Description

12BIT ADC 8CH 1MSPS SMD TSSOP24

The AD73291 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 CMOS and low voltage CMOS. 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 AD7329 can accept true bipolar analog input signals. The AD7329 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 AD7329 can be programmed to be single-ended, true differential, or pseudo differential. The ADC contains a 2.5 V internal reference. The AD7329 also allows for external reference operation. If a 3 V reference is applied to the REFIN/REFOUT pin, the AD7329 can accept a true bipolar ±12 V analog input. The ADC has a high speed serial interface that can operate at throughput rates up to 1 MSPS.
