AD648AQ ANALOG DEVICE

The AD623 is an integrated. or dual-supply instrumentation amplifier that delivers rail-to-rail output swing using supply voltages from 3 V to 12 V. The AD623 offers superior user flexibility by allowing single gain set resistor programming and by conforming to the 8-lead industry standard pin out configuration_ With no external resistor, the AD623 is configured for unity gain (G I), and with an external resistor, the AD623 can be programmed for gains of up to The superior accuracy of the AD623 is the result of increasing ac common -mode rejection ratio (CMRR) coincident with increasing gain; line noise harmonics are rejected due to constant CAIRR up to 200 Hz.

The CA3140 are integrated circuit operational amplifiers that combine the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. The CA3140 BiMOS operational amplifiers feature gate protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance, very low input current, and high speed performance. The CA3140 operate at supply voltage from 4V to 36V (either single or dual supply). These operational amplifiers are internally phase compensated to achieve stable operation in unity gain follower operation, and additionally, have access terminal for a supplementary external capacitor if additional frequency roll-off is desired. Terminals are also provided for use in applications requiring input offset voltage nulling.

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

The 741 series are general-purpose operational ?amplifier which features improved performance over industry standards like LM709. They are direct, Exceeded plug-in replacements for the 709C, LM201, MC1439, and 748 in most applications. The amplifiers offer many features which make theirs application nearly foolproof: overload protection on the input and output, no latch-up when the common mode range is exceeded, as well as freedom from oscillations. The LM741C is identical to the LM741 and LM741A except that the LM741C has their performance ensured over a 0?C to 70?C temperature range, instead of ?55?C to 125?C.
