The devices can operate comfortably anywhere in the If the AD is going to be used at extreme temperatures and supply voltages, an external output transistor can be used to minimize power dissipation on the chip via the “BOOST” pin. It is complete, including amplifier, resistor network and TTL-compatible latched inputs, and requires no external components.
This allows designs to achieve higher efficiencies and to transfer more power to the ad707q than previously possible without the use of discrete components.

Applications Audio and video switching Battery-powered systems Test equipment Communication systems. In addition, the AD provides excellent dc precision.
The device is fully specified with a single datasbeet V supply. Low charge inject is inherent in the design. 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. Common-mode rejection qd707aq a minimum of 78 dB.
You can contact us any way that is convenient for you. 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.
For applications such as transformers that require driving inductive loads, increases in efficiency are also possible. This is useful for driving coax cable or large FET transistors. Stability while driving capacitive loads is another benefit of this design over CMOS rail-to-rail amplifiers. For users of 3. The on-resistance profile is very flat over the full analog input range, ensuring good linearity and low distortion when switching audio signals. The only external components that are required in addition to normal transient protection circuitry are three a707aq cost capacitors which are used in the DAC output filter.
In the off condition, signal levels up to the supplies are blocked. These switches also feature high switching speeds and low RON. For applications in which the analog signal is unipolar, the ADGA can be operated from a single rail power supply. Low gain error and low nonlinearity make the AD ideal for precision instrumentation applications requiring programmable gain. The FET-input stage results in a low bias current of 50 pA. 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.
The ADGA switches are turned on with a logic low on the appropriate control input. By using a bipolar front end, lower noise and higher accuracy than those of CMOS designs have been achieved. These devices perform the same electronic adjustment function as a potentiometer or variable resistor.
When they are on, each switch conducts equally well catasheet both directions and has an input signal range that extends ad7077aq the power supplies.

Product Highlights Extended signal range. CMOS construction ensures ultralow power dissipation, making the device ideally suited for portable, battery-powered instruments. 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.
High switching speed also makes the device suitable catasheet video signal switching.

To provide flexibility to the system designer, the AD can be operated in either latched or transparent mode. The small signal bandwidth is kHz at a gain of Each switch conducts equally well in both directions when ON and each has an input signal range that extends to the supplies. This multiplexer also features high switching speeds and low RON. A guaranteed maximum input offset voltage of 0.
The ADGA switches one of 16 inputs to a common output, depending on the state of four binary addresses and an enable input. Eleven data bits make up the data-word clocked into the serial input register. All switches exhibit break-before-make switching action for use in multiplexer applications. 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 VR has its own VR latch that holds its programmed resistance value. 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 is returned to logic high. The variable resistor offers ac707aq completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper.
