    11-MHz JFET Op Amp
    1 Features 3 Description The OPA140, OPA2140, and OPA4140 operational
    amplifier (op amp) family is a series of low-power
    JFET input amplifiers that features good drift and low
    input bias current. The rail-to-rail output swing and
    input range that includes V– allow designers to take
    advantage of the low-noise characteristics of JFET
    amplifiers while also interfacing to modern, singlesupply, precision analog-to-digital converters (ADCs)
    and digital-to-analog converters (DACs). 1 Very Low Offset Drift: 1 ОјV/В°C Maximum
    Very Low Offset: 120 ОјV
    Low Input Bias Current: 10 pA Maximum
    Very Low 1/f Noise: 250 nVPP, 0.1 Hz to 10 Hz
    Low Noise: 5.1 nV/в€љHz
    Slew Rate: 20 V/Ојs
    Low Supply Current: 2 mA Maximum ...

    Tuning in Amplifiers
    Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket?

    Single-Supply Operation of Operational Amplifiers
    Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.

    Op Amp Performance Analysis
    This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
