The PGA900is a signal conditioner for resistive sensing applications. It can accommodate various sensingelement types. The PGA900conditions its input signals by amplification and digitization through two analog front endchannels. With the user programmed software in the on-chip ARM Cortex M0 processor, thePGA900can perform linearization, temperature compensation, and other user defined compensationalgorithms. The conditioned signal can be output as ratiometric voltage, absolute voltage, 4- to20-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 allowscommunication and configuration through the power supply pin without using additional lines. ThePGA900operating voltage is from 3.3 V to 30 V and it can operate in temperatures from –40°C to+150°C.
