Precision, 4-Channel, Low-Level, Differential Multiplexer
The Intersil HI-539 is a monolithic, 4-Channel, differential multiplexer. Two digital inputs are provided for channel selection, plus an Enable input to disconnect all channels. Performance is guaranteed for each channel over the voltage range ±10V, but is optimized for low level differential signals. Leakage current, for example, which varies slightly with input voltage, has its distribution centered at zero input volts. In most monolithic multiplexers, the net differential offset due to thermal effects becomes significant for low level signals. This problem is minimized in the HI-539 by symmetrical placement of critical circuitry with respect to the few heat producing devices.
