Analog Devices Inc. AD7327BRUZ-REEL7

Description
The AD7327-EP is an 8-channel, 12-bit plus sign successive approximation ADC designed on the CMOS (industrial CMOS) process. 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 devices achieved. 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-EP can accept true bipolar analog input signals, software-selectable from ±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 AD7327-EP can be programmed to be single-ended, true differential, or pseudo differential.
The ADC contains a 2.5 V internal reference. The AD7327-EP also allows external reference operation. If a 3 V reference is applied to the REFIN/OUT pin, the AD7327-EP can accept a true bipolar ±12 V analog input. Minimum 12 V Von and V 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 500 kSPS.
The AD7327-EP is housed in a 20-lead TSSOP with operation specified from -55°C to 125°C. Additional application and technical information can be found in the AD7327 data sheet.
