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.
