The AD7328BRUZ is a 8-channel Software-selectable True Bipolar Input 12-bit Plus Sign 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 analogue ICs capable of 33V operation in a footprint that no previous generation of high voltage parts could achieve. Unlike analogue ICs using conventional CMOS processes, iCMOS components can accept bipolar input signals while providing increased performance, dramatically reduced power consumption and reduced package size. It can accept true bipolar analogue input signals. The successive approximation ADC has four software-selectable input ranges: ±10, ±5, ±2.V and 0 to +10V. Each analogue input channel can be independently programmed to one of the four input ranges.

The ADS1015IDGST is a Precision Analogue-to-digital Converter (ADC) with 12 bits of resolution. Designed with precision, power and ease of implementation in mind. It features an onboard reference and oscillator. Data are transferred via an I²C-compatible serial interface, four I²C slave addresses can be selected. It operates from a single power supply ranging from 2.0 to 5.5V. It can perform conversions at rates up to 3300 samples per second (SPS). An onboard PGA is available, that offers input ranges from the supply to as low as ±256mV, allowing both large and small signals to be measured with high resolution. Also features an input multiplexer (MUX) that provides two differential or four single-ended inputs. It operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion and greatly reduces current consumption during idle periods.

• Internal low-drift voltage reference
• Internal oscillator
• Internal PGA
• I²C Interface, pin-selectable addresses
