These devices perform the same electronic adjustment function as a potentiometer or variable resistor.
Each VR has its own VR latch that daatasheet its programmed resistance value. Stability while driving capacitive loads is another benefit of this design over CMOS rail-to-rail amplifiers.
These VR latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface. Each switch conducts equally well in both directions when ON and each has an input signal range dqtasheet extends to the supplies. This allows designs to achieve higher efficiencies and to transfer more power to the load than dataxheet possible without the use of discrete components.
For applications in which the analog signal is unipolar, the ADGA can be operated from a single rail power supply. If you have questions or suggestions,please leave us a message,we will reply you as soon as we can! The FET-input stage results in a low bias current of 50 pA.
Full-scale settling to 0. It provides a high precision, fully integrated, low cost single-chip solution for generating current loop signals in a compact pin SOIC or PDIP package. Applications Audio and video switching Battery-powered systems Test equipment Communication systems. For users of 3. Applications Mechanical potentiometer replacement Instrumentation: This multiplexer also features high switching speeds and low RON.
It can be used in three-wire or asynchronous mode and a serial-out pin is provided to allow daisy chaining of multiple DACs on the current loop side of the isolation barrier.
When they are on, each switch conducts equally well in both directions and has an input signal range that extends to the power datashfet. Low charge inject is inherent in the design. The small signal bandwidth is kHz at a gain of Analog Devices also offers over 30 other high speed amplifiers from the low noise AD 1.
This yields performance that can be used to implement high accuracy systems, even in single-supply designs. This is useful for driving coax cable or large FET transistors. You can contact us any way that is convenient for you. Home Products News dtasheet. Inherent in the design is low charge injection for minimum transients when datxsheet the digital inputs. A serial data output pin at the opposite end of the serial register AD only allows simple daisy chaining in multiple VR applications without requiring additional external decoding logic.
The Datasueet switches one of 16 inputs to a common output, depending dahasheet the state of four binary addresses and an enable input.

The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. The on-resistance profile is very flat over the full analog input range, ensuring good linearity and low distortion when switching audio signals. The variable resistor offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper.
Low gain error and low nonlinearity make the AD ideal for precision instrumentation applications requiring programmable gain. The only external components that are required in addition to normal transient protection circuitry are three low cost capacitors which are used in the DAC output filter. Eleven data bits make up the data-word clocked into the serial input register. The first three bits are decoded to determine which VR latch is loaded with the last eight bits of the data-word when the CS strobe ad707aw returned to logic high.
Ad770aq switching speed also makes the device suitable for video signal switching. The devices can operate comfortably anywhere in the By using a bipolar front end, lower noise and higher accuracy than those of CMOS designs have been achieved.
Common-mode rejection is a minimum of 78 dB.
CMOS construction ensures ultralow power dissipation, making the device ideally suited for portable, battery-powered instruments.
All switches exhibit break-before-make ar707aq action for use in multiplexer applications. A guaranteed maximum input offset voltage of 0.
In addition, the AD provides excellent dc precision.
Applications Battery-operated instrumentation Servo amplifiers Actuator drives Sensor conditioners Power supply control. To provide flexibility to the system designer, the AD can be operated in either latched or transparent mode. These switches dagasheet feature high switching speeds and low RON. The device is fully specified with a single 12 V supply.
