Features and Benefits

Features LTC4306, a 4-channel, 2-wire I²C bus and SMBus compatible multiplexer having bus buffers that provide capacitive isolation between the upstream bus and downstream buses
6-pin PMOD connectors for upstream and downstream connection for compatibility with PMOD form factors such as EVAL-ADICUP3029 (Arduino based Wireless Development Platform based on an ultra-low power ARM Cortex-M3 processor) or with EVAL-SDP-CK1Z (SDP-K1 Cortex ARM core processors Controller Board and color sensor)

Product Details

The EVAL-LTC4306-PMDZ features LTC4306, a 4-channel, 2-wire I²C bus and SMBus compatible multiplexer having bus buffers that provide capacitive isolation between the upstream bus and downstream buses. This evaluation board provides 6-pin PMOD connectors for upstream and downstream connection for compatibility with PMOD form factors such as EVAL-ADICUP3029, an Arduino based Wireless Development Platform for Internet of Things applications based on an ultra-low power ARM Cortex-M3 processor.

Pmod^™ is the Digilent defined standard of Peripheral Modules, small I/O interface boards that offer an ideal way to extend the capabilities of programmable logic and microcontroller boards. They allow sensitive signal conditioning circuits and high-power drive circuits to be placed where they are most effective — near sensors and actuators.

EVAL-LTC4306-PMDZ comes with PMOD connectors on both upstream and downstream side for compatibility with PMOD form factors, 10K pull up resistors on upstream and all downstream buses and 0.1uF bypass capacitor on the upstream side. The user has the option to add 6 pin 2.54mm pitch pin header for connection to the GPIOs (General Purpose Input/Output pins) on EVAL-LTC4306-PMDZ for extra functionality. The user also has the option to add test points on different places on the board for fault monitoring and place additional bypass capacitors (0805 size footprint) on the upstream and the downstream side for defense against any unwanted noise in their system for adequate bypassing on power supply lines.
