AD736AQ ANALOG DEVICE

The CA3102 consists of two independent differential amplifiers with associated constant current transistors on a common monolithic substrate. The six transistors which comprise the amplifiers are general purpose devices which exhibit low 1/f noise and a value of fT in excess of 1GHz. These features make the CA3102 useful from DC to 500MHz. Bias and load resistors have been omitted to provide maximum application flexibility. The monolithic construction of the CA3102 provides close electrical and thermal matching of the amplifiers

The INA122 is a precision instrumentation amplifier for accurate, low noise differential signal acquisition. Its two-op-amp design provides excellent performance with very low quiescent current, and is ideal for portable instrumentation and data acquisition systems. The INA122 can be operated with single power supplies from 2.2V to 36V and quiescent current is a mere 60?A. It can also be operated from dual supplies. By utilizing an input level-shift network, input common mode range extends to 0.1V below negative rail (single supply ground).

The LF351 is a low cost high speed JFET input operational amplifier with an internally trimmed input offset voltage (BI-FET IITM technology). The device requires a low supply current and yet maintains a large gain bandwidth product and a fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The LF351 is pin compatible with the standard LM741 and uses the same offset voltage adjustment circuitry. This feature allows designers to immediately upgrade the overall performance of existing LM741 designs. The LF351 may be used in applications such as high speed integrators, fast D/A converters, sample-and-hold circuits and many other circuits requiring low input offset voltage, low input bias current, high input impedance, high slew rate and wide bandwidth

he LF398 devices are monolithic sample-and-hold circuits that use BI-FET technology to obtain ultrahigh DC accuracy with fast acquisition of signal and low droop rate. Operating as a unity-gain follower, DC gain accuracy is 0.002% typical and acquisition time is as low as 6 ?s to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth. Input offset adjust is accomplished with a single pin and does not degrade input offset drift. The wide bandwidth allows the LF398 to be included inside the feedback loop of 1-MHz operational amplifiers without having stability problems. Input impedance of 1010 ? allows high-source impedances to be used without degrading accuracy. P-channel junction FETs are combined with bipolar devices in the output amplifier to give droop rates as low as 5 mV/min with a 1-?F hold capacitor.
