A Versatile 8-Channel Multiplexer вЂ“ Design Note 112
Kevin R. Hoskins
Introduction
Available in either 16-pin DIP or narrow body SOIC
packages, the CMOS LTC В®1390 is a high performance
8-to-1 analog multiplexer. It is addressed through a
3-wire digital interface featuring bidirectional serial data.
The LTC1390 features a typical on-resistance of 45О©,
typical switch leakage of 50pA and guaranteed breakbefore-make switch operation. Charge injection is В±10pC
(max). All digital inputs remain logic compatible whether
operating on single or dual supplies. The inputs are
robust, easily withstanding 100mA fault currents. The LTC1390 operates over a wide power supply voltage
range of 3V to В±15V.
Low Power, Daisy-Chain Serial Interface,
8-Channel A/D System
Figure 1 shows the LTC1390 connected to the LTC1286
12-bit micropower A/D converter. The Clock (CLK)
and Chip Select (CS) signals are connected in parallel
to the LTC1390 and LTC1286. Both the LTC1390 and
the LTC1286 are designed for serial data transfer. The

Micropower 12-Bit ADCs Shrink Board Space вЂ“ Design Note 116
Kevin R. Hoskins Many portable and battery-powered systems require
internal analog-to-digital conversion. Some, such as
pen-based computers, have ADCs at their very cores
digitizing the pen screen. Other systems use ADCs more
peripherally to monitor voltages or other parameters
inside the equipment. Regardless of the use, it has been
difп¬Ѓcult to obtain small ADCs at power levels and prices
that are low enough. The LTC1286/LTC1298 meet these
low power dissipation and package size needs.
Micropower and 12-Bits in an SO-8 Package
The LTC1286/LTC1298 are the latest members of the
growing family of SO-8 packaged parts (TableВ 1).
As the п¬Ѓrst of their kind in SO-8 packages, these are
improvements to the 8-bit micropower LTC1096/
LTC1098 ADCs. The LTC1286/LTC1298 use a successive approximation register (SAR) architecture. Both
converters contain sample-and-holds and serial data
