Class Information
Number: 341/154
Name: Coded data generation or conversion > Analog to or from digital conversion > Digital to analog conversion > Using ladder network
Description: Subject matter where the conversion utilizes an impedance network (typically an R\2R ladder network) having a number of nodes equal to the number of bits in the digital signal, each node being selectively fed with equal currents in response to the digital signals and thereby outputting an electrical signal representative of the digital input signal.
