MM3609ARRE

MM3609ARRE is a MinebeaMitsumi analog front-end IC in a PLP-24A package — a sensor AFE with two resistive-bridge input channels and a 24-bit delta-sigma ADC, for pressure, load and strain sensing in industrial and automotive modules. It interfaces over high-speed I2C (3.4 Mbps) or SPI (5 Mbps), runs from a 1.71 V to 3.6 V supply and operates from -40 °C to +85 °C; the formal datasheet is Ver. 1.0 and the code appears on the manufacturer's official parts list. Selection advice: take the package designation from the datasheet outline — PLP-24A, 3.0 mm body at 0.4 mm pitch — since the product page abbreviates it as PLP-24, and confirm the land pattern against the datasheet drawing before layout. As a bridge AFE, system accuracy is set as much by excitation stability, input filtering and layout around the sensor inputs as by the ADC headline resolution; prototype the complete signal chain with your actual bridge sensor before freezing gain and data-rate settings. Parameters verified against MinebeaMitsumi documentation.
