The ADG411, ADG412, and ADG413 are monolithic CMOS devices comprising four independently selectable switches. They are designed on an enhanced LC2MOS process which provides low power dissipation yet gives high switching speed and low on resistance.The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion when switching audio signals. Fast switching speed coupled with high signal bandwidth also make the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.The ADG411, ADG412, and ADG413 contain four independent SPST switches. The ADG411 and ADG412 differ only in that the digital control logic is inverted. The ADG411 switches are turned on with a logic low on the appropriate control input, while a logic high is required for the ADG412. The ADG413 has two switches with digital control logic similar to that of the ADG411 while the logic is inverted on the other two switches.Each switch conducts equally well in both directions when on, and each has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.PRODUCT HIGHLIGHTS Extended signal range The ADG411, ADG412, and ADG413 are fabricated on an enhanced LC2MOS, giving an increased signal range which extends fully to the supply rails. Ultralow power dissipation. Low RON Break-before-make switching This prevents channel shorting when the switches are configured as a multiplexer. Single-supply operation For applications where the analog signal is unipolar, the ADG411, ADG412, and ADG413 can be operated from a single-rail power supply. The parts are fully specified with a single 12 V power supply and remain functional with single supplies as low as 5 V.APPLICATIONS Audio and video switching Automatic test equipment Precision data acquisition Battery-powered systems Sample-and-hold systems Communication systems

The ADM1485 is a differential line transceiver suitable for high speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with both EIA Standards RS-485 and RS-422. The part contains a differential line driver and a differential line receiver. Both the driver and the receiver may be enabled independently. When disabled, the outputs are tristated.The ADM1485 operates from a single +5 V power supply. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. This feature forces the driver output into a high impedance state if during fault conditions a significant temperature increase is detected in the internal driver circuitry.Up to 32 transceivers may be connected simultaneously on a bus, but only one driver should be enabled at any time. It is important therefore that the remaining disabled drivers do not load the bus. To ensure this, the ADM1485 driver features high output impedance when disabled and also when powered down.This minimizes the loading effect when the transceiver is not being utilized. The high impedance driver output is maintained over the entire common-mode voltage range from -7 V to +12 V.The receiver contains a fail safe feature which results in a logic high output state if the inputs are unconnected (floating).The ADM1485 is fabricated in BiCMOS, an advanced mixed technology process combining low power CMOS with fast switching bipolar technology. All inputs and outputs contain protection against ESD; all driver outputs feature high source and sink current capability. An epitaxial layer is used to guard against latch-up.The ADM1485 features extremely fast switching speeds. Minimal driver propagation delays permit transmission at data rates up to 30 Mbits/s while low skew minimizes EMI interference.The part is fully specified over the commercial and industrial temperature range and is available in an 8-pin DIL/SOIC package.
