LM604A - 4-Channel Mux-Amp

Datasheet Summary

Description

The LM604 Mux-Amp is an op-amp with four selectable dif­ ferential inputs, combining the functions of a multiplexer with an op-amp.

The LM604 can select, buffer, and amplify one of four different input signals, providing a complete sys­ tem for multiplexing analog signals.

Features

  • the LM604 has excellent AC and DC op-amp specifications and is internally compensated.

LM604A/LM604 National S em ico nd u cto r Corporation LM604A/LM604 4 Channel Mux-Amp General Description The LM604 Mux-Amp is an op-amp with four selectable dif­ ferential inputs, combining the functions of a multiplexer with an op-amp. The LM604 can select, buffer, and amplify one of four different input signals, providing a complete sys­ tem for multiplexing analog signals. It also has the unique Bi-State output which allows two or more Mux-Amps to be connected together at their outputs to increase the number of multiplexed channels. Channel selection and the Bi-State output are controlled by internal logic that interfaces directly to a microprocessor. Besides these unique features, the LM604 has excellent AC and DC op-amp specifications and is internally compensated.
