9.1 Application Information

The ADS1278-SP is a radiation-hardened high resolution delta-sigma ADC that is ideal for precision sensing and high accuracy instrumentation applications. With eight simultaneous sampling 24-bit ADCs integrated, the device reduces the board area needed to digitize eight analog signals.
