The AD73271 is an 8-Channel, 12-Bit plus Sign Successive Approximation ADC designed on the iCMOS (industrial CMOS) process. iCMOS 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, iCMOS components can accept bipolar input signals while providing increased performance, dramatically reduced power consumption, and reduced package size.
The AD7327 can accept true bipolar Analog Input signals. The AD7327 has four software selectable inputs Ranges, ±10 V, ±5 V, ±2.5 V and 0 to 10 V. Each analog input channel can be independently programmed to one of the four input ranges. The Analog input channels on the AD7327 can be programmed to be Single-Ended, true Differential or Pseudo Differential.
The ADC contains a 2.5 V Internal reference. The AD7327 also allows for external Reference operation. If a 3 V reference is applied the REFIN/OUT pin the AD7327 can accept a true Bipolar ±12V Analog Input. VDD and VSS supplies of ±12V are required for the ±12 V Input Range. The ADC has a high speed serial interface that can operate at throughput rates up to 500 kSPS.
Product Highlights
- The AD7327 can accept True Bipolar Analog Input signals, ±10 V, ±5 V, ±2.5 V and 0 to 10 V unipolar signals.
- The Eight Analog Inputs can be configured as 8 Single-Ended inputs, 4 True Differential, 4 Pseudo Differential or 7 Pseudo Differential Inputs.
- The ADC has a high speed serial interface that can operate at throughput rates up to 500 kSPS.
- Low power, 18 mW, at a maximum throughput rate of 500 kSPS.
- Channel Sequencer.
