MB88111
s DESCRIPTION
The MB88111 is an analog-to-digital converter that converts its analog input to a 10-bit digital value and outputs it
as serial data.
The MB88111 employs a successive approximation method for A/D conversion. It has 24 input channels to be A/
D converted selectively by setting in an internal register.
Since the MB88111 can input and output 16-bit serial data in synchronization with the clock, it can be easily
connected to the serial I/O port in a 16-bit microcontroller.
