Ssis351 2021

While earlier models required hardware jumpers to switch between analog and digital outputs, the SSIS351 2021 allows firmware configuration via a single-wire interface. Engineers can now toggle between 0–10V analog, 4–20 mA current loop, and I²C modes without opening the enclosure.

For engineers planning to adopt this sensor, here is a quick integration checklist:

To understand its market position, we must compare the SSIS351 2021 with two alternatives: the MPXHZ6250AC6T1 (NXP) and the BMP581 (Bosch). ssis351 2021

| Feature | SSIS351 2021 | NXP MPXHZ6250 | Bosch BMP581 | |---------|--------------|---------------|--------------| | Primary measurement | Pressure + temp | Absolute pressure | Barometric pressure | | Output | Analog + I²C/SPI | Analog only | I²C/SPI | | Max pressure range | 0–350 kPa | 20–250 kPa | 30–125 kPa | | Cost (1000-unit) | $4.50 | $7.20 | $3.90 | | Supply chain lead time | 12 weeks | 24 weeks | 8 weeks |

The SSIS351 2021 strikes a balance between NXP’s ruggedness and Bosch’s low cost, making it the preferred choice for mid-volume industrial designs where analog and digital flexibility is required. While earlier models required hardware jumpers to switch
