 0V on GND
Wheatstone bridge type sensor connected to AC0-AC1 biased through bias pin
VRef = VBias = VBat
Host micro controller I2C connected to SDA and SCL of the SX8722
Host micro controller GPIO connected to RESET input of the SX8722
Figure 22. Schematic of the default configuration
Note:
Startup conditions Reset = ‘0’
10.1. ZoomingADC default settings
The SX8722 starts upon a power on reset and then goes into measurement mode.
By default the measurement mode parameters are as follows:
Differential measurement on channel AC0 - AC1, gain 1, 16 bits resolution, reference on AR1P - AR1N, no filtering,
continuous measurements.
The READY pin will pulse from "0" to "1" at every sample available. The host microcontroller can then read the data.
