Product Details
●The AD7324 is a 4-channel, 12-bit plus sign, successive approximation ADC designed on the _i_CMOS (industrial CMOS) process. _i_CMOS is a process combining high voltage silicon with submicron CMOS and complementary bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no previous generation of high voltage parts could achieve. Unlike analog ICs using conventional CMOS processes, _i_CMOS components can accept bipolar input signals while providing increased performance, dramatically reduced power consumption, and reduced package size.
●The AD7324 can accept true bipolar analog input signals. The AD7324 has four software-selectable input ranges: ±10 V, ±5 V, ±2.5 V, and 0 V to +10 V. Each analog input channel can be independently programmed to one of the four input ranges. The analog input channels on the AD7324 can be programmed to be single-ended, true differential, or pseudo differential.
●The ADC contains a 2.5 V internal reference. The AD7324 also allows for external reference operation. If a 3 V reference is applied to the REFIN/OUT pin, the AD7324 can accept a true bipolar ±12 V analog input. Minimum ±12 V VDD and VSS supplies are required for the ±12 V input range. The ADC has a high speed serial interface that can operate at throughput rates up to 1 MSPS.
