DC2754A

DC2754A is a LTC4331 I2C device extender over rugged differential link demonstration board. Demonstration circuit 2754A extends an I2C based QuikEval™ interface to up to 450feet and features the LTC®4331. In order to realize the QuikEval interface, this demo circuit includes two complete I2C extenders and a remote side power supply formed from an LT®3461 boost converter and two LT1761 LDOs. The LTC4331 is a SMBus compatible I2C device extender designed for operation in high noise industrial environments. The I2C/SMBus is extended over a single twisted pair by a ±60V fault protected differential transceiver. The LTC4331’s extended 15V common mode voltage range allows it to bridge across different ground potentials.

• Input supply range from 2.6V to 5.5V at TA = 25°C
• Input supply current (VCC + VL) is 70mA at VCC = VL = VL2 = 5V, I(VL2) = 15mA, TA = 25°C
