ADC0804LCN 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 INA106 is a monolithic Gain = 10 differential amplifier consisting of a precision op amp and on-chip metal film resistors. The resistors are laser trimmed for accurate gain and high common-mode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The differential amplifier is the foundation of many commonly used circuits. The INA106 provides this precision circuit function without using an expensive resistor network. The INA106 is available in 8-pin plastic DIP and SO-8 surface-mount packages.

The INA118 is a low-power, general-purpose instrumentation amplifier offering excellent accuracy. The versatile, three op amp design and small size make this device an excellent choice for a wide range of applications. Current-feedback input circuitry provides wide bandwidth, even at high gain (70 kHz at G = 100). A single external resistor sets any gain from 1 to 10000. Internal input protection can withstand up to ?40 V without damage. The INA118 is laser-trimmed for low offset voltage (50 ?V), drift (0.5 ?V/?C), and high common-mode rejection (110 dB at G = 1000). The INA118 operates with power supplies as low as ?1.35 V, and quiescent current is only 350 ?A, making this device an excellent choice for battery-operated systems.

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.
