LMP202x Zero-Drift, Low-Noise, EMI-Hardened Amplifiers  
1 Features  
3 Description  
The LMP2021 and LMP2022 are single and dual  
precision operational amplifiers offering ultra low input  
offset voltage, near zero input offset voltage drift, very  
low input voltage noise and very high open loop gain.  
They are part of the LMP™ precision family and are  
ideal for instrumentation and sensor interfaces.  
1
(Typical Values, TA = 25°C, VS = 5 V)  
Input Offset Voltage (Typical) 0.4 µV  
Input Offset Voltage (Max) ±5 µV  
Input Offset Voltage Drift (Typical) –0.004 µV/°C  
Input Offset Voltage Drift (Max) ±0.02 µV/°C  
Input Voltage Noise, AV = 1000 11 nV/Hz  
Open Loop Gain 160 dB  
The LMP202x has only 0.004 µV/°C of input offset  
voltage drift, and 0.4 µV of input offset voltage. These  
attributes provide great precision in high accuracy  
applications.  
CMRR 139 dB  
PSRR 130 dB  
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.  
Supply Voltage Range 2.2 V to 5.5 V  
Supply Current (per Amplifier) 1.1 mA  
Input Bias Current ±25 pA  
With only 260 nVPP (0.1 Hz to 10 Hz) of input voltage  
noise and no 1/f noise component, the LMP202x are  
suitable for low frequency applications such as  
industrial precision weigh scales. The extremely high  
open loop gain of 160 dB 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, medical equipment and other high  
accuracy applications with very low error budgets.
