ZANational = Semiconductor LM604 4 Channel Mux-Amp General Description Features The LM604 Mux-Amp is an op-amp with four selectable dif- Multiplexes four differential input channels to a single ferential inputs, combining the functions of a multiplexer ‘op-amp with an op-amp. The LM604 can select, buffer, and amplify ™@ Easy to interface to microprocessor, or operates “stand ‘one of four different input signals, providing a complete sys- alone” tem for multiplexing analog signals. It also has the unique —_™ Bi-State output: Operates in two states, Active and Dis- Bi-State output which allows two or more Mux-Amps to be abled. When disabled, it becomes a high impedance. connected together at their outputs to increase the number —_w Wide operating voltage range of multiplexed channels. Channel selection and the Bi-State single supply 4V to 32V ‘output are controlled by internal logic that interfaces directly split supply +2V to +16V to a microprocessor. Besides these unique features, the @ wide input common mode range V- tov —4V LM604 has excellent AC and DC op-amp specications and Fast channel to channel switching ime Sus rernally compe! i i ‘m Output will drive a 6002 load Applications include signal multiplexing and linear circuits that are controlled by digital signals (i.e., programmable gain blocks, filters, and other op-amp circuits).
