The PGA900 is a signal conditioner for resistive sensing applications. It can accommodate various sensing element types. The PGA900 conditions its input signals by amplification and digitization through two analog front end channels. With the user programmed software in the on-chip ARM Cortex M0 processor, the PGA900 can perform linearization, temperature compensation, and other user defined compensation algorithms. The conditioned signal can be output as ratiometric voltage, absolute voltage, 4- to 20-mA current loop or PWM. The data and configuration registers can also be accessed through SPI, I2C, UART, and two GPIO ports. In addition, the unique OWI allows communication and configuration through the power supply pin without using additional lines. The PGA900 operating voltage is from 3.3 V to 30 V and it can operate in temperatures from –40°C to +150°C.
