There are no external Fast Update Rate: 188 KSPS 2 components required. Only two signal I C Interface up to 3.4 Mbps lines SDA and SCL plus supply voltage On-Chip Output Buffer Amplifier, and ground are required to be connected. Rail-to-Rail Operation This makes it perfect for embedded Stand alone module, no external systems that require digital-to-analog components required 2 converter. On-board IC address jumpers, pull-up resistors and power LED This board features innovations that set it Decoupling supply voltage apart from other digital-to-analog Design easy for breadboard converter module. Innovations feature like High quality double sided PCB 2 on-board IC address jumpers, pull-up All SMT components resistors, and power LED. The module Small and compact in size 0.70 x can be quickly connected directly on to 0.47 inches the breadboard. The board is small and Dual row 0.6 width, 0.1 pitch compact in size 0.70 x 0.47 inches. header pins Flexible operating power supply The I2C-DAC is designed base on voltage range of +2.7V to +5.5V DAC5571 IC. It is a low-power, single- Suitable for 3.3V or 5.0V channel, 8-bit buffered voltage output microcontroller DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. Applications The output voltage range of the DAC is 0V to VCC. The I2C-DAC incorporates a Process Control power-on-reset circuit that ensures that the DAC output powers up at zero volts Data Acquisition Systems and remains there until a valid write to the Closed-Loop Servo Control device takes place. Thermostat controls Audio and Video 2 A jumper pins vary the fixed I C address Peripherals and allow up to two devices to share the And much more 2 same I C bus. 2 * I C is a trademark of Philips Semiconductors Corporation.
