Specifications of ISL5416KI

• Package: 256BGA
• Operating Supply Voltage: 1.8 V

A test register is provided for the processor to input data to
the part. The register can be selected as the input for any or
all of the channels. The test input is 16 bits of data plus 3 bits
of exponent. The input enable is also controllable by the uP.
The choices are always active, always inactive, and one
