NSA2862X
Overview
The NSA2862X is a highly integrated sensor conditioner dedicated for Io T applications. It can be used for resistive or voltage output sensors like resistive bridge pressure sensor, thermocouple, RTD etc. The NSA2862X integrates a 24-bit primary signal measurement channel, a 24-bit temperature measurement channel, sensor calibration logic, a pair of constant current sources and a 16-bit DAC. It can provide three kinds digital outputs (I2C, SPI and OWI). The high integrity enables very pact PCB design with very few external ponents. With the internal calibration algorithm built in the MCU, the NSA2862X supports to pensate the temperature drift of zero and span up to the 2nd order and also the linearity up to the 3rd order. The NSA2862X also has a standby mode in which only consumes less 100n A current. It is very suitable for ultra-low power sensor applications
