LC89080 Operation
The LC89080 and LC89080Q include three current-matrix D/A converters on chip. These D/A converters each have 63
basic current cells (with current weight I) and two weighted current cells (I/2 and I/4). These current cells are turned on
or off according to the input digital code (a binary code). The sum of these currents is output to the output pins (IO and
IOB) and the output current is converted to a voltage by the output resistor (RO) to acquire the analog output. The table
shows the ideal relationship between the digital input and the analog output when VREFIN is 1 V.
