GZP170-701A from Sencoch Semiconductor, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No connection. Leave floating.
2	+sig	output	Positive bridge output (+Sig). One differential output of the Wheatstone bridge; produces a small mV-level signal proportional to applied pressure. Full-scale output 60-120 mV at 700 kPa with 5 V bridge excitation.
3	NC	unconnected	No connection. Leave floating.
4	GND	power_in	Ground / bridge low-side return. Bridge arm resistance 4-6 kΩ (typ 5 kΩ) between Vexc and GND.
5	NC	unconnected	No connection. Leave floating.
6	-sig	output	Negative bridge output (-Sig). Complementary differential output of the Wheatstone bridge. Zero-point output between +sig and -sig is ±30 mV max at reference conditions.
7	NC	unconnected	No connection. Leave floating.
8	Vexc	power_in	Bridge excitation input. Constant-voltage supply ≤15 V DC (typ 5 V) or constant-current drive ≤3.0 mA (typ 1 mA). Drives the piezoresistive Wheatstone bridge.
