GENERAL DESCRIPTION
The ADG528A and ADG529A are CMOS monolithic analog
multiplexers with eight channels and four dual channels, respectively. On-chip latches facilitate microprocessor interfacing. The
ADG528A switches one of eight inputs to a common output,
depending on the state of three binary addresses and an enable
input. The ADG529A switches one of four differential inputs to
a common differential output, depending on the state of two
binary addresses and an enable input. Both devices have TTL
and 5 V CMOS logic-compatible digital inputs.
The ADG528A and ADG529A are designed on an enhanced
LC2MOS process, which gives an increased signal capability of
to VDD and enables operation over a wide range of supply

voltages. The devices can comfortably operate anywhere in the
10.8 V to 16.5 V single- or dual-supply range. These multiplexers also feature high switching and low R

FUNCTIONAL BLOCK DIAGRAMS
PRODUCT HIGHLIGHTS
1. Single-/dual-supply specifications with a wide tolerance.
The devices are specified in the 10.8 V to 16.5 V range for
both single- and dual-supplies.
2. Easily Interfaced
The ADG528A and ADG529A can be easily interfaced with
microprocessors. The WR signal latches the state of the
address control lines and the enable line. The RS signal
clears both the address and enable data in the latches resulting in no output (all switches off). RS can be tied to the
microprocessor reset pin.
3. Extended Signal Range
The enhanced LC
and an increased analog signal range of V
4. Break-Before-Make Switching
Switches are guaranteed break-before-make so that input
signals are protected against momentary shorting.
5. Low Leakage
Leakage currents in the range of 20 pA make these multiplexers
suitable for high precision circuits.

MOS processing results in a high breakdown
to VDD.
