The LMP2022MA/NOPB (购买请点击)are single and dual precision operationalamplifiers offering ultra low input offset voltage, nearzero input offset voltage drift, very low input voltage noise andvery high open loop gain. They are part of the LMP® precisionfamily and are ideal for instrumentation and sensor interfaces.The LMP2022MA/NOPB (购买请点击)have only 0.004 μV/°C of input offsetvoltage drift, and 0.4 μV of input offset voltage. These attributesprovide great precision in high accuracy applications.
The proprietary continuous correction circuitry guaranteesimpressive CMRR and PSRR, removes the 1/f noise component,and eliminates the need for calibration in many circuits.With only 260 nVPP (0.1 Hz to 10 Hz) of input voltage noiseand no 1/f noise component, the LMP2022MA/NOPB (购买请点击)are suitablefor low frequency applications such as industrial precisionweigh scales. The low input bias current of 23 pA makesthese excellent choices for high source impedance circuitssuch as non-invasive medical instrumentation as well as testand measurement equipment. The extremely high open loopgain of 160 dB drastically reduces gain error in high gain applications.
With ultra precision DC specifications and very lownoise, the LMP2022MA/NOPB (购买请点击) are ideal for position sensors,bridge sensors, pressure sensors, medical equipment andother high accuracy applications with very low error budgets.The is offered in 5-Pin SOT-23 and 8-Pin SOICpackages. TheLMP2022MA/NOPB (购买请点击)is offered in 8-Pin MSOP and 8-PinSOIC packages.
