NPX-SPI Datasheet, PDF (1/4 Pages) Amphenol Corporation – 8-bit calibrated output

NPX-SPI
The NPX-SPI uses NovaSensor’s NPX series as
the foundation for a small, digitally compensated
pressure sensor that does not require additional
firmware or software development tools. These
sensors are available in 450, 700 and 1400 kPaA
pressure ranges and provide a 8-bit output
that is scaled to the input pressure. In addition
to pressure, the NPX-SPI will also provide 4
additional data bytes that include temperature,
battery voltage, status and parity error. The NPX-
SPI is meant for low-power operations and will
work with power supplies from 2.1 to 3.6 volts.
Communications with the NPX-SPI is very similar to
that of a serial A/D converter with a CS (chip select)
line, an SDO (data) line, an SCK (clock) line, an ACK
(acknowledging) line and a MODE line. The MODE
lines allows the NPX-SPI to remain on standby
mode or placed in sleep mode.
