Frequently Asked Questions
How accurate is the LMP2021MF offset voltage and why does it matter for sensor designs?
The LMP2021MF guarantees a maximum input offset voltage of only 10 µV, which minimizes DC measurement error when amplifying small signals from bridge sensors, RTDs, or thermocouples. Even with a gain of 100 V/V, the output error caused by offset is limited to just 1 mV, enabling highly accurate measurements in precision instrumentation.
In what environments does the EMI hardening of the LMP2021MF provide a practical advantage?
The LMP2021MF is hardened against electromagnetic interference typical in motor drives, switching power supply environments, and wireless-enabled industrial systems. In these environments, external EMI can introduce errors of several millivolts in conventional op-amps, while the LMP2021MF maintains a CMRR of at least 105 dB to reject common-mode noise above 50 Hz.
What bias current does the LMP2021MF draw, and which sensor types does this accommodate?
The LMP2021MF draws a maximum bias current of 0.1 µA and an average of only 0.0003 µA, making it compatible with high-impedance sensors such as pH electrodes, ion-selective electrodes, and high-value resistive bridges. At these bias levels, the voltage error across a 1 MΩ source impedance is below 0.1 mV.
How does the LMP2021MF compare to standard precision op-amps for medical device designs?
Compared to standard precision op-amps, the LMP2021MF adds EMI hardening without sacrificing precision, maintaining 10 µV offset and 141 dB typical CMRR in a 5-pin SOT-23 package. Medical devices such as ECG monitors and patient monitoring front-ends benefit from the combination of low offset voltage and immunity to interference from nearby RF transmitters operating at 900 MHz or 2.4 GHz.
