LMP2021MA Datasheet PDF - TI

The LMP2021MA is a single low noise EMI hardened Operational Amplifier offers ultra low input offset voltage, near zero input offset voltage drift, very low input voltage noise and very high open loop gain. It is part of the LMP precision family. These attributes provide great precision in high accuracy applications. The proprietary continuous auto zero correction circuitry ensures impressive CMRR and PSRR, removes the 1/f noise component and eliminates the need for calibration in many circuits. With only 260nVPP (0.1 to 10Hz) of input voltage noise and no 1/f noise component, the LMP202x is suitable for low frequency applications such as industrial precision weigh scales. The extremely high open loop gain of 160dB drastically reduces gain error in high gain applications. With ultra precision DC specifications and very low noise, the LMP202x are ideal for position sensors, bridge sensors, pressure sensors and other high accuracy applications with very low error budgets.
