AD7528LR ANALOG DEVICE

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 INA125 is a low power, high accuracy instrumentation amplifier with a precision voltage reference. It provides complete bridge excitation and precision differential-input amplification on a single integrated circuit. A single external resistor sets any gain from 4 to 10,000. The INA125 is laser-trimmed for low offset voltage (250?V), low offset drift (2?V/?C), and high common-mode rejection (100dB at G = 100). It operates on single ( 2.7V to 36V) or dual (?1.35V to ?18V) supplies. The voltage reference is externally adjustable with pinselectable voltages of 2.5V, 5V, or 10V, allowing use with a variety of transducers.

The LM339? consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit comparators, simple analog to digital converters; pulse, square wave and time delay generators; wide range VCO; MOS clock timers; multi vibrators and high voltage digital logic gates. When operated from both plus and minus power supplies, they will directly interface with MOS logic ? where the low power drain of the LM339 is a distinct advantage over standard comparators.

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.
