The ADS8255 is a high-performance analog system-on-chip (SoC) device with an 16-bit, 1-MSPS A/D converter, 4-V internal reference, an on-chip ADC driver (OPA), and a 8-channel single ended multiplexer. The channel count of the multiplexer and auto/manual scan modes of the device are user selectable.

The ADC driver is designed to leverage the very high noise performance of the differential ADC at optimum power usage levels.

The ADS8255 outputs a buffered reference signal for level shifting of a ±4-V bipolar signal with an external resistance divider. A Vref/2 output signal is available to set the offset of a signal conditioning circuit. The device also includes an 16-/8-bit parallel interface.

The ADS8255 is available in a 9 mm x 9 mm, 64-pin QFN package and is characterized from -40°C to 85°C.
