A 2-channel successive approximation ADC converts bipolar and unipolar analog input ranges at up to 1 MSPS. The converter provides 12-bit plus sign resolution with software-selectable input ranges including ±10 V, ±5 V, ±2.5 V, and 0 V to 10 V. A high speed serial interface supports SPI, QSPI, MICROWIRE, and DSP-compatible operation. The device operates with a 2.7 V to 5.25 V logic supply and supports external reference operation for precision data acquisition systems.
