PRODUCTION DATA.
The P Gain is designed with precision, low drift, low flicker noise, chopper-stabilized amplifiers. The P Gain is implemented as an Instrument Amplifier as shown in Figure 11.
The gain of this stage is adjustable using 3 bits in P_GAIN_SELECT register to accommodate sense elements with wide-range of signal spans.
The P Gain amplifier can be configured to measure half-bridge output. In this case, the half bridge can be connected to either VINPP or VINPN pins, while the other pin is internally connected to VBRG/2.
