MMR920

MinebeaMitsumi piezoresistive pressure sensors use MEMS technology. They feature a high-resolution Σ-Δ (Sigma-Delta) ADC, providing highly accurate digital pressure readings. The MMR920 series is a gauge pressure sensor module that includes a MEMS gauge pressure sensor with a dedicated analog front-end IC to provide a fully calibrated and temperature-compensated digital output via I²C or SPI interface. The specially developed MEMS diaphragm features high sensitivity and low noise, making it ideal for accurate measurements in low-pressure ranges. Its unique packaging design, which isolates the electronics from the high-pressure port, ensures excellent robustness. A built-in digital filter further reduces noise, with a configurable cutoff frequency to match specific application requirements. The sensor requires no complex drive or control circuitry—high-performance systems can be easily built using this module and a host microcontroller.
