SLDS204B October 2014 – June 2020 PGA300
PRODUCTION DATA.
The bridge sensor voltage-supply block of the PGA300 provides power to the resistive-bridge sensor. The bridge sensor supply in the PGA300 is configurable to a nominal output voltage of 2.5-V, 2-V, or 1.25-V using the VBRDG_CTRL[1:0] bits in the BRDG_CTRL register to accommodate bridge sense elements with different resistor values. The bridge sensor supply is ratiometric to the accurate reference, as illustrated in Figure 2.
