TM 2 I2C-ADC I C 12-Bit, 8-CH ANALOG-TO-DIGITAL CONVERTER User Manual GRAVITECH.US uResearch GRAVITECH GROUP Copyright 2007 MicroResearch GRAVITECH GROUP WWW.GRAVITECH.US TM 2 I2C-ADC I C 12-Bit, 8-CH ANALOG-TO-DIGITAL CONVERTER User Manual Description Features The I2C-ADC board is a 14-pin CMOS Stand alone module, no external device that provides 8-CH, 12-bit of components required 2 Analog to Digital Converter (ADC) using On-board IC address jumpers, 2 IC bus. There are no external pull-up resistors, power LED and components required. Only two signal 2.5V reference lines SDA and SCL plus supply voltage Decoupling supply voltage and ground are required to be connected. Design easy for breadboard This makes it perfect for embedded High quality double sided PCB systems that require analog-to-digital All SMT components converter. Small and compact in size 0.70 x 0.70 inches This board features innovations that set it Dual row 0.6 width, 0.1 pitch apart from other ADC module. Innovations header pins 2 feature like on-board I C address jumpers, Operating power supply voltage pull-up resistors, power LED and 2.5V range of 2.7V to 5V reference. The module can be quickly Suitable for 3.3V or 5.0V connected directly on to the breadboard. microcontroller The board is small and compact in size 8-Channel multiplexer 0.70 x 0.70 inches. 50kHz sampling rate Internal 2.5V reference The I2C-ADC is designed base on 2 I C interface supports: Standard, ADS7828 IC. It is a single-supply, low- Fast and High-Speed Modes power, 12-bit data acquisition device that 2 features a serial I C interface and an 8- channel multiplexer. The Analog-to-Digital Applications (A/D) converter features a sample-and- hold amplifier and internal, asynchronous 2 clock. The combination of an I C serial, 2- Voltage-supply monitoring wire interface and micropower Isolated data acquisition consumption makes the I2C-ADC ideal for applications requiring Transducer interfaces the A/D converter to be close to the input Battery-operated systems source in remote locations and for Remote data acquisition applications requiring isolation. And much more 2 Two jumper pins vary the fixed I C address and allow up to four devices to 2 share the same I C bus. That is total of 32 channels. 2 * I C is a trademark of Philips Semiconductors Corporation. Copyright 2007 MicroResearch GRAVITECH GROUP WWW.GRAVITECH.US
