Analog Switch Acts As Dc/Dc Converter:  01/20/00 EDN-Design Ideas / (added 05/03) Many low-current devices that require 65V supplies can operate reliably in a single 5V power-supply environment if you use an appropriate localized dc/dc converter to generate the -5V bias. Often, the capabilities and advantages of these 5V ICs far outweigh the minor inconvenience and added costs of an additional -5V-converter function. Many companies manufacture dc/dc- converter ICs and modules in a variety of power ratings and footprints. However, these typical dc/dc converters can be overkill for simple, single-chip applications that require only a negative bias voltage with low operating currents. For these applications, typical negative-voltage requirements range from -4 to -6V with a supply current of 1 mA, and requirements for the -5V supply are generally noncritical. A lower cost alternative to conventional dc/dc converter modules for generating negative dc voltages from a positive supply uses a low-cost quad- semiconductor....

Analog Switch Expands I 2 C Interface:  11/22/01 EDN Design Ideas  /  (added 12/04)  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. ...

Analog Switch Frees Stuck I²C Bus:  06/26/03 EDN Design Ideas  /  (added 12/04)  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......

Analog Switch Lowers Relay Power Consumption:  12/20/01 EDN Design Ideas  /  (added 12/04)  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). ...

MOSFETs Reduce Crosstalk Effects On Analog Switches:  05/29/03 EDN Design Ideas  /  (added 12/04)  Some cost-effective analog multiplexer/demultiplexer ICs, such as the CD4053 and CD4066, find frequent use as signal distributors. These digitally controlled analog switches have low on-resistance. However, with all channels in the same package, crosstalk can be annoying and unavoidable. Figure 1 provides a cost-effective and viable method of solving this problem....
