LMP2022MA Datasheet PDF - TI

●The LMP2022MA is a zero drift low noise EMI hardened Operational Amplifier offering ultra-low input offset-voltage, near zero input offset voltage drift, very low input voltage noise and very high open loop gain. This op-amp is part of the LMP precision family and is ideal for instrumentation and sensor interfaces. The LMP202x has only 0.004µV/°C of input offset voltage drift and 0.4µV of input offset voltage. 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 of input voltage noise and no 1/f noise component, the op-amp 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.
