SBOU024C august 2004 – july 2023 PGA309
BV: Bridge Nonlinearity with Applied Pressure. Maximum error at mid-scale input range given as a decimal equivalent of % of full-scale range (%FSR). For Example, %FS: +2.5% FS = 0.025, −2.5% = −0.025.
FSS: Full-Scale Bridge Sensitivity for Sensor at PMAX (5 mV/V)
GL: Total PGA309 Gain of VOUT/VIN when using the Linearization Circuit.
GT: Total PGA309 Gain of VOUT/VIN.
GT = (Front-End PGA Gain)(Gain DAC)(Output Amplifier Gain).
KEXC: PGA Excitation Coefficient. Scale factor on VREF.
KLIN: PGA309 Linearization Coefficient
KP: Pressure Constant. Converts linear input pressure to nonlinear pressure detected by sensor. Referenced to full-scale input pressure.
P: Pressure Input to Sensor
PMIN: Minimum Sensor Input Pressure
PMAX: Maximum Sensor Input Pressure
PNL: Nonlinear Pressure Output of Bridge with Linear Pressure Input P
VEXC: Bridge Voltage Excitation (generated by PGA309 based on VREF, KLIN, KEXC, VOUT)
VOUT MIN: Minimum PGA309 VOUT Voltage for PMIN Bridge Sensor Input
VOUT MAX: Maximum PGA309 VOUT Voltage for PMAX Bridge Sensor Input
VREF: PGA309 Reference Voltage
