Analog Devices LTC2977 | Demoboard DC1508B-A

Description

The DC1508B programming board contains the circuitry needed to program and verify the EEPROM of the LTC2974, LTC2975, LTC2977, LTC2978, and LTC2978A. This is its sole purpose. The DC1508B is shipped with a clamshellstyle programming socket installed. The EEPROM contains the factory default configuration. The LTpowerPlay™ *.proj file that corresponds to the factory default can be found in the GUI.

To properly program and verify the contents of the EEPROM, download and install the LTpowerPlay software (GUI).

You also need a Linear Technology DC1613 USB to I2C/ SMBus/PMBus Controller.
