Integrated TAP Monitor Arrays w/ I2C Interface

Integrated TAP Monitor Arrays
w/ I2C Interface
ITMA Series
Product Description
Oplink’s Integrated Tap Monitor Array (ITMA) w/ I2C interface is a compact, multichannel power-monitoring module. Functions of power reading, alarm and
threshold setting are provided at firmware command level thru I2C interface.
There is no hardware design, firmware programming or PD calibration work for
user anymore, which greatly relieves user from heavy work load of design and
manufacturing and provides great cost saving.
Oplink can provide customized designs to meet specialized feature applications.
Also, Oplink offers modular assemblies that integrate other components to form a
full function module or subsystem.
