    Operational Amplifier
    1 Features 3 Description The OPA314 family of single-, dual-, and quadchannel operational amplifiers represents a new
    generation of low-power, general-purpose CMOS
    amplifiers. Rail-to-rail input and output swings, low
    quiescent current (150 μA typically at 5 VS) combined
    with a wide bandwidth of 3 MHz, and very low noise
    (14 nV/√Hz at 1 kHz) make this family very attractive
    for a variety of battery-powered applications that
    require a good balance between cost and
    performance. The low input bias current supports
    applications with MΩ source impedances. 1 Low IQ: 150 µA/ch
    Wide Supply Range: 1.8 V to 5.5 V
    Low Noise: 14 nV/√Hz at 1 kHz
    Gain Bandwidth: 3 MHz
    Low Input Bias Current: 0.2 pA ...

    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
