Once programmed through its I2C interface, the device can operate independently, periodically waking itself to scan all four ADC channels while using only 5 uW. This frees the MCU to process other activities or power down entirely to yield significant power savings in energy harvesting, medical, communications, remote sensor signal monitoring, and portable applications.
Key features and benefits of the ADS7924
· The ADS7924 uses only 5 uW of power when programmed to scan all four channels every 10 ms for the lowest power consumption of any quad channel 12-bit ADC.
· For applications requiring additional signal conditioning, the device can share one operational amplifier for all four channels. The ADS7924 can wake up and shut down the op amp to synchronize with the sampling and conversion timing of the ADS7924 for additional power savings.
· Maximize the ADS7924’s performance for energy harvesting and portable medical, communications, and remote sensor signal monitoring applications using TI’s ultra-low power MSP430™ MCU platform.
