In addition, the AD provides excellent dc precision. Low charge inject is inherent in the design.
Stability while driving capacitive loads is another benefit of this design over CMOS rail-to-rail amplifiers. Analog Devices also offers over 30 other high speed amplifiers from the low noise AD 1.
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. By using datsheet bipolar front add707aq, lower noise and higher accuracy than those of CMOS designs have been achieved.
This allows designs to achieve higher efficiencies and to transfer more power to the load than previously possible without the use of discrete components. High switching speed also makes the device catasheet for video signal switching.
To provide flexibility to the system designer, the AD can be operated in either latched or transparent mode.

Applications Audio and video switching Battery-powered systems Test equipment Communication systems. 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. For applications in which the analog signal is unipolar, the ADGA can be operated from a single rail power supply.
All switches exhibit break-before-make switching action for use in multiplexer applications. Full-scale settling to 0. 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 a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper. For applications such as transformers that require driving inductive loads, increases in efficiency are also possible.
You can contact us any way that is convenient for you. A guaranteed maximum input offset voltage of 0. The FET-input stage results in a low bias current of 50 pA. 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.
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. 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 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.

CMOS construction ensures ultralow power dissipation, making the device ideally suited for portable, battery-powered instruments. The ADGA switches are turned on with a logic low on the appropriate control input. When they are on, each switch conducts equally well in both directions and has an input signal range that extends to the power supplies.
Common-mode rejection is a minimum of 78 dB. This yields performance that can be used to implement high accuracy systems, even in single-supply designs.

The device is fully specified with a single 12 V supply. If you have questions or suggestions,please leave us a message,we will reply you as soon as we can! Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
This is useful for driving coax cable or large FET transistors. The on-resistance profile is very flat over the full analog input range, ensuring good linearity and low distortion when switching audio signals.
