AD644JH 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 INA114 is a low cost, general purpose instrumentation amplifier offering excellent accuracy. Its versatile 3-op amp design and small size make it ideal for a wide range of applications. A single external resistor sets any gain from 1 to 10,000. Internal input protection can withstand up to ?40V without damage. The INA114 is laser trimmed for very low offset voltage (50?V), drift (0.25?V/?C) and high common-mode rejection (115dB at G = 1000). It operates with power supplies as low as ?2.25V, allowing use in battery operated and single 5V supply systems

The LF412 devices are low cost, high speed, JFET input operational amplifiers with very low input offset voltage and input offset voltage drift. They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The LF412 dual is pin compatible with the LM1558, allowing designers to immediately upgrade the overall performance of existing designs. These amplifiers 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 and drift, low input bias current, high input impedance, high slew rate and wide bandwidth.

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.
