Gravitech . I2C-DAC

The I2C-DAC board is a 6-pin CMOS 8-bit digital-to-analog converter device using I2C bus. There are no external components required. Only two signal lines SDA and SCL plus supply voltage and ground are required to be connected. This makes it perfect for embedded systems that require digital-to-analog converter. This board features innovations that set it apart from other digital-to-analog converter module. Innovations feature like on-board I2C address jumpers, pull-up resistors, and power LED. The module can be quickly connected directly on to the breadboard. The board is small and compact in size 0.70 x 0.47 inches. The I2C-DAC is designed base on DAC5571 IC. It is a low-power, single-channel, 8-bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The output voltage range of the DAC is 0V to VCC. The I2C-DAC incorporates a power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid write to the device takes place. A jumper pins vary the fixed I2C address and allow up to two devices to share the same I2C bus.Features: bull; Up to 2 devices on the same bus bull; Resolution: 8-bit bull; Fast Update Rate: 188 KSPS bull; I2C Interface up to 3.4 Mbps bull; On-Chip Output Buffer Amplifier, Rail-to-Rail Operation bull; Stand alone module, no external components required bull; On-board I2C address jumpers, pull-up resistors and power LED bull; Decoupling supply voltage bull; Design easy for breadboard bull; High quality double sided PCB bull; All SMT components bull; Small and compact in size 0.70 x 0.47 inches bull; Dual row 0.6@ width, 0.1@ pitch header pins bull; Flexible operating power supply voltage range of 2.7V to 5.5V bull; Suitable for 3.3V or 5.0V microcontroller For more information please see: I2C-DAC User Manual Basic Stamp BS2P example code: I2C-DAC.bsp PICAXE example code: I2C-DAC-PICAXE.bas Arduino
