Analog Switch Cuts Peak Detector Reset Time - 05/25/95 EDN-Design Ideas
The schematic in Fig 1 is a basic configuration for a unity-gain peak detector
using the PKD-01FP monolithic peak detector from Analog Devices. The reset time,
tRES, is the time necessary to discharge the hold capacitor CH. tRES and the
acquisition time tACQ are functions of the IC's output-current capability. With CH10
nF, this output-current limitation sets both tRES and tACQ to about 220 �sec....

Analog switch expands I2C interface - 22-Nov-01 Issue of EDN Perhaps
the most effective way to gain board space and increase component density is to
minimize wiring on the board. A widely used architecture that allows such
miniaturization is the I2C bus. Comprising only a bidirectional data line, SDA, and
a clock line, SCL, this bus requires no chip selects or other additional
connections.... [Design Idea by Luca Vassalli, Maxim Integrated Products, Sunnyvale,

Analog switch frees stuck I²C bus - 26-Jun-03 Issue of EDN The
dual-channel PCA9540 I2C multiplexer often breaks up an I2C or SM bus or allows you
to use devices with the same addresses on the same bus. When the PCA9540 initially
powers up, it comes up in a state in which both channels are deselected. The I2 C-
or SM-bus master can then address the control register in the PCA9540 to select
either Channel 0 or Channel 1, connecting the master to the ap.... [Design Idea by

Analog switch lowers relay power consumption - 20-Dec-01 Issue of EDN
Designers often use relays as electrically controlled switches. Unlike transistors,
their switch contacts are electrically isolated from the control input. However, the
power dissipation in a relay coil may render the device unattractive in
battery-powered applications. You can lower this dissipation by adding an analog
switch that allows the relay to operate at a lower voltage (Figure 1].... [Design
