HBGK's GPS/GBS/GNS system is unique: one MEMS chip supports 3 pressure modes through package configuration. GPS (Gauge Positive): standard positive range (e.g. 0~1bar). GBS (Gauge Bidirectional): bidirectional range (e.g. -0.5~0.5bar). GNS (Gauge Negative): negative range (e.g. -1~0bar). Benefits: 1) One chip qualification for 3 use cases (~60% certification savings); 2) Unified BOM simplifies inventory; 3) Consistent performance across all variants. Available in both Analog and Digital I2C across HBP1101/1201/1301/1302/1311/1312/1801/1901 series.
