ILPS22QSTR

ILPS22QSTR Description

The ILPS22QSTR from STMicroelectronics is a high-precision absolute pressure sensor designed for demanding industrial applications. It operates within a 1.7V to 3.6V supply range and delivers 24-bit digital output via I2C, I3C, or SPI interfaces, ensuring compatibility with modern embedded systems. With an operating pressure range of 3.77PSI to 58.89PSI (26kPa to 406kPa) and a maximum pressure tolerance of 290.08PSI (2000kPa), it excels in environments requiring robust performance. The sensor achieves an exceptional accuracy of ±0.01PSI (0.05kPa), making it ideal for precision-critical tasks. Packaged in a 10-pin HLGA form factor with SMD (SMT) tab termination, it is optimized for surface-mount assembly and supplied in Tape & Reel (TR) for automated production.
