HI-539

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.

Supply voltages are

±15V and power consumption is only

2.5mW.
