The AD7329 is a 1 MSPS, 8-channel, software-selectable, true bipolar input, 12-bit plus sign ADC. It features true bipolar input ranges, software-selectable input ranges, a throughput rate of 1 MSPS, 8 analog input channels, single-ended true differential and pseudo differential analog input capability, and more.
The AD7329 is an 8-channel, 1 MSPS successive approximation ADC designed on iCMOS process technology. It features a 12-bit plus sign resolution capable of accepting true bipolar analog input signals across four software-selectable ranges: +10 V, +5 V, +2.5 V, and 0 V to +10 V.
The device supports single-ended, true differential, and pseudo differential analog input capabilities. It includes an internal 2.5 V reference but allows for external reference operation up to 3 V. The ADC operates with a high-speed serial interface compatible with SPI/QSPI/DSP/MICROWIRE protocols.
