• Manufacturer Part Number: ADG506A
• Description: CMOS 8-/16-Channel Analog Multiplexers
• Manufacturer: Analog Devices

SINGLE SUPPLY AUTOMOTIVE APPLICATION
The excellent performance of the multiplexers under single
supply conditions makes the ADG506A/ADG507A suitable in
applications such as automotive and disc drives where only
positive power supply voltages are normally available. The fol-
lowing application circuit shows the ADG507A connected as an
8-channel differential multiplexer in an automotive, data acqui-
sition application circuit.

The AD7580 is a 10-bit successive approximation ADC, which
has an on-chip sample-hold amplifier and provides a conversion
result in 20 s. The ADC has differential analog inputs and is
configured in the application circuit for a span of 2.5 V over a
common-mode range 0 V to + 5 V. Wider common-mode ranges
can be accommodated. See the AD7579/AD7580 data sheet for
more details. The complete system operates from +12 V (+10%)
and +5 V supplies. The analog input signals to the ADG507A
contain information such as temperature, pressure, speed etc.
