AD7819YR ANALOG DEVICE

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 INA126 is precision instrumentation amplifiers for accurate, low noise differential-signal acquisition. Their two-op-amp design provides excellent performance with low quiescent current (175 ?A/channel). Combined with a wide operating voltage range of ?1.35 V to ?18 V, makes the INA126 ideal for portable instrumentation and data acquisition systems. Gain can be set from 5 V/V to 10000 V/V with a single external resistor. Laser-trimmed input circuitry provides low offset voltage (250-?V maximum), low offset voltage drift (3-?V/?C maximum), and excellent common-mode rejection.

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.

The LM833 is a standard low?cost monolithic dual general?purpose operational amplifier employing Bipolar technology with innovative high?performance concepts for audio systems applications. With high frequency PNP transistors, the LM833 offers low voltage noise (4.5 nV/ Hz ), 15 MHz gain bandwidth product, 7.0 V/s slew rate, 0.3 mV input offset voltage with 2.0 V/?C temperature coefficient of input offset voltage. The LM833 output stage exhibits no dead?band crossover distortion, large output voltage swing, excellent phase and gain margins, low open loop high frequency output impedance and symmetrical source/sink AC frequency response.
